不同种源高良姜1,8-桉油精含量及挥发油成分分析

Composition Analysis on 1,8-Cineole and Volatile Oil in Alpinia officinarum Hance from Different Regions

目的:对不同种源高良姜1,8-桉油精及挥发油化学成分进行分析,为高良姜优良种源的选择及品种选育奠定基础。方法:采用水蒸汽蒸馏法提取高良姜药材中挥发性化学成分,采用气相色谱-质谱技术(GC-MS)对其化学成分进行分离鉴定。结果:野生及人工栽培高良姜药材1,8-桉油精含量均达到《中国药典》要求;人工栽培药材1,8-桉油精含量随着栽培年限的延长而增加;从挥发油中共分离鉴定28种化合物,含量较高的主要为L-α-松油烯、反式-石竹烯、γ-杜松烯、1,8-桉油精、法尼烯等成分。结论:不同种源不同生长年限高良姜1,8-桉油精含量及挥发油成分存在较大差异。

Objective：The content of 1,8-cineole and volatile oil in Alpinia officinarum Hance from different regions was analyzed, which laid the foundations for selecting and breeding of seed sources.Method：The steam distillation was used for the extraction and GC-MS was applied for the separation and elucidation of volatile constituents in A.officinarum Hance.Results：The content of 1, 8-cineole both in wild and cultivated drugs was up to the criterion recorded in Chinese pharmacopoeia.Furthermore, the content of 1, 8-cineole in the cultivated ones increased along with the vegetation periods.Twenty-eight compounds were isolated and elucidated, and the content of L-α-terpinene, trans-caryophyllene, γ-cadinene, 1,8-cineole, farnesene was relatively higher.Conclusion：It was shown that the regions and growth periods played very important role at the content of 1, 8-cineole and volatile oil in A.officinarum Hance.
