Abstract:

Aroma components in fresh flowers from 6 germplasm of Robinia neo-mexicana var. LuxuriansR. viscosaR. pseudoacacia‘Ziyan Qingshan’,R. pseudoacacia‘Duocai Qingshan’,L2F and L68F were analyzed by Micro-extraction and GC–MS technology. The results showed that:(1)Fifty-three kinds of volatile compounds were identified in fresh flowers from 6 cultivars of genus Robinia,mainly including terpenes,alcohols,esters,ketones,aldehydes,arenes and alkanes. Flowers aromatic components of the 6 samples consist of terpenes,alcohols and esters. The relative amount of components was as follows:terpene > alcohol > esters. Terpene is the main aroma components.(2)The highest content of terpenes and alcohols of red flowers of R. neo-mexicana var. luxurians and R. viscosaare (E)-4,8- dimethylnona-1,3,7-triene, 1-octen-3-ol. The highest content of terpenes and alcohols from the rest 4 samples with white flowers are beta-ocimene,linalool.(3)According to the relative content and type of volatile matter,we defined the flowers fragrance of R. neo-mexicana var. luxurians and R. pseudoacacia ‘Duocai Qingshan’as light flavor,,R. pseudoacacia‘Ziyan Qingshan’,L2F and L68F as strong flavor.
