摘要
研究了从天竺桂叶中提取精油的方法,并对其精油的成分进行分析。以天竺桂叶为研究材料,用水上水蒸汽蒸馏法提取天竺桂精油,并用GC-MS(气相色谱-质谱联用技术)对其组成成分进行分析。结果表明:提取时间以4 h为宜,精油得率为0.42 mL/100 g;天竺桂叶精油中鉴定出了57种物质,相对含量最高的成分为2-羟基-1,7,7-三甲基降冰片烯(18.55%),其它依次为(-)-柠檬烯(7.68%)、乙酸冰片酯(7.55%)、l-石竹烯(7.34%)等。
The methods for extracting essential oil from the leaves of Cinnamomum edunculatum were studied, and the chemical components were analyzed. The leaves of C. edunculatum were cut to pieces, the essential oil was extracted out by on-water water vapor distillation method. The tests results indicate that the optimal extraction time was 4 hours, the yield of essential oil was 0.42 mL/100g. The oil extracted has been analyzed with GC-MS, and results show that there are 57 kinds of chemical materials, of them, the components with highest relative contents of essential oil were Bicyclo[2.2.1]heptan-2-ol, 1,7,7-trimethyl-（18.55%）, （-） - limonene （7.68%） , bornyl acetate （7.55%）, and 1- caryophyllene （7.34%）.
