Review of chemical constituents, pharmacological effects and clinical applications of Jiaotai Pills and predictive analysis of its quality marker(Q-marker) / 中国中药杂志

Jiaotai Pills is a traditional medical prescription to treat the incompatibility of heart and kidney. It has the distinctive functions of heart and kidney communication, sedation and hypnosis, anti-anxiety and depression, as well as the improvement of insulin resistance. However, this pill is broadly used to cure insomnia, anxiety, depression, and diabetes in the contemporary clinical trials. Based on the article, it illustrates the research progress of the chemical ingredients, pharmacological actions, and clinical applications of Jiaotai Pills. With respect to the "five principles" of Q-marker in Chinese medicine, the Q-marker of Jiaotai Pills is comprehensively predicted and analyzed, noting that berberine, epiberberine, coptisine chloride, palmatine chloride, berberine chloride, berberrubine chloride, ferulic acid, cinnamic acid, cinnamaldehyde, proanthocyanidin B2 can be treated as the Q-marker of Jiaotai Pills. In addition, these components of Q-marker have been selected as indicators to provide a significant reference for the quality control and surveillance research of Jiaotai Pills.

Optimization of Scutellaria baicalensis extraction process by orthogonal experiment combined with pharmacodynamic index / 中国中药杂志

To optimize the Scutellaria baicalensis extraction process, the filter paper method and the bacteriostatic ratio method were adopted to determine the in vitro bacteriostatic efficacy of water extracts and 60% alcohol extracts from S. baicalensis. The quantitative analysis of multi-components by single-marker (QAMS) was used to determined the contents of four active components, baicalin, wogonoside, baicalein and wogonin. In addition, with the bacteriostatic ratio and the overall desirability of the contents of four active components as indexes, the orthogonal experiment was adopted to detect the effect of water addition, extraction frequency and extraction time. The optimal extraction process was to add 12 times of water for the first time, 10 times of water for the second time, extract for 2 time, 2 h for each time. This optimization process is stable and feasible, with a higher bacteriostatic ratio in extracts.
