亚临界流体萃取贡菊净油的方法及其成分分析

摘要

By using Tribute Chrysanthemum as the raw material,Tribute Chrysanthemum oil was extracted by subcritical extraction technology, The absolutes oil components were separated and identified by GC-MS. The results indicated that the yield of the crude oil was 4.6%, The volatile components of Tribute Chrysanthemum oil were ketones of 30.14%,olefins of 21.80%, alcohols of 11.80%, acids of 11.18%,esters of 10.72%,aldehydes of 1.78%, others of 12.58%.%以黄山贡菊为原料，采用亚临界流体萃取技术，萃取贡菊中的油类成分，所得到的贡菊净油进行GC/MS检测分析。结果表明，亚临界流体 DME萃取贡菊净油的粗品得率为4.6%，贡菊净油挥发性成分中酮类物质占30.14%，烯烃类物质占21.80%，醇类物质占11.80%，酸类物质占11.18%，酯类物质占10.72%，醛类物质占1.78%，其他物质占12.58%。
