| 摘 要： | Two new flavonol glycosides (1 and 2) together with two known flavonoides (3 and 4),were isolated from the whole plant of Knoxia corymbosa willd. The structures of I and 2 were elucidated as kaempferol-7-O-α-L-arabinosyl-3-O-β-D-6“-acetylglucopyranoside and kaempferol -7-O-α-L-arabinosyl-3-O-β-D-3″,6″-diacetylglucopyranoside respectivedly. |
