Hederagenin, delta-hederin [hederagenin alpha-L-arabinoside], kalopanax-saponin A [hederagenin 3-O-alpha-L-rhamnosyl(1-->2)-alpha-L- arabinoside], kalopanaxsaponin I [hederagenin 3-O-beta-D-xylosyl(1-->3)-alpha-L- rhamnosyl(1-->2)-alpha-L-arabinoside], and sapindoside C [hederagenin
The seeds of Nigella sativa var. hispidula are widely used in food preparation by the Uighur people in western China. Recently, series of oleanane triterpenoid saponins were extracted from the seeds of Nigella sativa var. hispidula, especially α-hederin as
In the present study, effects of various hederagenin monodesmosides isolated from the stem bark of Kalopanax pictus Nakai, such as hederagenin, 5-hederin, kalopanaxsaponin A, kalopanaxsaponin 1, and sapindoside C, have been evaluated on lipopolysaccharide (LPS)-induced nitric oxide (NO),
The roots of Cephalaria ambrosioides yielded a new triterpene, 6alpha-hydroxyhederagenic acid ( 1), in addition to the known triterpene hederagenic acid ( 2) and four corresponding saponins, leontoside A (or akeboside Stb) ( 3), kalopanax saponin A (or alpha-hederin) ( 4), saponin PG (or sapindoside
Eight previously undescribed oleanane-type triterpenoid saponins, clematangoticosides A-H, together with eight known saponins, were isolated from the whole plants of Clematis tangutica (Maxim.) Korsh. Their structures were elucidated by extensive spectroscopic analysis, in combination with chemical
