摘要:以迷迭香叶为原料,采用超声波辅助乙醇提取、超声波辅助正己烷提取及p H值调节、硅胶柱层析3步骤复合提取纯化方法制备鼠尾草酸,结果表明:迷迭香叶经超声波辅助乙醇提取得到迷迭香叶提取物,其鼠尾草酸纯度为21.06%;迷迭香叶提取物经超声波辅助正己烷提取和p H调节得鼠尾草酸粗品,其鼠尾草酸纯度为79.62%,超声波辅助正己烷提取的优化条件为:液固比20∶1(m L∶g)、超声波频率28 k Hz、超声波时间40 min、超声波功率140 W,鼠尾草酸的得率为2.0%;硅胶柱层析的优化条件为:硅胶粒径48~75μm、洗脱剂为乙酸乙酯/石油醚(体积比4∶7)、洗脱剂流速6 m L/min、上样量为0.3 g,鼠尾草酸回收率为54.12%。通过此种方法得到的鼠尾草酸纯度为95.18%。
Using the composite method of the following three steps to get carnosic acid from rosemary leaves,the purity of carnosic acid was 21. 06% by ultrasound-assisted ethanol extraction. The purity of carnosic acid was 79. 62% by ultrasonic-assisted n-hexane extraction and p H adjustment. The optimization conditions of ultrasonic-assisted n-hexane extraction were liquid / solid ratio 20 ∶ 1( m L ∶ g),ultrasonic frequency 28 k Hz,ultrasonic time 40 min,ultrasonic power 140 W. Under these conditions,the yield of carnosic acid was 2. 0%. The optimization conditions of silica gel column chromatography were particle sizes of silica gel48- 75 μm,the volume ratio of eluent ethyl acetate and petroleum ether 4 ∶ 7,the flow rate 6 m L / min and 0. 3 g solid loaded.The recovery rate of carnosic acid was 54. 12%. The purity of carnosic acid was 95. 18% by this method.
