Article Synopsis
- - Chemical compounds were extracted and identified from the stems and leaves of *Cratoxylum cochinchinense*, using various chromatography techniques, leading to the isolation of 21 different compounds.
- - Out of these, one compound was a new xanthone, while several others had not been previously identified in the *Cratoxylum* plant; some were newly discovered in *C. cochinchinense*.
- - The isolated compounds were assessed for their anti-rheumatoid arthritis effects, with xanthones 1-15 showing significant inhibition of synoviocyte proliferation, indicating potential therapeutic benefits.

The chemical constituents from the fruits of Morinda citrifolia were systematically explored by chromatographic fractionation methods including silica gel, octadecylsilyl(ODS) gel, Sephadex LH-20 gel, and preparative high performance liquid chromatography(pre-HPLC). The chemical structures of all isolated compounds were identified on the basis of their physicochemical properties, spectroscopic analyses, as well as the comparisons of their physicochemical and spectroscopic data with the reported data in literature. As a result, 22 isolated compounds from the 90% ethanol extract of the fruits of M.

Semiconductor photocatalysis is an advanced oxidation process driven by solar energy which has widespread applications in the treatment of organic pollutants in liquid and gas phases. In this work, titanium dioxide nanoparticles modified with yttrium ions (Y) were prepared by a ball milling method. The effects of Y mole fraction, ball-to-powder weight ratio, milling time and milling rate on the photocatalytic activities were evaluated by the degradation of methylene blue (MB) under UV light.
