【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。更多还原

【Abstract】 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.更多还原
