| structures of three new oleanene glucuronides isolated from lathyrus palustris var. pilosus and hepatoprotective activity. | three new saponins, named palustrosides i, ii and iii, together with azukisaponins ii, v and soyasapogenol b monoglucuronide, were isolated from the aerial parts of lathylus palustris l. var. pilosus ledeb. the structures of palustrosides i, ii and iii were identified as 3-o-beta-d-glucopyranosyl-(1-->2)-beta-d-glucuronopyranosides of soyasapogenol e, abrisapogenol e, and bredemolic acid 28-o-beta-d-glucopyranoside, respectively, by spectroscopic and chemical methods. as part of our studies on h ... | 1998 | 9775436 |
