ABSTRACT
Traditional Chinese medicine (TCM) as the oldest and the most complete theoretical system with the largest number of users and most abundant varieties of medicinal materials in human history, has been playing a huge role in human development and progress. Based on the author's decades of experience in herbal medicine research, the following aspects including current situation and prospects of research on compound Chinese materia medica (CMM), concept of generalized CMM and diversity, personalized diagno-treatment of TCM, and quality standardization of CMM, prevention-prior to treatment and health-maintaining sciences, key factors affecting the efficacy of CMM, and to bring CMM to gentleman level are discussed. It is expected to promote the development and modernization of TCM.
ABSTRACT
With the development of Tibetan medicine industry, the demands for Tibetan medicine were rising sharply. In addition, with the eco-environment vulnerability of Qinghai-Tibet Plateau region and the phenomenon of synonymies and homonymies in Tibetan medicine, there were a lack of resources and varieties in the clinical application of Tibetan medicine. At present, the shortage of Tibetan medicine and the inadequacy of its quality standard have become the two major problems that seriously restricted the sustainable development of Tibetan medicine industry. Therefore, it is important to develop the resources investigation and quality evaluation for Tibetan medicine, which were contribute to its resources protection and sustainable utilization. In this paper, current status of resources investigation, quality standardization, artificial breeding and germplasm resources of Tibetan medicine were presented by the integrated application of the new technologies, such as DNA barcoding and 1H-NMR, which provided a reference information for resources protection, sustainable utilization, variety identification and quality standardization of Tibetan medicine resources in Qinghai-Tibet Plateau.
ABSTRACT
Biological evaluation is a critical approach by which the quality standardization of traditional Chinese medicines can be linked to the clinical efficacy and safety, which has become an important aspect in the develop-ment of quality standardization of Chinese medicines. In this article, the necessity and feasibility of the biological e-valuation research were analyzed. Further, the main progress achieved as well as the major problems about the re-search and applications of the biological evaluation of traditional Chinese medicines were discussed, to bring forward a point for consideration or discussion.
ABSTRACT
Quality standardization of complementary medicine is fundamental for industry and practice as it underpins the quality,safety and efficacy of Chinese herbal medicines.Current herbal standardizations are often based on the quantitative analysis of a single compound,which may not reflect the total characteristic,bioactive and toxic nature of the herbs or products.Therefore,there is a need to establish an internationally recognized methodology for quality standardization of Chinese herbal medicines.The analytical methods reviewed in this article are pharmacognosy,TLC,HPLC,LCMS,CE and chemo-metrics.This article also covers the developments and applications of these methods in quality standardization.Recent advances show that a combination of these methods creates an overall chemical profile of each herb.This iS supported by results reviewed in this article and obtained in our laboratory tests on medicinal herbs including Hypericum perforatum,Morinda officinalis and Centella asiatica.Significant variations in active components have been observed between herbal samples and products.It is proposed that the identification of active components,pharmacological activities and eventual clinical applications are required for a comprehensive quality standardization system.Our findings indicate that the combination of various chromatographic and chemometric methods will advance the methodology of quality standardization and enhance the overall confidence in herbal medicine for the health practitioner and the public.
