Abstract

AIM:To study the chemical constituents of Breynia rostrata Merr. METHODS:Chromatography was used to isolate and purify the chemical constituents, their structures were identified by spectral analysis. RESULTS:Four glycosides were identified as 6-O-methylpropanoyl-alpha-D-glucopyranoside (1), 4"-phenolic-6-O-methylpropanoyl-beta-D-glucopyranoside (2), 1-O-galloyl-beta-D-glucopyranoside (3), arbutin (4). CONCLUSION:Compounds 1 and 2 are new compounds; 3 and 4 were isolated from Breynia rostrata Merr. for the first time.
