[The chemical constituents of Breynia rostrata].
OBJECTIVE
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).


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