microscopic character of ginger rhizome

The rhizome is considered the most useful part of the plant. Rhizome. A quiescent center was present in all the three cases as indicated by the light stainability of its cells. A cork cambium is not evident. There are different types of rhizomes: (a) Straggling rhizome: The elongated less branched rhizome which grows horizontally is called straggling rhizome. Macroscopic & Microscopic Molecular-associated Treatments of Monosodium Glutamate-induced Uterine Fibroid via Aqueous Extract of Ginger Rhizomes: A Study on Adult Female Wistar Rats . During stage seven, the underground branch reaches the soil level. Scitamineoe), a reed-like plant producing leafy stems a metre high, springing from branching rhizomes. After the development of 6 to 12 scale leaves and 3 to 5 sheath leaves, the foliage leaves are produced. In the ginger rhizome, four to eight companion cells per sieve tube element are arranged in vertical lines with transverse end walls. Many scattered, collateral, closed vascular bundles are present, of which the greater number is seen in the inner cortical zone. 5, 1, 2, 5, 10 g/kg body weight and ginger oil (0.625, 1.250 and 2. The above characteristics show their state of rest and are called the quiescent center. The part of ginger that's used most often is the root. Ginger is a gnarled rhizome that adds a distinctive sharp bite to baked goods and savory foods. A. J. Olanrewaju 1,2*, J. O. Owolabi 1, S. Y. Olatunji 1, E. I. Oribamise 1, O. I. Omotuyi 3 and A. The cells composing this tissue vacuolate earlier than the outer cells of the cortex. Uses: Ginger is used as a carminative and aromatic stimulant. The nature of the shoot apex: Shah and Raju (1975b) investigated the nature of the shoot apex in ginger. fungi causing ginger rhizome rot in Brazil. The rhizome pieces of Z. officinale were washed with tap water to remove soil and were made to 1–2 cm long pieces. In the present study, the effect of ginger (rhizome of Zingiber officinale Roscoe) volatile oil on a rat model of colitis was evaluated. The procambial cells and the ground meristem cells divide and parenchyma as well as vascular tissues add thickness to the newly enhanced axillary bud. The aerial shoots have many narrow leaves borne on very short petioles and with sheaths that are long and narrow, and the overlapping sheaths produce the aerial shoot. Anatomical Features of Ginger in Comparison with Related Taxa. The cells of this zone located on the flanks exhibit T-divisions, which help the tissue to widen out. Near the dome, cells take less stain because of their quiescent nature. The cells outer and inner to the cambial layer become filled with starch grains. Two kinds of apices are found in ginger: (1) the apices are low dome and surrounded by either scale leaves or leaf bases, and (2) they are dome shaped and raised on an elongated axis. Under white light the chromatogram of the test solution shows three violet zones at Rf ~ 0.24, Rf ~ 0.27, and Rf ~ 0.29 corresponding to reference substance 6-gingerol, 8-gingerol and 10-gingerol. H. Darkening of cell contents and increase in vacuolation. Zingiber officinale Roscoe   Zingiberaceae   Infected rhizome of ginger showing water soaked lesion were collected from farmers’ field of Ri-Bhoi district in Meghalaya. Such cells act as the oil cell mother cell. Such roots carry out the functions of support as well as absorption (Figure 2.4). 4. As a rule there is no secondary growth in monocots. If more than one branch from the parent rhizome is responsible for the ultimate growth and development of the adult rhizome, the branches of the mature rhizome lie in the same plane (Shah and Raju, 1975a). Some cells of pr1 and pr2 (see Figure 2.7) showed dense stainability for C-RNA (cytoplasmic RNA). Later the slime body disintegrates. The same pattern of growth is continued for successive branches to form a sympodial growth pattern. Stationary Phase Stationary phase, i.e. (1) An inner system of ‘scattered’ vascular bundles which serial cinematography reveals to have an axial pattern conforming to the basic ‘palm’ configuration (a system of upwardly branching leaf traces with interconnections). The stem has nodes with scale leaves and internodes. It has cytoplasm and nucleus in early stages, which degenerate during its development into the sieve tube. Derivatization reagent: Anisaldehyde reagent Preparation: 170 mL of ice-cooled methanol are mixed with 20 mL of acetic acid, 10 mL of sulfuric acid, and 1 mL of anisaldehyde. Macroscopical characters: (i) General appearance: Sympodial branching, horizontal rhizome. The development of a new rhizome is by the enhancement of a dormant axillary bud, which