摘要
应用具有压力控制附件的 MSP- 10 0 D密闭微波萃取装置 ,对丹参中的有效成分丹参酮 、丹参酮 A及隐丹参酮进行微波萃取研究 .在乙醇体积分数为 90 % ,微波辐射时间为 4 m in,溶剂体积对样品质量比为2 0∶ 1和样品粒径为 12 0目的条件下 ,有效成分提取率最佳 .对比了密闭微波萃取同索氏萃取和超声萃取丹参有效成分的差异 .
A microwave-assisted extraction procedure was developed for transhinone Ⅰ, transhinone ⅡA and cryptotranshinone in Chinese herbal medicine Salvia mltiorrhiza Bunge, using an obturated microwave-assisted extraction device with a pressure controlling part. The effects of the solvent consistence, solid/liquid ratio, the microwave radiation time and sample particles on the leached output was studied. Compared with Soxhlet extraction and ultrasonic extraction, microwave-assisted extraction is more efficient.
