摘 要:以环己烷为提取剂,采用微波辅助萃取法提取花梨木挥发油。通过正交试验分析,确定了最佳的提取工艺条件为:①花梨木质量(g)与环己烷体积(mL)比20:250,②微波提取10 min,③微波提取功率600 W,④微波提取温度60℃。在此条件下测得花梨木挥发油收率可达1.98%。用气相色谱-质谱联用法,鉴定出21种化学成分,其主要成分为2-氨基-苯酚(27.43%),橙花叔醇(24.83%),(E)-2-长松针烯-4-醇(24.65%),2-(5-甲基-呋喃)丙醛(7.38%)和1,1-二甲基-2-(2-甲基-2-丙烯基)-环丙烷(4.67%)。The volatile oil in dalbergia odorifera was extracted by microwave assisted extraction of sample with cyclohexane as extractant. By using the orthogonal experimental designing, the technological conditions for extraction of volatile oil from dalbergia odorifera were determined as follows: (1) m (Dalbergia odorifera)-V (cyclohexane) ratio: 20 to 250 (g : mL) ; (2) time of microwave extraction: 10 min; (3) power of extraction: 600 W; (4) temperature of extraction: 60 ℃. The yield of volatile oil fouad under the optimum conditions was 1. 98%. Tweenty one compounds were found and identified by GC-MS. The main compounds and their contents were found as follows: 2-amino- phenol (27. 43%), nerolidol (24. 83%), (E)-2-carerr4-ol (24. 65%), 2-(5-methyl-furan)- propionaldehyde (7. 38%) and 1,1-dimethyl-2-(2-methyl-2-propenyl)-cyelopropane (4. 67%).
