ent-Abietane diterpenoids, hebeiabinins A–F (1–5), together with seven known diterpenoids were isolated from leaves of Isodon rubescens var. rubescens. The structures of 1–5 were established on the basis of spectroscopic analyses, including application of 2D NMR spectroscopic techniques. The diterpenoids isolated were evaluated for the cytotoxicity against A549, HT-29, and K562 tumor cells. Compound...
Four triterpenoid saponins were isolated from Berneuxia thibetica. On the basis of chemical and spectroscopic evidence, three new saponins, berneuxia saponins A, B and C, were elucidated as 21-tigloylbarringtogenol C-3β-O-α-l-rhamnopyranosyl(1 -> 2)-β-d-galactopyranosyl(1 -> 3)[β-d-glucopyranosyl (1 -> 2)-β-d-glucuronopyranoside], 28-tigloylbarringtogenol C-3β-O-α-l-rhamnopyranosyl(1 ->...
