PHARMACOGNOSTIC AND PHYTOCHEMICAL ANALYSIS OF ASYSTASIA VARIABILIS TRIM. - AN EXTRAPHARMACOPOEAL AYURVEDIC MEDICINAL PLANT
Background - Asystasia Variabilis Trim. also known as Maithaala Kaddi by traditional practitioners of Udupi. Belonging to the family Acanthaceae. Is a semi-scandent herb, and effectively used by the Folklore practitioners for the management of Amlapitta (acid peptic disorder), worm infestations and rheumatism. Aim - To explore the pharmacognostical and preliminary phytochemical parameters of plant to standardize the drug. Materials and Methods - whole mature plant of A.variabilis was collected from Udupi district. Macroscopic, microscopic physico-chemical standards, HPTLC and secondary metabolites screening were scientifically recorded. Results - The pharmacognostical leaf study has shown single layered epidermis throughout midrib and lamina. Anatomical features of stem exhibit single layer of epidermis covered with trichomes. Inner to this, densely arranged collenchyma cells are present. In transverse section of root showed epidermal layer is surrounded by root hairs which are abundant. Powder microscopy characteristics showed the presence of starch in parenchyma region, mesophyll cells with stomata and sclerides were present. The standard out print of the drug is represented by physicochemical standards and HPTLC. Preliminary Phytochemical study shows that it contains Alkaloids, Carbohydrates, Steroids, Tannins and Phenol. Conclusion - Pharmacognostical study carried out on A.variabilis showed quality standards of the drug, with respect to its macroscopy, microscopy, physico-chemical standards and HPTLC.
