The experimental conditions were as follows: Ultrasphere ODS column (250 mm 4.6 mm, 5 mm), mobile phase: acetonitrile-water (containing 1.0% acetic acid) (20:8050:50) (20 min), flow-rate 1 mLmin-1, room temperature, detection wavelength 278 nm. Twenty-eight samples of Xuan-shen (Radix Scrophulariae) from different districts of China were analyzed and the contents of harpagoside and cinnamic acid in Xuan-shen were 0.041~0.244% and 0.012~0.068% respectively. The recoveries (RSD)% were 97.13(0.80)% for harpagoside and 99.38(0.51)% for cinnamic acid. The method is simple and accurate. It can be used for the quality control of Radix Scrophulariae. We propose that the content of harpagoside in qualified Radix Scrophularia should be no less than 0.05%.展开更多

Due to characteristics of multi-component, multi-efficacy, multi-target, the existing quality evaluation system still cannot fully meet quality control needs of CMM. Hence, the author put forward “Bio-characteristic profiling related to clinic, BPRC” academic concept, meanwhile, fully take the advantage of analysis method with clinical monitoring superiority or profiling characteristics, build up “BPRC” new technology platform, in order to realize “real-time, dynamic and full-range monitoring” new technologies of CMM quality evaluation system and promote the further development of CMM industry.展开更多

Many experts put forward relevant research ideas and methods and worked out more and more research results in literature, experimental and clinical categories because of the progress of statistical methods and scientific and technological means in recent years. In this paper, these results were preliminarily combed to show the basic situation of dose-effect relationship research in Chinese materia medica.展开更多
