constituents were the camphane derivatives, representing >30% (camphor, 21.3%; borneol, 6.2%; bornyl acetate, 3.5%) of the whole oil, and santolina alcohol (19.3%). The enantiomeric distribution of 8 chiral constituents was determined by GC-MS using two enantioselective stationary phases (DIME-beta-CD and Lipodex-E). Racemic santolina alcohol, required for optimization of the enantioselective GC conditions,
采用气相色谱法(GC)和气相色谱-质谱法(GC-MS)研究了可西嘉岛li草的香精油。初步确定了占油的94.0%的82种化合物。主要成分是樟脑衍生物,占全油的> 30%(樟脑,占21.3%;冰片,占6.2%;乙酸冰片酯,占3.5%),以及圣多那娜醇(占19.3%)。使用两个对映选择性固定相(DIME-β-CD和Lipodex-E)通过GC-MS确定8种手性成分的对映体分布。优化对映选择性GC条件所需的消旋Santolina醇是由2,5-二甲基己基2,4-二烯通过原始的两步合成制备的。使用纸盘法测试了整个香精油对多种细菌的抗菌活性。
