Two new coumarins (9 and 10) and a new chromone (14), together with eight known coumarins (1-8) and three known chromones (11-13), which were identified by comparison with authentic samples, were isolated from the roots of Coelopleurum gmelinii (D.C.) LEDER (Umbelliferae). The structures of 9, 10 and 14 were established as 6-[(1R, 2S)-1, 3-dihydroxy-2-isovaleryloxy-3-methylbutyl]-7-methoxycoumarin, 6-[(1R, 2S)-2-angeloyloxy-3-β-D-glucosyloxy-1-hydroxy-3-methylbutyl]-7-methoxycoumarin (tert-O-glucosylangelol A) and (S)-7-β-D-glucosyloxymethyl-4-hydroxy-2-(1-hydroxy-1-methylethyl)-2, 3-dihydro-5H-furo [3, 2-g] [1] benzopyran-5-one (prim-O-glucosylangelicain), respectively.
从根中分离出两种新香豆素(9 和 10)和一种新色酮(14),以及通过与真实样品比较而鉴定的八种已知香豆素(1-8)和三种已知色酮(11-13) Coelopleurum gmelinii (D.C.) LEDER(伞形科)。 9、10和14的结构确定为6-[(1R,2S)-1,3-二羟基-2-异戊酰氧基-3-甲基丁基]-7-甲氧基香豆素,6-[(1R,2S)-2-当归酰氧基-3-β-D-葡萄糖基氧基-1-羟基-3-甲基丁基]-7-甲氧基香豆素(叔-O-葡萄糖基当归醇A)和(S)-7-β-D-葡萄糖基氧基甲基-4-羟基-2-(分别为1-羟基-1-甲基乙基)-2, 3-二氢-5H-呋喃[3, 2-g] [1]苯并吡喃-5-酮(prim-O-葡萄糖基当归素)。
