Iridoidal glucosides from Gentiana rhodantha.
Six new iridoidal glucosides, 2'-O-(3''-hydroxybenzoyl)-8-epikingiside (1), 2'-O-(3''-hydroxybenzoyl)-kingiside (2), 6'-O-p-coumaroyl-8-epikingiside (3), loganic acid 11-O-beta-glucopyranosyl ester (4), 6'-O-beta-glucopyranosyl secologanoside (5), and 6'-O-beta-glucopyranosyl secologanol (6), together with seven known iridoidal glucosides, loganic acid (7), 6'-O-beta-d-glucopyranosyl loganic acid (8), 8-epikingiside (9), kingiside (10), secologanoside (11), secoxyloganin (12), and alpigenoside (13), were isolated from the whole plant of Gentiana rhodantha (Gentianaceae). Their structures were elucidated by detailed spectroscopic analysis and chemical methods.
