Abstract

The present communication attempts to evaluate the macroscopy, microscopy, physico-chemical, preliminary phytochemical and Thin Layer Chromatography (TLC) fingerprint studies of different extracts on the flowers of Justicia adhatoda L. (Adhatoda zeylanica Medicus, A. vasica Nees). Microscopical studies revealed that flowers possess abundant uniseriate, biseriate and multiseriate elongated trichomes, glandular trichomes with bicelled heads, cystoliths in calyx region, light brown tannin content, papillae like out growth, and well developed spongy and palisade parenchyma in corolla region. Preliminary phytochemical screening of the extracts showed the presence of alkaloids, carbohydrates, flavonoides, phenols, proteins, saponins and tannins. These parameters will be useful in the identification and standardization of the flower drug of Vasa and also to identify other species of Adhatoda.

Abstract

Sesame is a condiment which is used in every household for culinary, religious and medicinal purposes. The present study deals with pharmacognostical and physicochemical evaluation of different varieties (black, white and brown) of Sesame (Sesamum indicum Linn.). The study revealed that the different varieties of Sesame seeds, microscopically shows all most similar characters, however, distribution of oil globules varies only in the case of black variety seeds. Oil globules and reddish contents are more in case of white variety when compared to other brown and black. Comparative study has taken up to identify the different varieties of Sesame with respect to its macroscopy, microscopy and other parameters like physico-chemical, preliminary phytochemical, fluorescence and TLC studies.

Keywords
