Multifunctional liposomes incorporating β-sitosterol were developed for delivery of gentisic acid (GA). The interactions of both compounds with phospholipid bilayer were interpreted viaeffects of different β-sitosterol content (0, 20 and 50 mol %) and different gentisic acid to lipid ratio (n/n from 10 to 1) on membrane fluidity and thermotropic properties. Multilamellar vesicles of phosphatidylcholines (with size range between 1350 and 1900 nm) effectively encapsulated GA (54%) when n/n was higher than 0.01. Suppression of lipid peroxidation was directly related to concentration of GA. The resistance to diffusion of gentisic acid from liposomes increased for ˜50% in samples incorporating 50 mol % β-sitosterol compared to sterol-free liposomes. Finally, simulated in vitro gastrointestinal conditions showed that the release was mainly affected by low pH of simulated gastric fluid and the presence of cholates in simulated intestinal fluid, rather than by enzymes activity.

Based on the focal adhesion kinase(FAK)/steroid receptor coactivator(Src)/extracellular regulated protein kinase(ERK) pathway, this study explored the effects of Xihuang Pills on angiogenesis, invasion, and metastasis in prostate cancer. Liquid chromatography-tandem mass spectrometry(LC-MS/MS) was used to analyze and identify the active ingredients of Xihuang Pills. Bioinformatics techniques, including R language and Perl programs, were employed to analyze the interactions between prostate cancer-related targets and the potential targets of Xihuang Pills.

Objective: To detect phenolic acid compounds in various fruits and explore the differences in phenolic acids among different types of fruits.
Methods: The collected 75 types of fruits were classified into 6 categories: citrus、melon、drupe、berry、tropical fruit and pome fruits. The phenolic acid compounds were detected by high performance liquid chromatography-mass spectrometry.

Ethnopharmacological Relevance: Huangkui capsule (HKC), a patent traditional Chinese medicine, has shown significant efficacy in managing chronic kidney disease (CKD), particularly diabetic nephropathy (DN). Previous studies have shown that HKC can alleviate kidney damage in DN. However, the exact mechanisms through which it exerts its effects remain unclear.

One percent of persons over 65 years of age suffer from Parkinson's disease, a neurological ailment marked by dopaminergic neurons in the nigrostriatal pathway gradually dying and being depleted in the striatum. Parkin and PINK1 gene mutations, which are essential for mitophagy and impair mitochondrial function, are the cause of it. Parkinson's disease is linked to a number of motor and impairment disorders, including bradykinesia, rigid muscles, tremor at rest, and imbalance.

Asthma, a lung disorder that causes impaired respiratory function, is characterized by an apparent infiltration of inflammatory cells. Gentisic acid (GA), a phenolic acid common in food ingredients, has antioxidant, antibacterial, and anti-inflammatory properties. Its potential application in mitigating asthma, however, remains unexplored.
