摘要
采用动态顶空套袋采样法和TCT-GC-MS联用技术,对峨眉箬竹竹叶挥发性成分进行采集、鉴定及分析,共获得40个色谱峰,鉴定了其中40种成分,其中(z,z)-9,12-十八酸二烯甲酯含量最高、为27.23%;其次为13-二十二烯酸甲酯(13-三嵛烯酸甲酯),含量为18.25%。在40种成分中,有酯类15种、醇类6种、醛类8种、酸类8种、酮类2种、烯类1种,含量分别占挥发性成分总量的84.13%、7.28%、4.65%、3.40%、0.42%和0.12%。
Using the dynamic headspace bagging sampling and TCT-GC-MS analysis method, the volatile composition of lndocalamus emeiensis leaves was extracted, separated and identified. A total of 40 chromatographic humps were obtained, identified 40 kinds of component, in which 9,12-Octadecenoic acid （z,z）-methyl ester was the composition with the highest content of 27.23% and 13-Docosenoic acid methyl ester with the second highest content of 18.25%. Among 40 kinds of composition, there were 15 ester compounds, 6 alcohol compounds, 8 aldehydes compounds, 8 acid compounds, 2 ketone compounds and 1 olefine compounds, according for 84.13%, 7.28%, 4.65%, 3.40%, 0.42% and 0.12% of total volatile composition resnectivelv.
