气相色谱质谱联用法分析滇姜花挥发油化学成分

Determination of Volatile Oil of Hedychium yunnanense Gagnep.by Gas Chromatography-Mass Spectrography

为了研究滇姜花挥发油的化学成分,本试验采用水蒸气蒸馏法从滇姜花的花中提取挥发油,用气相色谱-质谱联用仪对其进行分离测定,通过HPMSD化学工作站检索,对分离的化合物进行结构鉴定,应用色谱峰面积归一化法测定各成分的相对百分含量,鉴定出了29个化学成分。其中主要成分为(2E,6E)-3,7,11-三甲基-9-苯磺酰-2,6,10-十二烷基三烯-1-醇、(1R)-(+)-α-蒎烯、莰烯、桧烯、乙酸1,7,7-三甲基二环[2.2.1]-2-庚酯、α-石竹烯、(E)-β-金合欢烯、2-茨醇,其含量分别为20.636%,5.913%,4.128%,3.964%,2.046%,1.786%,1.737%,1.568%。这些成分可能是滇姜花的主要释香成分。

To study chemical constituents from the flowers of Hedychium yunnar^ense Gagnep. , the es- sential oil were obtained by steam distillation. The chemical constituents in essential oil were separated and identified by GC -MS and HPMSD Chemstation analysis, and their relative contents were deter- mined by the method of area normalization. As a result, twenty-nine compounds together with their contents were determined. Among them, （2E, 6E） -3, 7, 11-trimethyl-9- （phenylsulfonyl） -2, 6, 10-dodecatrien-l-ol, （1R） - （＋） -α-pinene, camphene, sabenene, 1, 7, 7-trimethyl-bicyclo [ 2.2. 1 ] heptan-2-α-2-acetate, （x-caryophyllen, （E） -β-farnesene and borneol were the major com- ponents. The contents of them were 20. 636%, 5. 913%, 4. 128%, 3.964%, 2. 046%, 1. 786%, 1. 737%, 1. 568%, respectively. These compounds with relatively higher content might be the mainly characteristic aroma components of H. yunnanense. K
