GC-MS分析大莪术根茎挥发油成分

Analysis of Volatile Oil in Rhizome of Curcuma elata by GC-MS

文章分析了大莪术根茎挥发性成分,并探究不同加工方法对其成分的影响,为大莪术的加工工艺筛选和进一步的研究开发提供实验依据。利用冷冻干燥和真空干燥处理新鲜的大莪术根茎样品,采用水蒸气蒸馏法提取大莪术挥发油,应用GC毛细管柱进行分离、质谱检测、面积归一化法测定相对含量,分析其挥发性化学成分。由于不同干燥方法加工大莪术根茎挥发油的组分绝大部分相同,但是相对含量存在一定差异。实验证明,大莪术根茎主要含有表莪术呋喃烯酮、β-榄香烯、β-桉叶醇、吉马酮、莪术双环烯酮、蓬莪术环氧酮、莪术烯、β-石竹烯等挥发性成分,均具有一定的生理活性,具有广泛的开发前景。

In this paper,the volatile components of rhizome of Curcuma elata were analyzed,and the effects of different processing methods on the components were explored,which provided experimental basis for the processing technology screening and further research and development of Curcuma elata.The volatile oil was extracted by steam distillation from fresh rhizome samples of Curcuma elata by freeze-drying and vacuum drying.The relative content was determined by GC capillary column,mass spectrometry and area normalization method,and the volatile chemical components were analyzed.The components of volatile oil in rhizome processed by different drying methods are mostly the same,but the relative contents are different.The results show that the rhizome mainly contains the volatile components of epizurcumenone,β-elemene,β-eudinol,gemarone,curcumenone,curcumenone epoxide,curcumenene andβ-caryophyllene,which have certain physiological activities and have broad development prospects.
