Article Abstract
Tongxie Yaofang (TXYF) is a famous formula that has been used for treating gastrointestinal diseases in traditional Chinese medicine(TCM). Saposhnikoviae Radix is considered as a meridian guiding drug in TXYF and could enhance the effectiveness of prescription. However, the scientific evidence for this effect is still not clear. To reveal the interactions of Saposhnikoviae Radix with other herbs, we conducted this study on the pharmacokinetic profile and tissue distribution of active ingredients of TXYF in rats. The concentrations of four components in blood and tissues were determined by UPLC-MS/MS after oral administration with TXYF. The detection was carried out by electrospray ionization mass spectrometry in the multiple reaction monitoring (MRM) mode. The positive and negative ion switching technique was performed in the same analysis. The results revealed that Saposhnikoviae Radix could enhance Cmax, AUC0-t, and AUC0-∞ of paeoniflorin and hesperidin, and increase the distribution of atractylenolide-I, paeoniflorin and hesperidin in liver, spleen, brain and small intestine. Saposhnikoviae Radix increased the ratio of brain to blood concentrations of atractylenolide-I, paeoniflorin and hesperidin. Meanwhile, it reduced the ratio of lung to blood concentrations of atractylenolide-I and paeoniflorin. Saposhnikoviae Radix, and may enhance the effectiveness of prescriptions by promoting distribution of other herbs in brain.

Thunberg is a perennial herbaceous plant of the genus that belongs to the Apiaceae family and is effective in improving inflammation, gout, and dizziness. However, the skin pruritus improvement effect and mechanism of action of Thunberg root extract (PJRE) have not yet been reported. We investigated the effects of PJRE on the regulation of pruritus and inflammatory responses in compound 48/80 (C48/80)-treated mice, phorbol 12-myristate 13-acetate (PMA)/A23187-induced human skin mast cells, and LPS-stimulated mouse macrophages.

The study investigated the intrinsic changes in material basis of Angelicae Sinensis Radix during wine processing by headspace-gas chromatography-ion mobility spectrometry(HS-GC-IMS), headspace-solid phase microextraction-gas chromatography-mass spectrometry(HS-SPME-GC-MS), and ultra-high performance liquid chromatography-quadrupole-orbitrap mass spectrometry(UPLC-Q-Orbitrap-MS) combined with chemometrics. HS-GC-IMS fingerprints of Angelicae Sinensis Radix before and after wine processing were established to analyze the variation trends of volatile components and characterize volatile small-molecule substances before and after processing. Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were employed for differentiation and difference analysis.

Although Peucedanum japonicum Thunb (PJT) has been used in traditional medicine, PJT root is considered to be agricultural waste, and its benefits have not been explored to date. This study examined the effect of PJT root extract in C57BL/6J mice fed a high-fat diet (HFD) for 10 weeks and determined the underlying molecular mechanisms based on gene expression analyses. PJT supplementation (1% w/w) decreased body weight, white adipose tissue (WAT) mass, and hepatic triglyceride levels and downregulated inflammatory gene expression in the WAT and liver of HFD-fed mice.

Species of the genus are known for their traditional medicinal applications against diverse illnesses. Our previous study was the first to suggest the cholinesterase inhibitory activity of L. However, the neuroprotective efficacy of therapeutic molecules is often limited by their ability to cross the blood-brain barrier (BBB) and reach the brain.

Aging is characterized by a progressive decline in physiological functions and an increased susceptibility to age-related diseases, yet effective interventions remain limited. Recent advancements in understanding the molecular mechanisms of aging have highlighted pathways such as insulin-like signaling, mTOR, and sirtuins. Meanwhile, traditional medicinal herbs are increasingly recognized for their potential to modulate these pathways.
