Three new chalcone C-glycosides named schoepfin A, B, C (1-3), together with three known compounds 4,2',4'-trihydroxy-3'-C-beta-D-glucosylchalcone (4), nothofagin (5) and hemiphloin (6) were isolated from ethanolic extract of the bark of Schoepfia chinensis Gardn. et Champ (Olacaceae). Their structures were determined mainly by spectroscopic techniques including 2D-NMR (HMBC, HMQC) and MS experiments.
从中国肖榄(铁青树科)树皮的乙醇提取物中分离得到3个新的查尔酮碳苷,分别命名为肖榄苷A、B、C(1 - 3),以及3个已知化合物4,2',4'-三羟基-3'-C-β-D-葡萄糖基查尔酮(4)、异鼠李素(5)和半缩木素(6)。它们的结构主要通过包括二维核磁共振(HMBC、HMQC)和质谱实验在内的光谱技术确定。
