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).
CONCLUSIONS
Compounds 1 and 2 are new compounds; 3 and 4 were isolated from Breynia rostrata Merr. for the first time.
