Analysis of differences of volatile substances in female flowers of two arecanut germplasms by GC-IMS
In order to study the differences of volatile substances in the flowers of different betelnut plants,headspace-gas chromatography-ion mobility spectroscopy(GC-IMS)technology was used to construct the fin-gerprint of volatile components of two kinds of female flower arecanut germplasms(common white flowers and newly discovered yellow flowers).The differences in composition and relative content of volatile components between the two kinds of areca female flowers were analyzed.The results showed that 72 volatile flavor com-pounds were detected in betel nut female flowers.The differences in volatile flavor substances contents of two female flowers were mainly in alcohols and esters.The contents of alcohol 5.2,acetoin and isobutanol in fe-male flower of yellow flower betel germplasm were three times higher than those of in white flower betel.The relative content of esters in female flower of white flower betel was 2.3 times that of yellow flower betel,mainly ethyl acetate,methyl acetate and isomyl acetate.The relative contents of cis-3-hexenyl acetate,ethyl lactate,hexyl acetate and methyl butyrate were higher in white flower betel than those in yellow flower betel.Female flower of these two betel germplasms could be distinguished with volatile flavor substances by similari-ty and principal component analysis.
