Comparative study on standard decoctions of Ophiopogonis Radix and Liriopes Radix / 中国中药杂志

ABSTRACT

Standard decoction is the core of the pharmacodynamics for water-soluble substance of Chinese materia medica. Its research is of great significance to the research and development of some single ingredients and the classical prescriptions,and it is the only way to transform traditional medication experience into industrial products. In this article,standard decoction research strategies were used for the comparison analysis of Ophiopogonis Radix from Zhejiang province(ZMD),Ophiopogonis Radix from Sichuan province(CMD),and Liriopes Radix(SMD). Regularities were present among different grades of CMD; potential quality markers and pH differences associated with SO2 residues were also found. Finally,the extract powder of Ophiopogonis Radix prepared by mass production process was analyzed and validated,and the results showed that the standard system could be used for the quality control of intermediates and final products. In conclusion,this study can provide reference for the clinical application of Ophiopogonis Radix medicines and provide testing method for higher quality with higher price.
