摘　　要：为了有效利用和厚朴的树枝,在1.5、1.7、2.1 MPa等不同压力条件下,对和厚朴树枝进行高压水蒸气蒸馏以提取有效成分厚朴酚与和厚朴酚。对蒸馏液和废液进行气相色谱-质谱(GCMS)分析,并以有机溶剂提取出的厚朴酚与和厚朴酚作为全部提取量,计算厚朴酚与和厚朴酚的转移率。结果表明,1.5 MPa高压水蒸气蒸馏的精油收率为4.53%,厚朴酚与和厚朴酚的转移率分别为33.61%和30.59%。2.1 MPa高压水蒸气蒸馏的精油收率最高(9.05%),但是厚朴酚与和厚朴酚的转移率比1.5 MPa条件下的转移率降低。在高温高压条件下,短时间内从和厚朴树枝中得到了高提取率的厚朴酚与和厚朴酚。和厚朴的蒸馏压力越高,各成分的提取率越高,但随着压力的增加,提取成分有可能发生化学变化。In order to utilize the twigs of Magnolia obvata effectively,they were extracted with high pressure steam distillation method to get magnolol and honokiol under three different pressure conditions,1. 5,1. 7,2. 1 MPa. GC-MS was conducted to analyze the distillate and waste,and the yield of essential oil and the transfer rate of each component under different pressures were compared. The yield of essential oil under the high pressure of 1. 5 MPa was 4. 53%,and the transfer rates of magnolol and honokiol were33. 61% and 30. 59%,respectively. The yield of essential oil under the high pressure of 2. 1 MPa was9. 05%,but the transfer rates of magnolol and honokiol were decreased compared with the condition of1. 5 MPa. The results indicated that high extraction rate of magnolol and honokiol was obtained within a short period of time under the condition of high temperature and high pressure. The higher the pressure of steam processing extraction,the greater the yield of each component,but with the increase of pressure the extracted component may change chemically.
