Comparative Pharmacognostical, Preliminary Phytochemical and Acute Toxicological Evaluation of Blumea lacera var lacera and Blumea eriantha DC.

The pharmacognostical, phytochemical and toxicological analysis carried out with a focus on diagnostic character will be immense helps in the proper identification and standardization of two botanical species of the Blumea. Blumea is an important genus of family Asteraceae (composite) a important drug used in Ayurvedic medicine. Based on available literature about the plant the Authentification was not available, even the plant have wide traditional therapeutically use so that the Authentification was essential. The first object to evaluate the pharmacognostical characters indicates the authentification and identification by means of morphological, macroscopical, microscopical, physicochemical evaluation, fluorescence studies and preliminary phytochemical evaluation. It may avoid the duplication or substitution with other inferior drug and also adulteration. This study helps in easy and accurate identification of both species giving main concentration on diagnostic characters which may use in differentiation of both species-Blumea lacera var lacera and Blumea eriantha DC. The study helps in the standardization of the herbal drug. The toxicological evaluation helps in dose determination for pharmacological or biological activity evaluation.
