Pharmacognostical and Phytochemical Investigation of Calendula Officinalis

Abstract

In the present investigation the leaves of Calendula officinalis Linn (Asteraceae) were studied for their identification, morpho-anatomical, phytochemical characteristics and standardization parameters. Various pharmacognostic parameters including examination of morpho-anatomical, ash value, crude fibre, extractive value and LOD were studied. Phytochemical evaluation including examination of preliminary physicochemical screening and TLC profile has been done. Preliminary phytochemical investigation of different extracts of leaves of Calendula officinalis shows the presence of alkaloids, carotenoids, flavonoids, saponin steroid, tannin and tritrpenes
