Cinnamic acid and lanostenoic acid derivatives from the leaves of Pyracantha crenulata (D. Don) M. Roem
Journal Title: Journal of Pharmaceutical and Biological Sciences - Year 2017, Vol 5, Issue 3
Abstract
Pyracantha crenulata (D. Don) M. Roem. (Rosaceae) is distributed in the northern Himalayas and China as a perennial shrub. The leaves are used to prepare herbal teas, sun burn creams and facial creams and taken as a nervine tonic. An air-dried leaf powder of P. crenulata was exhaustively extracted with methanol. The concentrated leaf extract was adsorbed on silica gel (60-120 mesh) for the preparation of a slurry. The dried slurry was chromatographed over silica gel column packed in petroleum ether. The column was eluted with petroleum ether, chloroform and methanol successively in order of increasing polarity to isolate β-sitosterol, cis-3,4-dioxyethylene-5-methoxycinnamic acid and lanost-54-en-2β,3β-diol 26-oic acid (cranulanostenoic acid). The structures of all the isolated phytoconstituents have been established on the basis of spectral data analysis and chemical reactions.
