[Studies on chemical constituents of Arachniodes rhomboidea].
OBJECTIVE
To study chemical constituents of Arachniodes rhomboidea.


METHODS
Silica gel column chromatography and Sephadex LH -20 gel column chromatography were employed for the isolation and purification. The structures were identified on the basis of spectral data and chemical methods.


RESULTS
Six compounds were isolated and identified as follows: kaempferol (1), kaempferol-3-O-alpha-L-rhamnoside (2), kaempferol-3-O-beta-D-glucoside (3), kaempferol-3, 7-O-alpha-L-dirhamnoside (4), quercetin-3-O-beta-D-glucoside (5), kaempferol-3-O-beta-D-rutinoside (6).


CONCLUSIONS
Compouds 1-6 were isolated from this plant for the first time.
