概要
Two new flavonoids, kaempferol 7-O-(2-E-p-coumaroyl-alpha-l-rhamnoside) (1) and kaempferol 7-O-(2,3-di-E-p-coumaroyl-alpha-l-rhamnoside) (2), together with 10 known compounds were isolated from the flowers and fruit of Tetrapanax papyriferus. Compounds 1 and 2 showed cytotoxicity by brine shrimp lethality bioassay with LC(50) values of 0.57 and 0.40 mM, respectively.
