Abstract:

To assess volatile variety of mango germplasm，composition and relative content of volatile in 28 mango cultivars were investigated by using solid phase micro-extraction headspace GC–MS methods. The results showed that there were significant differences among the cultivars in composition and relatively content of volatile. Totally 63 volatiles belonging to various chemical classes were detected. Based on the cumulative occurrence of members of these classes，cultivars were grouped as terpene，esters or aldehydes dominant. Terpene hydrocarbons were the major volatiles of 24 cultivars，the dominant terpenes being 3-carene，terpinolene and α-cubebene depending on different cultivars. The highest concentration of esters were found in‘Lippens’，‘Guixiang Mang’and‘Yingwu Mang’，the dominant esters of the three cultivars being butyl butyrate，2-methylbutyl butyrate and ethyl isovalerate，respectively. 6-Bromoindole-3-carboxaldehyde was the major aldehyde in‘Fengshun Wuhe’，which accounted for 33.64% of the total flavor volatile compounds.
