Microscopic studies and preliminary pharmacognostical evaluation of Euphorbia neriifolia L. leaves

Euphorbia neriifolia Linn. (Euphorbiaceae) is commonly known as Indian Spurge Tree in English, and Sehundah in Ayurveda. Its leaves are traditionally used for treatment of various diseases like inflammation, fever, asthma, cough, wounds, ulcers, cancers and diabetes. In the present study an attempt has been made to highlight this folk herbal medicine which will assist in the identification of fresh as well as dried crude samples of leaves anatomically and pharmacognostically. The present study also deals with macroscopic, microscopic, fluorescence, phytochemical characteristics and other WHO recommended methods for standardization of leaf powder. Phytochemical screening and chromatographic studies help in determining the antioxidant potential and predominant classes of active ingredients contribute to the activity. These studies will provide referential information for correct identification and help in checking adulteration in market samples used in the preparation of various herbal medicines. These observations will also be helpful in differentiating the leaves of this species from closely related species of same genus and family.
