摘要：为了找出适宜的漆蜡萃取条件,进行了热回流萃取漆蜡的单因素和正交试验,并采用GC-MS色谱分析了陕西野漆树和江西引种日本野漆树中漆蜡脂肪酸的化学成分。结果表明:漆蜡萃取的优化工艺条件为石油醚萃取、回流温度80℃、固液比1∶20、萃取时间60min、提取2次;两个产地的漆蜡主要由棕桐酸、油酸和硬脂酸等脂肪酸甘油酯组成,三者之和大于70%,同时都含有十三烷二酸、甘二烷二酸和二十烷二酸;陕西漆蜡中,二元酸含量为8.256%,引种的日本漆蜡二元酸含量为14.097%。
In order to find the optimum conditions for lacquer wax extraction,a thermal reflux method was used in single factor and orthogonal experiments.Then using a gas chromatography-mass spectrometry （ GC-MS） analytical method,the primary fatty acids and their contents of lacquer wax from Shaanxi and Jiangxi provinces were investigated.The results indicated that the optimum extraction conditions for lacquer wax were obtained with petroleum ether as solvent,a temperature of 80℃ ,a solid-liquid ratio of 1∶ 20 and an extraction time of 60 min,for twice extraction.The main components of the lacquer wax from both Shaanxi and Jiangxi provinces were palmitic acid,oleic acid and octadecanoic acid,which together constituted more than 70% of the wax.As well,tridecanedioic acid,docosanoic acid and eicosanedioic acid were found in the lacquer wax.The content of dibasic acids in lacquer wax from Shaanxi accounted for 8.256% of the lacquer wax and for 14.097% in the Jiangxi wax.
