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.
