摘要:

目的:研究不同生长期、不同部位和不同海拔区密花香薷挥发性成分。方法:采用水蒸气蒸馏法提取密花香 薷挥发油,以气相色谱进行分析、归一化法测定其相对含量,并用气相色谱-质谱法对化学成分进行鉴定。结果:密 花香薷的花和叶是释放挥发性成分的主要部位,始花期和盛花期是释放挥发性成分的主要时期,其挥发性成分含量随 海拔升高有逐渐增大的趋势。盛花期密花香薷全草中主要挥发性成分为:烯类34.57%,醇类17.17%,酚类14.68%,酸 类9.91%,烷烃类9.52%,醛、酯、芳烃、醚类5.44%,而不同生长期、不同部位和不同海拔地区各挥发性成分的相对 含量不同。结论:本研究为密花香薷的科学采集和有效开发利用及质量标准的制订提供了参考依据。

Abstract:

Purpose: To analyze volatile components in various parts of Elsholtzia densa at various growth stages and various
altitude areas. Methods: The volatile oil of Elsholtzia densa was extracted by steam distillation method. The identification
was performed by gas chromatography-mass spectrometry (GC-MS) and the quantification was conducted by GC using
peak area normalization method. Results: The flowers and leaves of Elsholtzia densa were the major parts where volatile
components were emitted. The early flowering and full bloom stages were the major periods for the emission of volatile
components. In addition, there was an increasing trend of volatile components contents with the increasing altitude where
Elsholtzia densa was grown. It was found that the major volatile components in Elsholtzia densa were identified to be
alkenes (34.57%), alcohols (17.17%), phenols (14.68%), acids (9.91%), alkanes (9.52%), aldehydes, esters, aromatic
hydrocarbons and ethers (5.44% in combination). Their contents varied with growth phases, parts and altitudes. Conclusion:
This study has provided a scientific basis for scientific collection, effective development and use of Elsholtzia densa as well
as the formulation of quality standards.
