摘要：利用GC/MS技术分析了四种石斛兰DendrobiumNora Tokunaga、DendrobiumGreen Lantern、Den-drobiumSpider 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DendrobiumNora Tokunaga有香气成分15种,相对含量为79.62%;Den-drobiumGreen Lantern有31种,相对含量94.97%;DendrobiumSpider Lily有88种,相对含量87.45%;DendrobiumLittle 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DendrobiumGreen Lantern和DendrobiumSpider Lily的特征香气成分,DendrobiumLittleGreen Apples的苹果香气可能来源于花朵中乙酸乙酯的果香气息。
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.
