GC-MS analysis on aroma components in four Dendrobium cultivars

The aroma components of four Dendrobium cultivars(Dendrobium Nora Tokunaga,Dendrobium Green Lantern,Dendrobium Spider Lily and Dendrobium Little Green Apples)were analyzed by GC/MS technology.The results showed that there were differences in both aroma components and relative contents among the four Dendrobium cultivars.There were 15 aroma components in Dendrobium Nora Tokunaga,and the relative content was 79.62%.31 aroma components in Dendrobium Green Lantern and the relative content was 94.97%.88 aroma components in Dendrobium Spider Lily and the relative content was 87.45%.79 aroma components in Dendrobium Little Green Apples and the relative content was 89.49%.Alkyl,alcohol and aldehyde were the major compounds,and their relative contents were 63.33%,81.64%,70.47% and 66.31% in the four cultivars respectively.Hexanal,2-hexenal and butylated hydroxytoluene were the major aroma components of the four Dendrobium cultivars,and caryophyllene was the major aroma components of Dendrobium Green Lantern and Dendrobium Spider Lily.The apple odor of Dendrobium Little Green Apples was originated from ethyl acetate probably.
