- Tinospinosides D, E, and Tinospin E, further clerodane diterpenoids from Tinospora sagittata
-
Chemical investigation on the roots of Tinospora sagittata resulted in the isolation of three novel cis-clerodane diterpenoids, tinospinosides D, E, and tinospin E, together with two known compounds, columbin and columbin glucoside, and their structures w

- Studies on the Constituents of Jateorhiza palmata Miers (Colombo Root), II. - Separation and Structure of Six New Furanoid Diterpene Glucosides: Palmatoside B, C, D, E, F, and G
-
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 -2-(3-furanyl)-6a-(β-D-glucopyranosyloxymethyl)1,2,4a,5,6,6a,7,10,10a,10b-decahydro-10b-methyl-4H-naphthopyran-4,7-dione, respectively
