摘要: 目的:研究微波法提取玉竹总皂苷的最佳工艺条件。方法:以玉竹提取干浸膏中总皂苷的含量为评价指标,采用单因素和正交试验法对微波法提取玉竹总皂苷的工艺条件进行优化。结果:确定玉竹总皂苷微波提取的最佳工艺条件为乙醇体积分数50%、微波提取时间10min、料液比1:20(g/mL)、提取次数3次、微波功率400W,该条件下提取的玉竹总皂苷的平均含量为5.414mg/g。结论:优选得到的微波提取工艺简单易行,稳定性好。

Abstract: Objective: To optimize conditions for the ethanol extraction of total saponins (TS) in Rhizoma Polygonati odorati with the assistance of microwave. Methods: The optimization of extraction conditions was performed by single factor and orthogonal array design methods based on TS content of extracts. Results: The optimal extraction conditions were obtained as follows: ethanol concentration 50%, material-to-liquid ratio 1:20 (g/mL) and microwave power 400 W for extraction repeated times for 10 min each time. The average content of TS in dry extracts was 5.414 mg/g under the optimum extracting condition. #br# Conclusion: The optimized extraction process is simple and easy to operate and has good stability.
