Abstract
Novel alkylphenols, ardisiphenols A—C (1—3) and a novel bergenin derivative, demethoxybergenin (10) were isolated from the fruits of Ardisia colorata (Myrsinaceae), together with known alkylresorcinols (4—6), embelin (7), myricetin (8), quercetin (9), bergenin (11), norbergenin (12), kaempferol (13), quercetin-3-O-β-D-glucopyranoside (14) and gallic acid (15). Their structures were determined by NMR, MS(/MS) analyses and other spectroscopic methods. Ardisiphenols showed moderate scavenging activities toward 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals and showed cytotoxicity against the murine breast cancer cell line, FM3A.Keywords
