Tripterygium wilfordii is a traditional Chinese medicinal herb with a long history of therapeutic use but remains controversial in modern medicine because of its potent toxicity. Among its diverse chemical constituents, the diterpenoid triptolide and the triterpenoid celastrol have emerged as prominent compounds due to their remarkable pharmacological activities, including antitumor, immunosuppressive, anti-obesity, and neuroprotective effects. However, their clinical translation is limited by toxicity concerns and restricted natural availability. This review summarizes the medicinal history and chemical constituents of T. wilfordii, with particular emphasis on the pharmacological mechanisms, structural modification strategies, and recent advances in the biosynthesis of triptolide and celastrol. In addition, we discuss perspectives on toxicity mitigation and lead compound development, aiming to provide theoretical guidance and valuable references for modern drug development and the green manufacturing of T. wilfordii-derived resources.

Objective To optimize the formulation of the sunscreen used in military training.Methods The different formulations of sunscreen were prepared according to the orthogonal design,and then applied on 3M adhesive tape posted on the color dish with a certain amount;the absorbance in 280 nm-320 nm and 320 nm-400 nm of them were measured and the arithmetic mean (A) was concluded.By comparing A,the protective effect and the main factors affecting preventive bask were determined.The preventive bask test of the optimum formula was carried out in human trials using the method of multi point increasing ultraviolet irradiation.Results OMC,TinosorbTM M,rutin,pearl powder and baicalin all had significant effects in preventing UVA.OMC had a significant effect in preventing UVB.The formula 1 (containing the five materials mentioned above) had the best effects in preventing both UVA (SPF 18) and UVB (PA+).Conclusions The formula 1 has the best effects in preventing both UVA and UVB.