acts just like the main shoot apex. The rhizome is buff coloured, laterally compressed, bearing pper side, each sometimes having a depressed scar at the apex; the whole rhizomes are about 5-10 cm long, 1.5-3 cm or 4 cm wide and 1-1.5 cm thick, sometimes split longitudinally. Isolation of Fungi from Ginger (Zin-giber officinale)using Blotter Method Fungal pathogens associated with ginger were isolated using standard … Endodermis differentiates from the innermost periblem cells. They provided anatomical notes on 18 genera and some 70 species (Tomlinson, 1956). It is covered with a brownish skin that may either be thick or thin, depending upon whether the plant was harvested when it was mature or young. The leaves are arranged in a distichous manner. The leaf sheath is about 15 to 18 cm and lamina about 12 to 15 cm long. The main axis developing from the apical bud, which is the first developing branch, has 7 to 15 nodes, which later. Source: Encyclopedia of Life http://eol.org/data_objects/24891510[9], Ginger Flower (Zingiber officinale) Fig 2: Plant of Amomum compactum Soland ex. Fig.1: Rhizome of Zingiber zerumbet (L) Smith. The early studies on the anatomy of ginger were carried out mainly by the pharmacog-nosists, and they concentrated on the officinal part, the rhizome, either dry or fresh (Futterer, 1896). In the underground stem the nodes have scale leaves that ensheath and protect the axillary buds. Primary finger (first-order branch). 1. Fitzp. Ginger is the underground rhizome of the ginger plant with a firm, striated texture. A distinct continuous layer of epidermis is generally present, consisting of a single row of rectangular cells; in some cases, it may be ruptured. The phyllotaxy of the scale leaves on the rhizome and foliage leaves on the aerial stem is distichous, with an angle of divergence of about 180°. See more. status of research in the pharmacological activities of ginger. Ginger also contains 0.25 to 3.0% volatile oil, which contains zingiberene, Citral, borneol. Pungent, spicy ginger root is one of traditional root herb of culinary and medicinal importance. Identification: Compare result with reference images. Pillai et al. The macroscopic and microscopic characters, physical constant values, extractive values, ash values and the behaviour of powder drug on treatment with different chemical regents, microchemical and histochemical analyses were conducted to characterize some pharmacognostical parameters of Curcuma amada linn. 5 out of 5 stars (800) 800 reviews $ 19.95. Zingiber zerumbet Smith or wild ginger is remarkable for its inherent resistance to Pythium spp., which cause soft rot disease in Zingiber officinale Rosc. The lysigenous type of duct formation is more frequent in the meristematic region, but occurs in mature parts too. Secondary finger (second-order branch). The rhizome (underground part of the stem) is the part commonly used as a spice. Pinyin name(s): jiang; sheng jiang (fresh rhizome); gan jiang (dried rhizome); pao jiang (prepared rhizome); jiang pi (peel), The odor of ginger [rhizome] is aromatic and penetrating, the taste spicy, pungent, hot, and biting. As this tiller grows, its base enlarges into a rhizome. At stage five, the apex is a low dome having 214 to 248 ^m height and 53 to 75 ^m width. These cells can be distinguished from the surrounding cells by their meristem-atic activity, stainability, and size of the nucleus. (1961), Aiyer and Kolammal (1966), and Shah and Raju (1975b). During further development, the vacuolation increases and the cytoplasm shrinks and appears like a thread along the wall. 1 lb Fresh Organic Ginger Root/Rhizome - Grown on our Herb Farm in Mississippi - USDA Certified Organic PJHerbal. Inner to the cork is the cortex that is about 4 mm in thickness, composed of thin-walled large hexagonal to polygonal parenchymal cells. Procambial differentiation: The peripheral or flank meristem divides periclinally and produces parenchymal cells. The flank meristem is situated on either side of the central mother zone. This character combined with the response of these cells to stains such as pyronin-methyl green indicates that these cells are in a state of comparative repose and hence are not synthesizing nucleic acids (Pillai et al., 1961). Source: Elan M. Sudberg, Alkemist Laboratories[13]. The development of leaves and scale leaves that encircle the shoot apex in ginger rhizomes is in a clockwise direction. Ginger, the rhizome of Zingiber officinale, is one of the spices widely used worldwide for various foods and as an herbal medicine [3] . In ginger all the underground branches show a negative geotropic response. Division of mother cell. These ducts anastomose and appear