Aim To differentiate the genuine cassia bark from its substitutes and adulterants. Methods Six components, phenylpropyl acetate, cinnamyl acetate, cinnamaldehyde, cinnamyl alcohol, coumarin, and cinnamic acid were used as characteristic markers, and an optimized TLC method was developed. Results The TLC profile of cassia bark is similar to its closely related variety Cinnamomum cassia Presl var. macrophyllum Chu but significantly different from other six Cinnamomum species. High content of phenylpropyl acet...
Six Chemical Constituents were isolated from the underground parts of Globba racemosa Smith (Zingiberaceas)and identitied as friedelin(1),cycloeucalenol(2) 3-hydroxy-stigmast -5-7-one(3), stigmast-5-en-7-one (5) and sitosterol(6) based on spectral data. 1-5 wereisolated form the Plants of Zingiberaceae family for the first time and triterpenoids were found in Zingiberaceae for the first time too.
