OBJECTIVE
To study the chemical constituents of Knoxia corymbosa Willd.
METHODS
Chromatography was used to isolate and purify the chemical constituents, their structures were identified by spectral analysis.
RESULTS
Four flavonol glycosides were identified as quercetin-7-O-alpha-L-arabinosyl-3-O-beta-D-6"-acetylglucopyranoside (1), kaempferol-7-O-alpha-L-arabinosyl-3-O-beta-D-glucopyranoside (2), quercetin-3-O-beta-D-glucopyranoside (3), quercetin-3-O-beta-D-6"-acetylglucopyranoside (4).
CONCLUSIONS
Compound 1 is a new flavonol glycoside. The other flavonol glycosides were isolated from Knoxia corymbosa Willd for the first time.
