全叶青兰挥发性成分的研究

采用顶空固相微萃取结合色谱质谱技术分析了全叶青兰中挥发性成分的组成和含量。结果表明：6min和30min的顶空吸附时间所测得的全叶青兰中挥发性成分的组分基本一致，但各组分所占的比例有一定差异。全叶青兰挥发性成分中以萜烯类为主的碳氢化合物约占其总质量分数的50%，醇类化合物占到约20%，其它成分的含量高低依次为酯、酮、萜烯氧化物和醛类化合物，醚、胺及含硫化合物等含量极低。

Study on the Volatile Components from Dracocephalum Integrifolium Bge.

The compositions and contents of volatile components from dracocephalum integrifolium Bge. were analyzed by using headspace solid-phase microextraction (HS-SPME) fixed with gas chromatography-mass spectrometry (GC-MS) method. The results indicate that volatile components were basically identical on the main components for 6 min and 30 min headspace adsorption time except for different proportion. The hydrocarbons (mainly for terpenoids) were gave priority to dracocephalum integrifolium Bge, which account for about 50%, the alcohol compounds for around 20%, others are in order as esters, ketones, terpene oxides and aldehyde compounds, respectively. However, the contents in such as ether, amine and sulfur compound were very low.
