摘要

目的优选山茱萸超临界CO

萃取条件及萃取物GC-MS分析。方法采用正交试验，考察萃取压力、萃取温度、CO

流量和时间四因素对山茱萸超临界CO

萃取物得率的影响并对萃取物成分进行GC-MS分析。结果 ①CO

萃取的最佳条件为：萃取压力35 MPa，萃取温度50 ℃ ，CO

流量20 L／h，萃取时间2 h。GC-MS共分离出72个峰，鉴定了其中32种物质，占总组分的84.27％.主要成分为棕榈酸、9，12-十八碳二烯酸、9-十八碳烯酸及其相关酯类。结论优选了山茱萸超临界CO

萃取条件并对萃取物进行了GC-MS分析。

Abstract

Objective To optimize the extraction condition for volatile components of Cornus officinalis by orthogonal test and analyze the extract by GC-MS． Methods Four factors were chosen in this experiment

including extractive pressure

extractive temperature

flowing rate and time. The extractive components were analyzed by GC-MS. Results The optimal extraction conditions were: pressure at 35 MPa， heating temperature at 50 ℃，being 20 L／h and extracting for 2 h．Seventy-two peaks were isolated and 32 components were identified．The major components identified in the extractions were n-hexadecanoic acid

12-octadecadienoinoc acid and 9-octadecenoic a

cid

etc.. Conclusion This method established to optimize the extraction condition of volatile components of Cornus officinalis and analyze the extract by GC-MS.
