摘要
目的:优选黄芩汤的提取工艺。方法:以方中黄芩苷含量、芍药苷含量和干膏率为指标,采用L9(34)正交试验法,优化黄芩汤的提取工艺。结果:黄芩汤最佳提取工艺为加水量为其处方量药材的10倍,煎煮3次,每次1 h。结论:该工艺稳定可行,重现性良好。
Objective:To optimize the extraction process of Huangqin Decoction. Methods:Using the orthogonal design, the content of ba- icalin,paeoniflorin and the dried decocting rates were selected as indexs to optimize the extraction process of Huangqin Decoction. Re- suits:The best extraction process of Huangqin Decoction was obtained as following :10 times of water, extraction for 3 times and 1 hour for each time. Conclusion:The optimized process is stable and good reproducibility.
