Secondary metabolites produced during different seasons in some arid medicinal plants

Abstract

The present study was carried out to evaluate the variations in the total amount of secondary metabolites during different seasons in four important valuable medicinal plants, viz. Barleria prionitis, Boerhavia diffusa, Citrullus colocynthis and Grewia tenax of the Indian Thar desert. Results revealed that maximum amount of secondary metabolites (total alkaloids and phenols) were observed during summer, while minimum in rainy season.
