Four new triterpenes, 21alpha-methylmelianodiol (1), 21beta-methylmelianodiol (2), hispidol A 25-methyl ether (3) and hispidol B 25-methyl ether (4), and a new coumarin, isoschininallylol (5), were isolated from the fruits of Poncirus trifoliata RAFINESQUE, along with seventeen known compounds. The structures of the new compounds (1 - 5) were elucidated by interpretation of their spectroscopic data.
从枳(Poncirus trifoliata RAFINESQUE)果实中分离得到4个新的三萜类化合物,21α-甲基蜜茱萸二醇(1)、21β-甲基蜜茱萸二醇(2)、柔毛脂素A 25-甲醚(3)和柔毛脂素B 25-甲醚(4),以及1个新的香豆素类化合物异欧前胡内酯烯醇(5),同时还分离得到17个已知化合物。通过对新化合物(1 - 5)光谱数据的解析确定了其结构。
