The pharmacognostic standards of fresh, powdered and transverse sections of Hyptis suaveolens (L.) leaf were carried out to determine its macroscopic, microscopical (both qualitative and quantitative), analytical standards and phytochemical profile. The macroscopy revealed a simple leaf, oppositely arranged along the stem with a dark green colour on the outer surface and pale green on the inner surface, ovate in shape and bilateral base, acute apex with a serrate margin. The qualitative microscopy of the powdered leaf shows xylem vessels parenchymal cells with diacytic type of stomata. Also epidermal cells with stoma wall, polygonal parenchymatous and collenchymatous cells making up the cortex with starch grains; non-glandular uniserate, multicellular septate trichome, irregular shaped prisms of calcium oxalate crystals and small bundle of mucilage cells. The quantitative microscopy of the leaf showed the values of palisade ratio, stomatal number (upper and lower epidermal stomatal index (upper and lower surface), vein-islet number and vein termination number to be 5.10, 50stomata/mm2, 80 stomata/mm2, 12.33, 23.14, 35/mm2 and 20/mm2 respectively. For the analytical standards; 9.90 \%, 1.67 \%, 0.38 \% 6.39 \%, 0.61 \% w/w, 1.16 \% w/w, 11.70 \% and 7.25\% were obtained for total ash, water soluble ash, sulphated ash, acid insoluble ash, alcohol soluble extractive value, water soluble extractive value, moisture content and fibre content respectively. The qualitative phytochemical analysis on Hyptis Suaveolens leaves showed presence of carbohydrates, reducing sugar, tannins, flavonoids, steroids, glycosides, terpenoids, alkaloids and saponins. These specific standards obtained are of importance in the establishment of diagnostic indices for the standardization, identification and preparation of monograph on the plant.

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.

Background: Hygrophila auriculata (Schumach.) Heine synonym Hygrophila spinosa T. Anderson is used in the homoeopathic system of medicine belongs to the family Acanthaceae. Plant contains terpenoids, alkaloids, flavonoids and is traditionally known as an aphrodisiac, renal tonic and for its health-promoting properties, this drug is most popularly used by homoeopathic practitioners for the treatment of urticaria, conjunctivitis, gastroenteritis, nausea etc. Complete morphological characterization of whole plant has not been reported so for. This study may provide complete information on the basis of morphological, anatomical and powdered studies. That will assist to differentiate between adulterants and authentic raw drug to maintain the quality of drugs. Objective: The aim of the present study is to examine the morpho-anatomical, powder and fluorescence analysis of whole plant i.e. root, stem, and leaf of the plant used in homoeopathy. Material and methods: The macroscopical, microscopical and powdered analysis of drug was performed. For morphological study simple observational methods applied while for anatomical and bio-statistical parameters microscopy including powder microscopy was performed by using different methods. Results: The drug was in form of dried pieces of leaves, small quadrangular pieces of stem with spines and roots. Microscopy showed few features like aerenchymatous cortex in the middle region of root; semi-quadrangular outline, four vascular bundles at each corner in young stem and developing fascicular vascular bundles between them, in mature stem 6 vascular bundles viz. 4 vascular bundles at corner and 2 vascular bundles present in between opposite to each other; broad cortical aerenchyma in mature stem, leaf amphistomatous, anomocytic stomata, crescent-shaped meristele in leaf. Conclusion: Present study can assist the diagnostic characters of Hygrophila spinosa may be taken as pharmacognostical standards for the identification of plant drug.

Introduction: Grape (Vitis vinifera L.) is one of the largest fruit crop widely grown throughout the world and their seeds are considered a relevant source of polyphenol compounds. Objective: To carry out phytochemical and pharmacognostic evaluation of the seeds of Vitis vinifera L. Var sahibi and hussaini, family vitiaceae as per WHO guidelines. Materials and Methods: In present investigation, the detailed pharmacognostic studies were carried out in terms of organoleptic properties, macroscopical, microscopical characters, physicochemical parameters, preliminary phytochemical screening for major groups of compounds and other WHO recommended parameters for standardization of the seeds of Vitis vinifera L. Var. sahibi and hussaini. Results: Macro and microscopic characters of Vitis vinifera L. seeds Var. sahibi and hussaini were analyzed. Physicochemical parameters such as foreign matter, extractive values, ash content, pH and fluorescent behaviour of seed powder were done by using WHO recommended parameters. A preliminary phytochemical screening was done and revealed the presence of different phytoconstituents like carbohydrates, flavonoids, glycosides, tannins, sterols and fixed oil. Conclusion: This is the first report of its kind on the pharmacognostic studies of Vitis vinifera L. seeds Var. sahibi and hussaini and will serve as valuable source of information towards establishing pharmacognostic standards on identification, purity, quality and classification.

Background:Combretum albidum G. Don commonly known as Buffalo calf. The C. albidum is used for diverse health ailments in traditional and folklore remedies. Objective: The present study was undertaken to lay down pharmacognostic and phytochemical standards for Combretum albidum G. Don. Material and Methods: The pharmacognostic studies were carried out in terms of macroscopic, microscopic, physicochemical, fluorescence and phytochemical analysis. Physicochemical parameters such as total ash, moisture content, extractive values are determined as per WHO guidelines. The microscopical features of root components are observed with Nikon labphoto 2 microscopic unit. Results: The morphologically, root are pale brown colored, cylindrical with slightly bitter in taste and agreeable odour. Distinguishingly roots showed root scares, rootlet and fibrous fracture. Microscopy of root consists of thick epidermis, periderm, and cortex with sclerenchyma cells. Vascular cylinder includes thin phloem and thick, solid and dense xylem cylinder. The prismatic calcium oxalates were observed. Powder microscopy of root revealed that fibres were fairly wide and densely packed with starch grains. The fluorescence and physicochemical standards for root were established. Phytochemically root showed the presence of carbohydrate, glycoside, saponin, flavonoid, phytosterols and phenolic compounds. Conclusion: There is no pharmacognostic and phytochemical reports on C. albidum to authenticate and differentiate them from similar species. Therefore, present work was undertaken and established the pharmacognostic and phytochemical characteristics of C. albidum and diagnostic features to differentiate it.
