Two new hemiterpene glucosides named pubescenosides A and B were isolated from the root of Ilex pubescens. Their structures were elucidated on the basis of spectroscopic and chemical evidence as 2-(trans-caffeoyloxy)methyl-3-hydroxy-1-butene-4-O-beta-D-glucopyranoside and 2-hydroxymethyl-3-caffeoyloxy-1-butene-4-O-beta-D-glucopyranoside, respectively. Pharmacological investigation on pubescenosides
从冬凌冬青的根中分离出两个新的半萜烯糖苷,分别命名为青春皮苷A和B。在光谱和化学证据的基础上阐明了它们的结构,即2-(反式-咖啡酰氧基)甲基-3-羟基-1-丁烯-4-O-β-D-吡喃葡萄糖苷和2-羟甲基-3-咖啡酰氧基-1-丁烯-4-O-β-D-吡喃葡萄糖苷。对pubescenosides A和B的药理研究表明,它们均具有有效的抗血小板凝集活性。
