title: Triterpenoid saponins from Clinopodium chinensis.
abstract: Two new triterpenoid saponins, 3 beta,16 beta,23-trihydroxy-13,28-epoxyolean- 11-en-3-yl-[beta-D-glucopyranosyl(1-->4)-beta-D-glucopyranosyl(1-->3)]- [beta-D-glucopyranosyl(1-->2)]-beta-D-fucopyranoside[1](clinopodiside B) and 28-O-beta-D-glucopyranosyl-3 beta,23-dihydroxyoleana-12,21-dien-3-yl-beta-D-glucopyranosy l-(1-->3)-beta-D- fucopyranoside [3] (clinopodiside C), together with three known saikosaponins, buddlejasaponins IV, IVa, and IVb, have been isolated from the plant, Clinopodium chinensis, and characterized using chemical evidence and spectroscopic methods, in particular 2D nmr spectroscopy.
