Article Abstract
The MS and multi-MS spectra of gambogic acid and gambogenic acid in positive ion detection mode were analyzed by electrospray ion trap mass spectrometry (ESI-QITMS) and their cleavage patterns were summarized. Gamboge samples were separated by a Kromasil C18 column and analyzed by HPLC-PDA and MS. Sixteen xanthones could be separated and detected, A collision induced dissociation (CID) experiment was carried out. Molecular weight and UV spectra with of these compounds were obtained. Ten xanthone compounds in Gamboge were identified by online photodiode array detection-MS(n) and by comparing with data from literature. It is expected to develop a comprehensive quality control method for this kind of compounds in commonly used herbal preparation especially in structure analysis of trace substances.

Serine hydroxymethyltransferase (SHMT) plays a critical role in the 1C metabolism pathway. This pathway is involved in the synthesis of many amino and nucleic acids, and SHMT is considered a target for drugs through folate metabolism, especially for cancer and malaria. A detailed analysis of the interactions between SHMTs and drugs will greatly contribute to the development of new drugs.

In this study, a quantum chemical exploration was conducted to assess the antioxidant activity of xanthones isolated from marine sources, focusing on thermodynamics and kinetics within simulated physiological environments. DFT analysis revealed that xanthones such as 1,4,7-trihydroxy-6-methylxanthone (), 1,4,5-trihydroxy-2-methylxanthone (), arthone C (), 2,3,4,6,8-pentahydroxy-1-methylxanthone (), sterigmatocystin (), oxisterigmatocystin C (), and oxisterigmatocystin D () favor the SPLET pathway in water and the FHT pathway in lipid environments. The kinetic study of these xanthones reacting with the hydroperoxyl radical (HOO•) was conducted using the formal hydrogen atom transfer (FHT) mechanism and the single electron transfer (SET) mechanism.

This study explores the use of green solvent systems by investigating the solubility and thermodynamic properties of xanthone (1) in triglyceride-based tricaprin (2) and tricaprylin (3) mixtures, aiming to replace traditional organic solvents. The solubility profile exhibited a concave trend, and the highest solubility was observed at a solute-free fraction (x) of 0.36.
