Analysis of Volatile Organic Compounds

In this study, GC-MS and sensory evaluation were used to analyze the volatile components of fruits 2 white M. rubra purple . Meanwhile, their relationship among each other massion pine ( Pinus massoniana ) detected. The test results showed that, there 60 organic compounds (VOCs) in 8 categories, including aldehydes, acids, ketones, alcohols, esters, phenols, olefins alkanes, found four cultivars. Among which, 32 cv “Biqi”, 25 “Yongjia”. 18 both “Shangyu” “Yewu”. three main different, Yongjia was mainly composed turpentine-4-alcohol, 1-methyl-4-(1-methyl-ethyl) cyclohexene turpentinene, accounting for 53.30%. Yewu caryophyllene, L-turpinol D-limonene, 53.77%. Shangyubaiyangmei pinole-4-alcohol, pinolene, 1,3,8-p-menthotriene, 61.37%. Biqi ethyl acetate o-isopropyl toluene, 73.22%. masson resin α-pinene, camphene, β-pinene, which different with Myrica At same time, ISSR molecular marker analysis bayberry leaves needles that had close Yewu, bayberry, but not Masson's pine. Therefore, it is suggested aroma fruit may be characteristic expression form evolutionary process, related genetic evolution breeding results, has nothing do
