[Serum metabolomics reveals effects of standard decoction and formula granules of Paeoniae Radix Rubra on rat model of heat toxin and blood stasis].

This study aims to compare the effects and mechanisms of the standard decoction and formula granules of Paeoniae Radix Rubra in regulating the metabolism in the rat model of heat toxin and blood stasis. SD rats were randomized into control, model, standard decoction, and formula granules groups. After 14 days of administration, the rats in the latter three groups were subjected to subcutaneous injection with carrageenan and intraperitoneal injection with bacterial lipopolysaccharide for the modeling of heat toxin and blood stasis.

[Prediction and analysis of Q-markers of Elephantopus scaber based on its UPLC fingerprint, content determination of components, and in vitro a nti-tumor activity].

This study aimed to provide scientific evidence for predicting quality markers(Q-markers) of Elephantopus scaber by establishing UPLC fingerprint of E. scaber from different geographical origins and determining the content of 13 major components, as well as conducting in vitro anti-cancer activity investigation of the main components. The chromatographic column used was Waters CORTECS UPLC C_(18)(2.
