Abstract: Two new ursane glucosides, pruvuloside A and B, together with five known compounds, niga-ichigoside F2,sericoside,quercetin,quercetin-3-glucoside, kaempferol-3-0-glucoside, and a mixture of niga-ichigoside F1, and arjunglucoside I were isolated from the MeOH extract of Prunella vulgaris collected in France. Their structures were determined by means of spectral evidence.

摘要： 从法国产夏枯草（Prunella vulgaris L．）的甲醇提取物中分离得到两个新的乌索烷型三萜皂甙：夏枯草甙（pruvuloside)A和B; 同时还分离到5个已知化合物：niga-ichigoside F2，sericoside，槲皮素(quercetin），槲皮素-3－O-葡萄糖甙(quercetin 3－O－glucoside），山奈酚-3－O-葡萄糖甙(kaempferol－3－O－glucoside），及 arjunglucoside I和iga－ichigoside F1 的混合物。它们的结构是通过波谱的方法证明的。
