摘要:

采用加热回流提取法、超声波辅助提取法、微波辅助萃取法和超临界CO2 流体提取等技术从厚朴枝中提取厚朴酚及和厚朴酚,优化提取条件,用反相高效液相色谱法(RP-HPLC)测定厚朴酚及和厚朴酚的提取得率,比较不同提取方法对厚朴枝中厚朴酚及和厚朴酚的提取效果。结果表明,微波辅助提取厚朴枝中厚朴酚速度最快,当微波功率为低火(1~2.8PV,200W)、乙醇体积分数65%、料液比1:40(mg/mL)、提取时间10min 时,单次提取得率最高,厚朴酚与和厚朴酚及总酚得率分别为7.893mg/g 和1.938mg/g。

Abstract:

Heat reflux, ultrasonic-assisted extraction, microwave-assisted extraction and supercritical carbon dioxide extraction were compared for extraction of magnolol and honokiol from branches of Megnolia Hypoleuca. Reverse-phase HPLC was used for quantitative analysis of magnolol and honokiol. Results showed that among four extraction techniques, the least time was consumed for the microwave-assisted extraction of magnolol and honokiol, and the single microwave-assisted extraction for 40 min at 200 W (1-2.8 PV) with 65% ethanol as extraction solvent using a material/liquid ratio of 1:40 (mg/mL) gave the highest yields of magnolol and honokiol, which were valued at 7.893 mg/g and 1.938 mg/g, respectively.

Key words: magnolol, honokiol, extraction technology, high-performance liquid chromatography
