Evalution of pharmacognostical and physical parameters of Ayurvedic formulations containing Trachyspermum ammi Linn.

One of the impediments in the acceptance of the herbal products worldwide is the lack of standard quality control profiles.Hence various methods are developed by WHO for the standardization of polyherbal formulations. The present study deals with the standardization of Trachyspermum ammi and its marketed polyherbal formulations “Ajmodadi churna” of four different companies. An attempt has been made to develop standardization method based on the Pharmacognostic and physicochemical parameters of Trachyspermum ammi and its marketed polyherbal formulations “ Ajmodadi churna” of four different companies. The Pharmacognostic and physicochemical profile of Trachyspermum ammi is taken as a reference standard in comparing with four marketed formulations of Ajmodadi churna. Histological parameters like endodermis, epidermis,fibers, cortex, sclereids ,oil globules etc are seen . Extractive value, ash value ,moisture content is found to be 7.4 ,1.2, 4.3 %w/w respectively. The following study will improve the quality of drugs and also motivates the practioners to get more involved in the standardizations of formulations.
