Objective To search for the method used in enriching caffeates in Cirsium setosum by macroporous adsorption resin, 23 types of macroporous adsorption resin were optimized, which could provide the industrial production of caffeates with the theory basis. Methods The adsorption and elution ratios, product purity and yield, as total indices, were comprehensively evaluatued by 23 types of macroporous adsorption resin in enriching the extracts in C. setosum. Results The product purity and yield of caffeates by the HPD-100 type macroporous adsorption resin were the highest and up to 52.2% and 87.6%. Conclusion The HPD-100 type macroporous adsorption resin shows better comprehensive adsorption property. It is available for the enrichment of caffeates in C. setosum.

The article reviewed the research progress of ligustilide in recent years and elaborated its pharmacological functions and mechanisms in detail,especially in ischemic brain injury.Its mechanism includes reducing cerebral infarct volumes and improving neurobehavioral deficits,anti-oxidant and anti-apoptosis,antithrombotic activity,calcium channel blockers function,and effect on erythropoietin.Other pharmacological effects of ligustilide including inhibiting vascular smooth muscle cell proliferation,anti-inflammatory and analgesic effects,effects on LPS-induced endotoxic shock,inhibiting constriction effect,suppression of the central nervous system,and ameliorating the memory impairment induced by scopolamine and so on,are also introduced.Ligustilide has potential pharmacological value,which provides a reference for its further research and development.

Precision medicine pointed out the future direction for medicine,providing new opportunities for the development of TCM,putting forward higher requirements and encountering severe challenges of the quality research of TCM.In view of the core connotation of precision medicine and the characteristics of TCM,we presented the precision connotation of quality based on the basic attributes,the clinical application and function characteristics of TCM in accordance with the thinking mode and method of the transformation research.In this article,we indicated the research approach for the scientific evaluation and effective control of quality based on the precise cognition of TCM.
