Selective and efficient analytical methods are required not only for quality assurance but also for authentication of herbal formulations. The main objective of the present study is to develop a simple, rapid and validated UV fingerprint method for estimation of total polyphenols as tannic acid in Astangavaleha and crude drugs. Astangavaleha is official in Ayurvedic formulary of India and it is the most common formulation used for respiratory disorders in Ayurvedic medicinal preparation. It Composition of the medicinal important plants Myrica esculenta, Inula racemosa, Pistacia integerrima, Trachyspermum ammi, Carum carvi, Zingiber officinale, Piper nigrum, Piper longum, madhu and Zingiber officinale (svarasa).
