摘要
利用旋转带分馏、快速柱层析、高压液相色谱、制备气相色谱等方法,从勒(木党)Zanthoxylumavicennae(Lam.)DC.果精油中共分离得到27个化合物,鉴定了其中22个化合物。4-甲基-6-乙酰氧基己醛为在天然界中首次获得。对15个化合物样品做了抑菌试验,其中柠檬醛、正辛醇、芳樟醇和4-甲基-6-乙酰氧基己醛具有强的抑菌活性。本文还讨论了某些精油成分结构与其抑菌活性的相关性。
By means of rotatory belt fractional distillation,LC,HPLC,PGC and derivative methods, 27 compounds were separated from the essential oil which isolated from Zanthoxylum avi- cennae (Lam.) DC.by stream distillation.Twent two of them were identified by the methods of IR,GC/IR,,~1H-NMR,^(13)C-NMR,GC/MS/DS and the preparation of derivatives.Among them, 4-methyl-6-acetoxyhexanal was first found in nature.Fifteen compounds have been tested their antimildew activities.Citral,1-octanol,4-methyl-6-acetoxyhexanal and linalool showed strong activities.The relationships between the structure of compounds of essential oil and their respective antimildew activities are also dealt with in this paper.
