[In vitro "benefit-risk" evaluation and network regulation mechanism of Colquhounia Root Tablets and its key material basis].

Colquhounia Root Tablets, prepared from Tripterygium, is effective for rheumatoid arthritis, diabetic nephropathy, and membranous nephropathy. However, the adverse reactions, such as liver injury, nausea, and vomiting, limit its application. This study aims to evaluate the advantages and risk of Colquhounia Root Tablets and its key active components in the treatment of rheumatoid arthritis, diabetic nephropathy, and membranous nephropathy and explore the potential mechanism in treating different diseases based on in vitro efficacy and toxicity assessment and biomolecular network analysis.

[Study on Chemical Constituents of Lonicera similis].

Objective: To study the chemical constituents of flower buds of Lonicera similis.

Methods: The compounds were isolated and repeatedly purified by macroperous resin, silica gel column, gel column, preparation of TLC, and RP C18, chromatography. Their structures were elucidated by physicochemical properties, MS and NMR.
