Abstract:

In order to screen the potential aromatic cultivars for industrial application,the volatile components of the flowers in 20 Wisteria sinensis cultivars were detected by headspace solid phase microextraction combined with gas chromatography-mass spectrometry. The results showed that there were significant differences of volatile aroma components between different cultivars. A total of 96 volatile compounds were detected,and the fatty acids and their derivatives were proved to be the dominant aroma compounds due to their highest types and contents. The odor activity values(OAVs)and principal component analysis were integrated to reveal that 1-octen-3-one,hexanal,1-hexanol and trans-2-hexenal with high OAVs imparted the unique sweet grass note to flowers in many cultivars. In addition,D-limonene,indole,and phytol acetate were also important aroma compounds with woody and tea notes,causing different olfactory senses in different cultivars.‘Zhaohe Baiteng’‘Zhaohe Hongteng’‘Yinteng’achieved high aroma contents,while‘Shexiangteng’‘Kouhongteng’and‘Zhaohe Baiteng’were the most preferred cultivars. They had outstanding sweet,floral and tea aroma,and were considered as excellent materials for extracting aromatic compounds. The determination of aroma compounds in‘Zhaohe Baiteng’demonstrated that the full blossoming period was the ideal harvest period.
