Abstract:
To study the secondary development of major Chinese materia medica (CMM) varieties is the important content of CMM innovation research, and it is also the important approach of inheriting and developing traditional Chinese medicine (TCM) theory and breaking the bottleneck restricting the development of TCM theory and CMM industry development. In this paper, the secondary development of Liujing Toutong Tablets (LTT) was systematically studied. The chemical components of LTT were elucidated by identification and characterization of herbs, LTT and components ingested into the blood. The main effective components were further screened and cleared by binding experiments of G protein coupled receptors and network pharmacology analysis. The mechanism of LTT was explained by the studies of animal models, isolated organs, cells, functional receptors, and network pharmacology related with headache. The formula features, compatibility regularity were clarified and the action properties, comparative advantages and core clinical value were found and refined by the research of decomposed recipes and the comparison with the similar CMM recipes and chemical drugs. The quality control systems of LTT and related herbs were established by systematic research of identification and characterization of chemical components, the LTT chemical information herbal source, content determination of multi-target ingredients, establishment of the characteristic mode of HPLC fingerprint, sample determination of multiple batches. The original quality standards were promoted comprehensively ensuring the uniformity, stability and controllability of product quality. This study not only provided important theoretical and experimental basis for clinical application and guiding clinical practice, but also provided research ideas and modes for the secondary development of other major CMM.
