摘要:
 利用GC/MS技术分析了四种石斛兰Dendrobium Nora Tokunaga、Dendrobium Green Lantern、Dendrobium Spider Lily和Dendrobium Little Green Apples花朵的香气成分。结果表明,四种石斛兰香气成分的种类和含量存在明显差异,其中Dendrobium Nora Tokunaga有香气成分15种,相对含量为79.62%;Dendrobium Green Lantern有31种,相对含量94.97%;Dendrobium Spider Lily有88种,相对含量87.45%;Dendrobium Little Green Apples有79种,相对含量8949%。烯烃类、醇类和醛类三类化合物占四种石斛兰挥发物总量的63.33%、81.64%、70.47%和66.31%。己醛、2己烯醛和丁羟甲苯是四种石斛兰共有的主要香气成分,石竹烯是Dendrobium Green Lantern和Dendrobium Spider Lily的特征香气成分,Dendrobium Little Green Apples的苹果香气可能来源于花朵中乙酸乙酯的果香气息。
Abstract:
 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.
