摘要
从法国产夏枯草（ＰｒｕｎｅｌｌａｖｕｌｇａｒｉｓＬ．）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－ｉｃｈｉｇｏｓｉｄｅＦ＿２，ｓｅｒｉｃｏｓｉｄｅ，槲皮素（ｑｕｅｒｃｅｔｉｎ），槲皮素－３－Ｏ－葡荡糖甙（ｑｕｅｒｃｅｔｉｎ３－Ｏ－ｇｌｕｃｏｓｉｄｅ），山奈酚－３－Ｏ－葡荡糖甙（ｋａｅｍｐｆｅｒｏｌ－３－Ｏ－ｇｌｕｃｏｓｉｄｅ），及ａｒｊｕｎｇｌｕｃｏｓｉｄｅⅠ和ｎｉｇａ－ｉｃｈｉｇｏｓｉｄｅＦ＿１的混合物。它们的结构是通过波谱的方法证明的。
Two new ursane glucosides,pruvuloside A and B,together with five known compounds,niga-ichigoside F_2,sericoside,quercetin, quercetin-3-glucoside,kaempferol-3-O- glucoside,and a mixture of niga-ichigoside F_1 and adunglucoside Ⅰ were isolated from the MeOH extract of Prunella vulgaris collected in France. Their structures were detennined by means of spectral evidence.
