Introduction: Annona muricata Linn. (Family: Annonaceae) is a well-known traditional and natural medicine over the world; in Malaysia it serves as a treatment for many kinds of diseases. Studies have been reported that A. muricata can be used to treat diseases due to its antibacterial, antiviral, antifungal, antitumor, anthelmintic, analgesic, hypotensive, antiinflammatory, and has immune enhancing properties. Despite having several medicinal functions and properties, however there is no standardization parameters have been reported in the literature for the leaves of A. muricata. Methods: Therefore, through this research study, the macroscopical and microscopical characteristics, physicochemical parameters such as ash values, extractive values, fluorescence analysis and preliminary phytochemical analysis of the leaves were investigated. Results: Based on the observation of the transverse section of the leaves, the presence of upper cuticle, upper epidermis, palisade cells, vascular bundle, spongy mesophyll, phloem fibers, lignified vessels, xylem vessels, collenchyma, lower epidermis, lower cuticle and parenchyma served as important key differentiating features for the studied plant. The powder microscopy revealed the presence of pieces of trichrome, collapsed uniseriate multicellular covering trichrome, spongy mesophyll, phloem fibres, xylem vessels, paracytic stomata and fragment of epidermis showing cell and palisade cell. Calcium oxalate crystals were also observed even though the captured image was slightly unclear. The phytochemical screening of the leaves was carried out using four different extracts which showed the presence of steroids, saponins, flavonoids, tannins carbohydrates and proteins, respectively. Conclusion: Based on this research finding, the pharmacognostic standardization of the plant can be established thus, providing ease in identifying and determining the purity and quality of the investigated plant.

Introduction: The roots of Capparis erythrocarpos are used traditionally across Africa for the management of pain, arthritis and other forms of inflammatory conditions. Owing to its proven efficacy, it has gained commercial value, particularly as a key ingredient in several herbal products and alcoholic beverages. The increased scarcity owing to demand outstripping supply lend the roots of C. erythrocarpos to adulteration. This paper presents a detailed pharmacognostic evaluation of the leaf, stem and root of C. erythrocarpos which will be used in its identification and consequent standardization. Methods: The leaf, stem and root were evaluated for their macroscopic and microscopic features as were the physicochemical parameters and phytochemical screening done. Results: Leaves are alternately arranged, have collateral vascular bundle, crystal sheaths and a pericyclic fibre. Actinocytic stomata and secretory cells were contained in powdered leaves. The stem showed lenticels and thorns, stellate and branched trichomes which leave off cicatrices in older stems. The powdered stem and roots contained stone cells, secretory cells and scalariform vessels. However, the roots lacked thorns, trichomes and had smaller secretory cells. Aqueous and ethanolic extracts of the leaves, stem and roots were slightly acidic to neutral. Ash values of leaves, stem and roots are (16.58 {\textpm} 0.09) \% w/w, (5.01 {\textpm} 0.09) \% w/w and (6.53 {\textpm} 0.19) \% w/w respectively. Preliminary phytochemical screening of the leaves, stem and roots showed the presence of glycosides, flavonoids and tannins. Conclusion: The determined parameters for the leaf, stem and root of C. erythrocarpos constitute quality parameters for their unequivocal identification.

The aim of the present study was to evaluate physicochemical and phytochemical analysis of different parts (ripe seed, unripe seed, ripe peel, unripe peel and stem) of Indian mango (var. \‘Kesar\’) collected from Saurashtra region of Gujarat. The physiochemical properties such as loss on drying, total ash value, acid insoluble ash value, water soluble ash value and extractive values were carried out. The phytochemical properties such as alkaloids, flavonoids, tannins, phlobatanins, triterpenes, steroids, saponins and cardiac glycosides were also carried out. In phytochemical analysis, tannins showed maximum amounts in all five parts. The present study provides the details physicochemical and phytochemical properties of different parts of kesar mango which are useful in laying down standardization and pharmacopeia parameters.

Background:Cyathula prostrata (Blume) L. from the family Amaranthaceae has been used traditionally for rheumatism, dysentery, wounds and urethral discharges in the tropical regions of the world. Aim: The present study was undertaken to perform quality control standardization and to evaluate antioxidant activity of the leaf, stem, root and the whole plant of Cyathula prostrata. Methods: Macroscopic and microscopic evaluations were carried out on the plant using standard procedures. Powdered sample of the leaf was evaluated with various organic solvents for fluorescence. The chloroform, ethyl-acetate and methanolic extracts of the leaf, stem, root and whole plant were subjected to various pharmacognostic analyses and evaluated for in vitro antioxidant activity using DPPH assay.Further, thin layer chromatoghraphy was used to evaluate the chloroform extract. Results: Important epidermal features in the plant include: coastal cells, unbranched, uniseriate, multicellular and non-glandular trichomes. Leaves are amphistomatic showing mostly anomocytic and actinocytic stomata. Starch grains are restricted to the adaxial surface. Vascular bundles are mainly collateral and well-developed bundle sheath. The transverse section of stem is circular, hypodermis (1-3 layers). Cross section of the root is described in detail for the plant. Cortex has angular cells. Fluorescence studies showed different colours. Physico-chemical results are comparable with standards. The TLC profile showed presence of at least seven compounds in the leaf, root and the whole plant extracts, while nine components were obtained from the stem extract. The ethyl acetate extract of the root and ethanol extract of the stem gave the highest phenolic contents (30.09\±3.768 mg GAE/g) and DPPH free radical scavenging activity (87.0 \± 0.208), respectively. Conclusion: The distinctive features established in this study are steps in identification, standardization and quality control of this medicinal plant.

Background: An ethnomedicinally important plant, Cordia dichotoma Linn is practiced in various indigenous systems of medicine and popular among the various ethnic groups in India for the cure of variety of ailments as an astringent, anthelmentic, diuretic, demulcent, anti-diabetic and expectorant. Because of the increasing demand, maintaining quality standards is the need of the day. Aims and Objectives: The present study was designed to set standard pharmacognostical, physicochemical, phytochemical, fluorescence and HPTLC chromatographic profile of the leaves of Cordia dichotoma Linn (CD). Materials and Methods: CD, which was previously authenticated, was subjected to pharmacognostical, physicochemical, fluorescence and high performance thin-layer chromatography (HPTLC) analysis as per standard protocol. Results and Conclusion: The final observations were recorded. The loss on drying at 105\ºC was found to be 8.5\% w/w, total ash value 13\% w/w, acid-insoluble ash 5.07\% w/w, water-soluble ash 5.49\% w/w, water-soluble extractive 9.2\% w/w, alcohol-soluble extractive 5.81\% w/w and pH (1\% aqueous extract) 6.88. Phytochemical screening showed the presence of steroid, carbohydrate, alkaloid, saponin, cardiac glycosides, flavonoid and phenolic compounds in methanolic extract. The CD fluorescence was seen in UV light and it was of different colour in different solvents. HPTLC analysis revealed 5 peaks at wavelength 366 nm with max Rf values in the range of 0.3 to 0.93. The purity and quality of the leaves of Cordia dichotoma or pharmaceutical preparations prepared from it can be tested by pharmacognostical, physicochemical, fluorescence and HPTLC observations of the present study..
