正交试验法优选通络颗粒剂的提取工艺

目的优选通络颗粒剂的提取工艺。方法采用正交试验法,分别对水提部分和醇提部分进行提取工艺考察。水提部分,以提取次数、加水量、提取时间为考察因素,以芍药苷含量和浸出物重量为指标;醇提部分,以乙醇浓度、提取次数、溶剂用量、提取时间为考察因素,以橙皮苷含量和浸出物重量为指标,对提取工艺方案进行优选。结果优选的提取工艺为:水提部分,处方药材用12倍药材量的水煮提3次,每次1.5h;醇提部分,加10倍药材量的60%乙醇回流提取2次,每次1.5h。结论最佳提取工艺的确立为通络颗粒剂的生产提供了理论上的依据。

Optimization on Extracting Technology of Tongluo Granule by Orthogonal Design

Objective To optimize an extracting technology for Tongluo granule by orthogonal design. Methods Water-extracting fraction:with the weight of water-extracting fraction and paeoniflorin content as the indexes,extracting times,water volume and extracting time were screened by L9(34) orthogonal test,Alcohol-extracting fraction:with the weight of alcohol-extracting fraction and hesperidin content as the indexes,alcohol concentration,extracting times,alcohol volume and extracting time were screened by L9(34) orthogonal test. Results The optimal extraction conditions were as follows:water-extracting fraction: extracting 3 times with 12-fold water,1.5 hours for each time;alcohol-extracting fraction:refluxing and extracting 2 times with 10-fold 60% alcohol,1.5 hours for each time. Conclusion The results can provide theoretical basis for production of Tongluo granule.