branched in longitudinal section. A distinct mid rib is present only in the lamina. Shah and Raju (1975b) recognized seven developmental stages of the apical bud. This cell continues to divide, forming four to eight cells. one rhizome are in regular order, which finally give rise to a complete rhizome (Figure 6.2). The peripheral zone (pr1) is concerned with the initiation of the next leaf primor-, Figure 2.8 Ontogeny of shoot apex: (A) dormant rhizome with stage 1 root apices; (B) rhizome with stage 2 shoot apex; (C) rhizome with stages 5, 6, and 7 root apices; (D) aerial apex showing topographical zonation; (E) rhizome apex showing topographical zonation. A few cells toward the flank showed increased concentrations of DNA as evidenced by dense staining. 1. 2. Some of the cells are distinguishable from the rest by deeper stainability, smaller size, less or no vacuolation, and darkly stained nuclei. AHPA recognizes other valuable resources exist regarding the identity of Zingiber officinale. Ayurvedic name(s): ardraka (fresh rhizome); shunthi (dried rhizome)   Oct 2, 2016 - Science Image of Ginger rhizome showing oil globules from PS MicroGraphs. Rhizome enlargement in ginger is by the activity of three meristematic zones. 1 Bulletin of Health, Science and Technology BHST ISSN 0858-7531 Volume 14, Number 1, 2016 : 01-09 MICROSCOPIC INVESTIGATION OF CURCUMA PETIOLATA ROXB. An atmospheric pressure ion-source chamber enables us to analyze fresh samples with minimal loss of intrinsic water or volatile compounds. In between these cells, certain cells in the cortical zone are distinguishable from the rest by their large size, dense cytoplasm and prominent nucleus (see Figure 2.7A). D. A main axis with four primary branches and their subsequent branches developing in the same plane. It has a pH of 5.6 to 5.9, similar to that of figs, fennel, leeks, Ginger composes novel phytochemical compounds and holds a special place, even today, in many traditional Indian and Chinese medicines for its disease preventing and health promoting properties. The large cell is the sieve cell. These bundles have only one to three vessels and a small phloem.

Likewise, many buds become active during favorable conditions, each of which produces secondary or tertiary rhizomes. Ginger root nutrition facts. (Source: Shah and Raju, 1975.). During subsequent development of the rhizome apex the cells derived from the inner axial zone elongate and contribute to the pith. The shoot apex dome at stage four is 140 to 160 ^m high and 90 to 116 ^m wide. Beneath the epidermis is a brownish, resinous, almost homy cortical portion. Outer corpus cells are vertically elongated. The outermost three to five rows of cortical cells are not rich in oil contents. a group of oil cell initials (see Figure 2.7B—E). From shop PJHerbal. Rhizome of ginger (Zingiber officinale) was collected from Navajyothisree Karunakara Guru Research Centre for Ayurveda and Siddha, Uzhavoor, Kottayam and was used as the source material for the isolation of endophytic bac-teria. These roots are thicker, milky white in color, with few root hairs, and no lateral roots. A violet zone at Rf ~0.53 corresponding to 6-shogaol is present. The characteristic flavor of ginger is due to zingerone, shogaols, gingerols, and volatile (essential) oils that comprise up to 3% of ginger on fresh weight basis . Periblem consists of the initials of the cortex extending from the hypodemis to the endodermis. In primary tissues the oil duct development is schizogenous, whereas further development proceeds both schizogenously and lysigenously. Source: United States Dispensatory (1918) [3]. 2016, 14 (1): 01-09 Phadungcharoen et al. In certain cases these cells extend up to the base of the axillary buds. An empty cell or cells with distorted cytoplasm appear along the duct lumen. It also contains 50% starch, 2 to 3 % proteins and a small amount of sugar. Sample Preparation Method Sample: Mix 1 g of powdered sample with 10 mL of methanol and sonicate for 10 minutes, then centrifuge or filter the solutions and use the supernatants / filtrates as test solutions. There are four stages involved in its development: initiation, differentiation, secretion, and quiescence. The internodal length is more in secondary, tertiary, and quaternary branches, and in the aerial stem it ranges from 3 to 7 cm. Between these fusiform initials, some cells show transverse divisions to form ray initials. Results: In the second week results revealed EMF exposure The oil cell frequency was found to be 17.8/mm2 in ginger, whereas the corresponding frequency in the other species was 9.5, 5.3, and 2.8/mm2 in Z. zerumbet, Z. macrostachyum, and Z. roseum, respectively.

