Alysicarpusmonilifer DC. (Leguminosae) is a small herb which is well known for its medicinal properties and widely used worldwide. A. monilifer is an important plant of Indian Ayurvedic System of Medicine which is routinely used to treat certain ailments like inflammation, stomachache and jaundice. The present study is intended to evaluate the pharmacognostical and preliminary phytochemical characterization of the leaves and stem of Alysicarpusmonilifer. Since fewer reports are available in this taxon, detailed microscopical and phytochemical studies of this plant were undertaken. All the parameters were studied as per the WHO and pharmacopoeial guidelines. Various parameters like fluorescence analysis and physicochemical constant were also studied. The anatomy of the leaf reveals that adaxial epidermis is stomatiferous and contains prismatic type of calcium oxalate crystals; stomata are paracytic; trichomes are both glandular and non-glandular. The stem shows the presence of hollow vascular cylinder which comprises several independent wedge shaped vascular bundle; xylem elements are surrounded by thick walled fibres. This observation would be immense value in the botanical identification and standardization of the drug in the crude form. This study is used to distinguish the plant from its closely related species. The pharmacognostic characters and phytochemical values reported in this work could be used as a diagnostic tool for the standardization of this medicinal plant. Adulterants if any can be easily identified by adopting fluorescence analysis. The microscopic characters could help in laying down micro-morphological standards as per WHO guidelines for authentication of the drug.
