【摘要】 利用顶空固相微萃取法提取芳香物质,气相色谱-质谱联机定性定量分析,测定曹州木瓜狮子头、剩花、豆青和玉兰的挥发性物质,并对木瓜不同品种的香气组分进行分析探讨。共测定出145种香气组分,曹州木瓜狮子头、剩花、豆青和玉兰分别为70、70、69和70种,各自占总峰面积的99.88%、99.7%、99.97%、99.37%,以醇类、醛类、烯烷类、酮类、酯类、杂环类等为主,其中又以C6醇(如1-己醇、2,4-己二烯-1-醇、反式-2-甲基-环戊醇等)、C6醛[(E)-2-己烯醛、2-己烯醛、E,E-2,4-己二烯醛等]居多。结果表明:狮子头、剩花、豆青和玉兰不同品种香气组分存在一定的差异,但大部分主要组分相同;主要组分含量差异是曹州木瓜不同品种间香气不同的主要原因。更多还原

【Abstract】 The aromatic substances in the fruit of Chaenomeles sinensis (Shizitou,Shenghua,Douqing and Yulan cultivars)in Caozhou,Shandong,China were determined by using headspace solid phase microextraction and GC/MS. Differences of aromatic substances among four cultivars were analysed. The results showed that total 145 kinds of substances were detected,in which there were 70 kinds in Shizitou,Shenhua and Yulan respectively,and 69 kinds in Douqing. The relative content was 99.88%,99.7%,99.37%,99.97% respectively. The main aromatic substances in Chaenomeles sinensis in Caozhou were alcohols,aldehydes,alkyls,ketones,esters,mixed cycloes,and the alcohols with six C(1-Hexanol,2,4-Hexadien-1-ol,trans-2-methyl-Cyclopentanol) and the aldehydes with six C ((E)-2-Hexen-1-ol,2-Hexenal,(E,E)-2,4-Hexadienal) were the main substances.The results indicated that aromatic substances in four different cultivars were different,but most main compositions were the same. The difference of the main aromatic substances was the main cause of the different aroma of the Chaenomeles sinensis in Caozhou.更多还原