Source: Köhler, Medizinal-Pflanzen in naturgetreuen Abbildungen und kurzerläuterndemTexte (1887)[6], Ginger rhizomes (Zingiber officinale) insects, animal faeces, mold, fungi, etc.) Currently, the trait of vascular bundles collateral in a ring in endodermis is regarded as a basis for the identification of ginger ( Chinese Pharmacopoeia Commission, 2015 ); based on our research, these vascular bundles are not present in the endodermis, but rather in the pericycle. The Jamaica or white ginger is white or yellowish-white on the outside. (Source: Shah and Raju, 1975a.). From either side of the mother rhizome, branches arise and they grow out and become the primary tillers (Figure 2.5). The phloem element consists of the sieve tube, companion cells, parenchyma and fiber. These are the fibrous roots, and the number of such roots keeps on increasing with the growth of. b. divides more frequently c. have larger nuclei and nucleoli d. vacuolation is absent or not prominent. is a creeping perennial on a thick tuberous rhizome, which spreads under ground. ii. What Is the Keto Diet and Should You Try It? Unlike in many monocots, in ginger rhizome there is a special meristematic layer along with the endodermoidal layer, and this layer consists of cambium-like cells. The leaf is initiated from the outer tunica layer and from the flank meristem. Roots always develop just below the nodal region. Such ‘rhizomes are called sobole rhizomes. These steps are a gradual process that occurs acropetally (Figure 2.7). Rhizomes store starches and proteins and enable plants to survive underground during unfavorable seasons. In a longisection, the shoot apex is dome shaped with a single tunica layer, below which the central mother cell zone is present. Test for adulteration: Under UV 366 nm no green or blue fluorescent zones are seen at Rf ~ 0.22 and 0.34 (Lesser galangal rhizome). Answer/Explanation: – ‘A’ shows the nodes of the rhizome of ginger. Each vascular bundle consists of phloem, composed of small thin-walled polygonal cells with well-marked sieve tubes and xylem composed of one to nine vessels with annular, spiral or reticulate thickenings. one rhizome are in regular order, which finally give rise to a complete rhizome (Figure 6.2). In the fresh state, it has a characteristic staghorn-like ap­pear­ance; dried ginger is usually sold in form of an off–white to very light brown powder. 3. The following discussion is adapted from Pillai et al. The sieve tube elements are arranged end to end to form columns of sieve tubes. Appearance . Ginger is called by different names in different parts of the world such as Zingiberis rhizome, Shen jiany, Cochin, Asia ginger, Africa ginger and Jamaican ginger (Peter 2000). Similar tracheids are present in Z. macrostachyum, whereas in Z. zerumbet and Z. roseum, only scalariform thickening occurs (Ravindran et al., 1998). It is a herbaceous perennial which grows annual pseudostems (false stems made of the rolled bases of leaves) about one meter tall bearing narrow leaf blades. Figure 2.3 Floral diagram of ginger flower. as well as identifying the plant by characteristic tissue features. In ginger, the roots emerge 2. Figure 6.2 The rhizome of ginger. The transection of a fresh, unpeeled rhizome is almost circular or oval, about 2 cm in diameter, with the outline almost regular. The plant has narrow; lanceolate to linear-lanceolate, This zone includes cells belonging to all the structural histogens of the root body (i.e., not structurally delimitable). Some studies were carried out by Pillai et al. is widely used as spice and medicinal plant in folk and traditional medicines. Ginger translation in English-Kinyarwanda dictionary. The buds on the secondary fingers in turn can develop into tertiary tillers and tertiary fingers. Ginger (Zingiber officinale) is a herbaceous perennial plant of the family Zingiberaceae which used as a spice, food, flavouring agent, and medicine. Further development leads to the disintegration of