    Description / Table of Contents: Studien über die Bestandteile von Jateorhiza palmata Miers (Colombo-Wurzel), II. - Isolierung und Struktur von sechs neuen Furanoid-Diterpen-Glucosiden: Palmatosid B, C, D, E, F und GSechs neue als Palmatosid B(1), C(2), D(3) E(4), F(5) und G(6) bezeichnete Furanoid-Diterpen-Glucoside wurden aus der getrockneten Wurzel von Jateorhiza palmata Miers (Colombo-Wurzel) isoliert. Auf Grund von chemischen und spektroskopischen Beweisen wurden die Strukturen von 1, 2, 3, 4, 5 und 6 als 4-O-(β-D-Glucopyranosyl)chasmanthin, 4-O-(β-D-Glucopyranosyl)columbin, 4-O-(β-D-Glucopyranosyl)isocolumbin, 4-O-(β-D-Glucopyranosyl)isojateorin, 4-O-(β-D-Glucopyranosyl)jateorin, und [2S-(2α,4aα,6aβ,10aβ,10bα)]-2-(3-Furanyl)-6a-(β-D-glucopyranosyloxymethyl)-1,2,4a,5,6,6a,7,10,10a,10b-decahydro-10b-methyl-4H-naphtho[2,1-c]pyran-4,7-dion ermittelt.
    Notes: Six new furanoid diterpene glucosides, named palmatoside B(1), C(2), D(3), E(4), F(5), and G(6) were isolated from the dried roots of Jateorhiza palmata Miers (Colombo root). The structures were elucidated by chemical and spectroscopic evidence to be 4-O-(β-D-glucopyranosyl)chasmanthin, 4-O-(β-D-glucopyranosyl)columbin, 4-O-(β-D-glucopyranosyl)isocolumbin, 4-O-(β-D-glucopyranosyl)isojateorin, 4-O-(β-D-glucopyranosyl)jateorin, and [2S-(2α,4aα,6aβ,10bα,10bα)]-2-(3-furanyl)-6a-(β-D-glucopyranosyloxymethyl)-1,2,4a,5,6,6a,7,10,10a,10b-decahydro-10b-methyl-4H-naphtho[2,1-c]pyran-4,7-dione, respectively.
