目的:优选葛参丸的最佳水提工艺,并对提取液的干燥方式进行考察。方法:以葛根素的提取量为评价指标,以溶媒用量、提取次数和提取时间为考察因素,采用L9(34)正交试验优选葛参丸的最佳水提取工艺,并对提取液的不同干燥方法进行比较优选。结果:最佳水提取工艺为加入10倍药材量的水,提取3次,每次1.5h;干燥工艺以喷雾干燥为优。结论:优选的工艺合理可行。
Objective: To optimize the best water extraction technology of GeShen pill and investigate the drying method of extract. Methods: Taking the extraction amount of puerarin as the evaluation index, taking the amount of solvent, the number of extraction and the extraction time as the investigation factors, the optimal water extraction process of Geshe Pills was optimized by L9 (34) orthogonal test. Drying methods are more preferred. Results: The best water extraction process was to add 10 times the amount of medicinal water, extracted three times, each 1.5h; drying process to spray-drying is excellent. Conclusion: The preferred process is reasonable and feasible.
