摘要: 用固相微萃取装置(SPME)提取圆黄梨和黄金梨香气成分,用GC-MS法从中分离并确认化学成分,用峰面积归一法通过G1701BA化学工作站数据处理系统得出各化学成分在香气成分中的百分含量。结果表明,从圆黄梨中检测鉴定出7种化学成分,分别为:乙酸乙酯、乙醇、α-法呢烯、己酸乙酯、丁酸乙酯、辛酸乙酯和2-甲基-丁酸乙酯。从黄金梨中共检测鉴定出6种化学成分,分别为:乙酸乙酯、乙醇、α-法呢烯、己酸乙酯、丁酸乙酯和2-甲基-丁酸乙酯。

Abstract: The essential substances from Yuanhuang pear and Whangkumbae pear were obtained by using solid phase microextraction (SPME) respectively,and their chemical components were separated and identified by GC-MS respectively. The experimental results demonstrate that the main aromatic components of Yuanhuang pear are ethyl acetate,ethanol,alpha-farnesene,hexanoic acid,ethyl ester,butanoic acid,ethyl ester,octanoic acid,ethyl ester and butanoic acid,2-methyl,ethyl ester. The aromatic main components of Whangkumbae pear are ethyl acetate,ethanol,alpha-farnesene,hexanoic acid,ethyl ester,butanoic acid,ethyl ester and butanoic acid,2-methyl,ethyl ester.

Key words: Yuanhuang pear, Whangkumbae pear, essential substance, solid phase microextraction, GC-MS
