摘要
目的:提取香附的有效部位并研究其不同有效部位的化学成分。方法:采用超临界CO2萃取技术从香附药材中提取香附超临界CO2萃取物(香附-SFE),再用分子蒸馏技术对香附-SFE作进一步处理,从而富集有效成分。并使用气质联用技术对香附超临界CO2萃取物及分子蒸馏处理所得到有效部位的化学成分分别进行了分析。结果:香附-SFE分子蒸馏前后挥发油的含量由43.2%上升到86.0%,香附子烯和α-香附酮的相对含量由20.2%提高到38.6%。香附-MD1中未检测到脂肪酸类组分。结论:分子蒸馏技术可对香附-SFE进一步精制,有效保留挥发油和α-香附酮等有效成分,去除脂肪酸类等无效成分。
Objective ： To extract the effective part of Rhizoma Cyperi and study the chemical constituents of diffrent parts. Methods： The extract of Rhizoma Cyperi was obtained by SFE and dealed with molecular distillation, then the effective components was enriched, The chemical compositions were separated and identified by GC/MS. Results： The content of volatile oil in the extract upgraded from 43, 2% to 86, 0% by molecular distillation, and the relative amount of cyperene and （ ＋ ） -α-cyperone from 20. 2% to 38.6%. Fatty acids was not found in Rhizoma Cyperi-MD1. Conclusion： The SFE of Rhizoma Cyperi could be refined with molecular distillation. The active ingredients, such as volatile oil and α-cyperolone, were remained effectively. The ineffective ingredients fatty acids were removed,
