Leucanthoside A, a new allose-containing triterpenoid saponin (1), was isolated from the aerial parts of Cephalaria leucantha L. Its structure was determined by electrospray ionization mass spectrometry and NMR spectroscopy. Complete assignments of the 1H and 13C NMR chemical shifts were achieved by two-dimensional NMR experiments: DQF-COSY, NOESY, TOCSY, HSQC, DINE-HSQC, HMBC, 13C-1H 2D-J-resolved spectroscopy, and 1,1-ADEQUATE. 相似文献

Three new kaempferol glycosides, kaempferol 3‐O‐β‐D ‐glucopyranosyl‐(1→6)‐β‐D ‐galactopyranosyl‐7‐O‐α‐L ‐rhamnopyranoside ( 1 ), kaempferol 3‐O‐β‐D ‐galactopyranosyl‐7‐O‐β‐D ‐glucopyranosyl‐(1→3)‐α‐L ‐rhamnopyranoside ( 2 ), and kaempferol 3‐O‐β‐D ‐glucopyranosyl‐(1→6)‐β‐D ‐galactopyranosyl‐7‐O‐β‐D ‐glucopyranosyl‐(1→3)‐α‐L ‐rhamnopyranoside ( 3 ), were isolated from the whole herbs of Cardamine leucantha, along with three known kaempferol glycosides, kaempferol 7‐O‐α‐L ‐rhamnopyranoside, kaempferitrin, and kaempferol 3‐O‐β‐D ‐galactopyranosyl‐7‐O‐α‐L ‐rhamnopyranoside. Their structures were elucidated on the basis of spectroscopic methods. 相似文献
