ABSTRACT
Objective To investigate the optimal extraction process of Jiangtang Tongluo Granule. Methods The orthogonal design was used in the extraction, according to the yield rate and content of paeoniflorin, with the volume of water, extraction times and extraction time as factors. The content of paeoniflorin was detected by HPLC method to determine the best extraction technology. Results The optimal water extracting technology of Jiangtang Tongluo Granule was performed by 1 h extraction for 3 times, with 10-fold volume of water. Conclusion The process is stable, feasible and reasonable, and provides a foundation for the further production and quality control.
ABSTRACT
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.
