云南透骨草的化学成分研究

Chemical Constituents of Gaultheria yunnanensis

从云南透骨草全草95%乙醇提取物中分离得到11个化合物,经波谱分析鉴定为山奈酚3-O-α-L-吡喃鼠李糖苷(1),番石榴苷(2),滇白珠甲苷(3),槲皮苷(4)(,-)-5'-甲氧基异落叶松脂醇9-O-β-D-木糖苷(5),五味子苷(6)(,–)-表儿茶素(7),异槲皮苷(8),金鸡纳素Ia(9),熊果酸(10)和2,5-双-(β-苯乙基)苯酚(11)。其中化合物1、2、9和11为首次从该植物中分得,化合物11是首次报导的天然产物。

Eleven compounds were isolated from the 95% ethanol extract of the whole plants of Gaultheria yunnanensis,which were identified to be kaempferol 3-O-α-L-rhamnopyranoside（1）,guaijaverin（2）,gaultheroside A（3）,quercitrin（4）,（-）-5′-methoxyisolariciresinol 9-O-β-D-xylopyranoside（5）,schizandriside（6）,（-）-epicatechin（7）,isoquercitrin（8）,cinchonain Ia（9）,ursolic acid（10）,and 2,5-bis（β-phenylethyl）phenol（11）.Among them,1,2,9 and 11 were firstly obtained from the plant,and 2 was reported as natural compound at the first time.
