摘要:
利用气相色谱 质谱联用仪对新鲜罗汉果的乙醚萃取物的风味成分进行分析,并结合计算机检索对其化学成分进行分析和鉴定,结果显示:从新鲜罗汉果风味物质中分离出42个组分,并鉴定出其中的26个化合物,占风味挥发油色谱峰面积的83.69%。用气相色谱峰面积归一化法测定了各组分的相对质量分数,新鲜罗汉果风味挥发油中相对质量分数较高的成分分别是2 甲基 2 丁酸丁酯(30.76%)、2,4 乙酰氧戊烷(1105%)、2 庚醇(10.58%)、乙酸丁酯(4.93%)、正己醇(3.81%)、醋酸仲丁酯(3.05%)。

Abstract:
The constituents of volatile oil from the tubers of Siraitia grosvenorii were analyzed by GC MS. About 42 components were separated and 26 compounds were identified,accounting for 83.69% of the total contents. The major components are:2 Butenoic acid,butyl ester(30.76%),2,4 Diacetoxypentane(11.05%),2 Heptanol(10.58%),Acetic acid,butyl ester(4.93%)、1 Hexanol(3.81%),2 butanol acetate(3.05%).
