摘要
在对月桂叶化学成分的研究过程中，分离到一种新的三萜o -甲基环桂烯醇(1)和一种新的香豆素(+)-7-甲氧基-6-(2' r -甲氧基-3'-羟基-3'-甲基丁基)香豆素(2)。此外，还首次从该植物中分离到5种已知香豆素，分别为异球醇(3)、邻烯醇(4)、5,8-二甲氧基香豆素- 2h -1-苯并吡喃-2- 1(5)、7-甲氧基-6[2'-氧-3'-甲基丁基]香豆素(6)和(+)-乌洛普特罗(7)。用光谱学方法鉴定了化合物3和4的结构，用Horeau方法确定了化合物3和4的C-2′的立体化学结构。
In the course of our studies on the chemical constituents of the leaves of Skimmia laureola, a new triterpene O-methyl cyclolaudenol (1) and a new coumarin, (+)-7-methoxy-6-(2'R-methoxy-3'-hydroxy-3'-methyl butyl) coumarin (2) were isolated. In addition five known coumarins, isogospherol (3), heraclenol (4), 5,8-dimethoxy coumarin-2H-1-benzopyran-2-one (5), 7-methoxy-6[2'-oxo-3'-methyl butyl] coumarin (6), and (+)-ulopterol (7) were also isolated for the first time from this plant. The structures were identified by spectroscopic studies and the stereochemistry at C-2' in compounds 3 and 4 were established by Horeau's procedure.