nuclear content of the central cell, which stretches toward the intercellular space. Huge collection, amazing choice, 100+ million high quality, affordable RF and RM images. Later a longitudinal slit is formed through which the shoot tip projects. They measure 30 X 30 to 114 X 48 ^m. At the same time, the nucleus disintegrates and the cell assumes the features of the enucleated sieve tube element. This is in direct connection with the vascular ring situated beneath the endo-dermoidal layer. In longisection the quiescent center resembles an inverted cup. It has been used for thousands of years as a medicine for a multitude of ailments. Within this is the cork, varying in thickness from 480 to 640 ^m and differentiated into an outer region 300 to 400 ^m in thickness, composed of irregularly arranged, tangentially elongated, slightly brown-colored cells, and an inner zone of 6 to 12 regular rows of thin-walled rectangular to slightly tangential elongated cells arranged in radial rows. C. Two main axes developing from the seed rhizome, and their subsequent branches developing in the same plane. It is delimited by the shell zone on the rhizome apices, which appears as an arc of narrow cells in median longitudinal section. As a lifetime disorder, ulcerative colitis (UC) is an inflammatory bowel disease (IBD) that affects quality of life and also demands long-term interventions. The secondary wall thickening in the tracheids of ginger is of two types, scalariform and helical. The rhizome may be long and straight as in most species ofHedychium, it may also be branched as in Zingiber. 61. Secretory ducts are formed both schizogenously and lysigenously (Remashree et al., 1998; Ravindran et al., 1998). DOAJ is an online directory that indexes and provides access to … Habit. They are spherical and densely stainable. is one of the major disease of the ginger (.Zingiber officinalis Rose.) Introduction: Ginger (Zingiber officinale Rosc.) It is found in water grasses (typha). pylori Inhibition and Anti-Oxidative Mechanism. These axillary branches are plagiotropic and then they quickly show orthotropic growth at their distal region and subsequently become aerial shoots (see Figure 2.5). Mother rhizome. Outside the plerome dome all cells of the periblem exhibit T-divisions initially but later in development show anticlinal divisions, and the endodermis is differentiated at that time. 50 ml/kg body weight) was administered by intraperitoneal injection to male mice. The root cap is not differentiated into columella and a peripheral zone, and hence there are no separate initials for these regions. MICROSCOPICAL EVALUATION . The shoot apex is 91 to 112 ^m in width and 134 to 167 ^m in height. Introduction Ginger (Zingiber officinale Rosc.) Microscopic examination is a conventional method for identification crude drugs. Tertiary finger (third-order branch). The internodal length of the rhizome branches ranges 0.1 to 1.5 cm, and varies even in a single branch. Later the central cell disintegrates and the contents spill into the cavity thus formed (see Figure 2.7I). (1998). The schizogenous type of secretory duct originates in the intercalary meristem of the developing regions. The apex of stage six is prominently dome shaped having a width of 169 to 200 ^m and height of 87 to 96 ^m. Other Notes Images presented in this entry are examples and are not intended to be used as basis for setting specifications for quality control purposes. 4. This page has been accessed 46,977 times. The ducts are initiated by the separation of a group of densely stained meristematic cells through dissolution of the middle lamella. I. camphene and phellandrene. Chronic toxicity studies have not raised suspicion of other organ changes. Ultimately the vascular bundles are found scattered in parenchymal ground tissue. In the present study, various concentrations of extract prepared from Z. zerumbet were screened for its activity against Pythium myriotylum. Specialists in Science Images.
