摘要

目的: 研究藏药甘扎嘎日二氧化碳超临界流体萃取精油的化学组成及相对含量。方法: 采用气相色谱-质谱联用方法分离鉴定甘扎嘎日二氧化碳超临界流体萃取精油化学成分并测定其相对含量。结果: 甘扎嘎日二氧化碳超临界流体萃取精油得率为3.08%

分离得到47个色谱峰

鉴定出40种成分

主要成分是四十四烷(30.63%)、三十六烷(20.15%)、二十八烷(16.27%)、DL-α-生育酚(8.39%)、二十七烷(6.29%)、亚麻酰氯(1.87%)和石竹烯(1.64%)等。结论: 二氧化碳超临界流体萃取精油是藏药甘扎嘎日的药效组分之一。

Abstract

Objective: To analyze the chemical constituents of the essential oil from Rubus amabilis extracted by supercritical CO2 and determine their contents. Method: The essential oil from R. amabilis were extracted by supercritical CO2

and the chemical constituents were identified and their relative content was determined by GC-MS. Result: The yield of essential oil was 3.08%. 47 peaks were separated by GC-MS

and 40 components were identified. The main constituents were tetratetracontane (30.63%)

hexatriacontane (20.15%)

octacosane (16.27%)

DL-α-tocopherol (8.39%)

heptacosane (6.29%)

lineoleoyl chloride (1.87%) and caryophyllene (1.64%). Conclusion: The essential oil extracted by supercritical CO2 was one of the effective components of Rubus amabilis.
