[Study on chemical constituents from Desmodium styracifolium].
OBJECTIVE
To investigate the chemical constituents from Desmodium styracifolium (Osheck) Merr..


METHODS
Column chromatographic techniques were used for isolation and purification of chemical constituents of the plant and the structures were elucidated hy spectroscopic analysis.


RESULTS
Nine compounds were isolated and identified as: 6-C-glycopyranosyl-8-C-arabinosyl apigenin (I),6-C-glycopyranosyl luteolin (2), 6-C-glyeopyranosyl-8-C-xyvloeyl apigenin (3), 6-C-glycopranosyl-8-C-glyeopyrnosyl, apigenin (4), apigenin(5), luteolin (6), stigmasterol-3-O-beta-D-glucopyranoside (7), beta-dauosterol (8) and B-sitosterol (9).


CONCLUSIONS
Com-pounds 4-8 are isolated from this plant for the first time.
