The study was designed to explore the potential applications of the real-time cell electronic analysis technology in the quality evaluation of natural medicines.The natural medicinal Flos Carthami was discussed as a methodological example and the specifc time/dose-dependent cell response profles(TCRPs)were produced by the real-time cell electronic analysis technology.The similarity and bioactivity were obtained by analyzing all TCRPs.Meanwhile,an HPLC method according to the Chinese Pharmacopeia(edition 2010)was used to evaluate the quality of Flos Carthami.The correlation was obtained by comparing the results produced by the two different approaches.By analyzing the data,fve different samples of Flos Carthami can produce remarkably similar TCRPs.The quality of Flos Carthami was evaluated by both the HPLC and the TCRPs analysis-based approaches and similar results were obtained.The results suggest that the same natural medicine from different locations could produce similar TCRPs.By analyzing the TCRPs,the bioactivity and quality evaluation of natural medicines can be obtained.This technology is a physiologically relevant approach for the quality evaluation of natural medicines.The ultimate aim of our study is to establish a new standard for quality evaluation.
The study was designed to explore the potential applications of the real-time cell electronic analysis technology in the quality evaluation of natural medicines. The natural medicinal Flos Carthami was discussed as a methodological example and the specifc time / dose-dependent cell response profles (TCRPs ) were produced by the real-time cell electronic analysis technology. The similarity and bioactivity were obtained by analyzing all TCRPs.Meanwhile, an HPLC method according to the Chinese Pharmacopeia (edition 2010) was used to evaluate the quality of Flos Carthami. correlation was obtained by comparing the results produced by the two different approaches. By analyzing the data, fve different samples of Flos Carthami was remarkably similar similar to TCRPs.The quality of Flos Carthami was evaluated by both the HPLC and the TCRPs analysis-based approaches and similar results were obtained.The results suggest that the same natural medicine from different locations could be similar to TCRPs.By an alyzing the TCRPs, the bioactivity and quality evaluation of natural medicines can be obtained. This technology is a physiologically relevant approach for the quality evaluation of natural medicines. The ultimate aim of our study is to establish a new standard for quality evaluation.
