ABSTRACT
Gegen Qinliantang is a representative prescription for dual releasing of exterior and interior and treating diarrhea with fever in the Treatise on Cold Damage and Miscellaneous Diseases (《伤寒杂病论》). This prescription consists of Puerariae Lobatae Radix, Scutellariae Radix, Coptidis Rhizoma, and Glycyrrhizae Radix et Rhizoma Praeparata cum Melle. The combination of the four herbal medicines has the ability to clear both the exterior and the interior, thereby halting diarrhea and clearing heat. According to the idea of treating different diseases with the same method, Gegen Qinliantang is used in clinical practice to treat type 2 diabetes mellitus (T2DM), which demonstrates positive outcomes. T2DM is a chronic metabolic disease characterized by elevated blood glucose levels. The etiology and pathogenesis of T2DM are complex, mainly related to heredity, lifestyle, environment, diet and other factors. Clinical observations and experimental studies have shown that Gegen Qinliantang and its effective ingredients have significant effects of preventing and treating T2DM. Clinically, Gegen Qinliantang is often applied with modification, or in combination with Western drugs, demonstrating better therapeutic effects than Western drugs alone. Clinical practice has confirmed that Gegen Qinliantang can effectively alleviate the clinical symptoms, reduce the occurrence of complications, and alleviate gastrointestinal adverse reactions in T2DM patients. Experimental studies have demonstrated that Gegen Qinliantang can ameliorate insulin resistance and boost pancreatic function by regulating the insulin and inflammation signaling pathways, alleviating oxidative stress, and modulating gut microbiota to treat T2DM. Nevertheless, more thorough studies remain to be carried out to decipher the mechanism of Gegen Qinliantang in ameliorating insulin resistance in T2DM. To provide theoretical and data references for the subsequent in-depth research on the mechanism of Gegen Qinliantang in treating T2DM and the prevention and treatment of this disease, this article systematically reviews the clinical and experimental research progress of Gegen Qinliantang in ameliorating insulin resistance in T2DM.
ABSTRACT
OBJECTIVE: To screen the quality control components of Chrysanthemum morifolium based multiple component metabolism, and study its network pharmacology effect. METHODS: The water extract of C. morifolium was prepared. A total of one rats were selected, water extract of C. morifolium was perfused in jejunum segment after abdominal anesthesia; plasma sample 1 was collected by double perfusion collection. Other 3 rats were given water extract of C. morifolium intragastrically, and plasma sample 2 was collected by abdominal aorta blood collection. UPLC-MS/MS was used to analyze water extract of C. morifolium and plasma sample component, and prototype blood-entry component in water extract of C. morifolium was identified after metabolism. TCMSP and Swiss Target Prediction database were used to screen the core target of prototype blood-entry component. DAVID database was used to enrich the related pathways of core target. The quality control components were screened according to topological parameters. Cytoscape software was used to analyze pharmacological effect of quality control components of C. morifolium. RESULTS: After UPLC-MS/MS analysis, 27 compounds were identified in water extract of C. morifolium, among which there were 12 prototype blood-entry components. After network pharmacology analysis, 7 quality control components were identified, i.e. cosmosiin, apigenin-7-O-glucuronide, luteolin, tilianin, apigenin, hesperetin, acacetin. It was possible to treat cancer, cardiovascular and cerebrovascular diseases, and neurological diseases by acting on metabolic pathway, cancer related pathway, signal transduction related pathway, adipocyte lipolysis regulatory pathway, etc. CONCLUSIONS: The study screen the possible quality control components of water extract of C. morifolium. The theoretical pharmacological effect of it can be clarified through network pharmacology, which can provide a new idea for the utilization of C. morifolium.
ABSTRACT
Objective To optimize the extraction technology of Compound purgative Moringa Oleifera by central composite design-response surface method. Methods The content of isoquercetin and astragalin, the yield of dry extract and overall desirability (OD) were used as the evaluation indexes; the factors such as water addition, extraction times and time for extraction were employed to optimize extraction technology of central composite design-response surface method. Results Optimal extraction technology was as follows: 3 times extracted with 10-fold the amount of water for 1 h each time. Conclusions Central composite design-response surface method was suitable for optimizing extraction technology of compound purgative Moringa Oleifera.
