| 1 | A New Diterpene Acid from the Flowers of Heteropappus altaicus显示文摘A new compound, named heteraltaic acid was isolated from the flowers of Heteropappus altaicus (willd) Novopokr.. The compound was elucidated as (5R, 6S, 8aS) –5- [2-(3-furyl ) ethyl-5, 6, 8a-trimethyl-4a, 5, 6, 7, 8, 8a -hexahydro-1-naphthalenecarboxylic acid] by the combination of 1D and 2D NMR techniques (HSQC, HMBC) and X-ray analysis. | QingHuaLIU JunShanYANG YangLU QiTaiZHENG LiMAO | 2005 | Chinese Chemical Letters2005，16，7： | 3 |
| 2 | A New Dihydroflavone Glycoside from Glycyrrhiza uralensis显示文摘A new dihydroflavone glycoside was isolated from the underground parts of Glycyrrhiza uralensis. Its structure was elucidated as 7-hydroxyl-4′-O-]3-D-(6″-O-α-hydroxylpropionyl) glucopyranosyl dihydroflavone by spectral methods. | HongXiaLIU WenHanLIN JunShanYANG | 2004 | Chinese Chemical Letters2004，15，8： | 2 |
| 3 | Hemislin B Glucoside, a New Lignan from Hemistepta lyrata显示文摘From the ethanolic extract of the whole plant of Hemistepta lyrata Bunge., a new lignan, named hemislin B glucoside, has been isolated and identified as a-(trans-3-methoxy-4-O-b-D-glucopyranosylbenzylidene)-b-(3,4-dimethoxybenzyl)-g-butyrolactone. Its structure has been established on the basis of UV, IR, FABMS, 1H-NMR, 13C-NMR, HMQC and HMBC spectral analysis. | YuLinREN JunShanYANG | 2002 | Chinese Chemical Letters2002，13，9： | 1 |
