From the methanol extract of dried powders of Hedyotis diffusa Willd. (Rubiaceae) plant growing in Tuyen Quang Province, three compounds were isolated and identified: B-sitosterol, daucosterol and ursolic acid. Their structures were confirmed by various spectral methods (IR, NMR, MS, 1H-NMR, 13C-NMR, etc.) and by comparison with those of references.

The procedure for determination of 238 U, 234 U, 232 Th, 230 Th and 228 Th nuclides by alpha spectroscopy was developed. Nuclides of uranium (U) and thorium (Th) were separated from the soil samples by chromatographic method. In the medium of 8 M nitric acid, U(VI) and Th(IV) were adsorbed on the Dowex 1 anion resin column. However, U(VI) was eluted from column by increasing the used volume of 8 M nitric acid. Th(IV) was eluted from the column with 50 ml HCl 9 M.

Hydrogels composed of polyvinyl pyrrolidone (PVP), polyethylenglycol (PEG) and kappacarrageenan (KC) were prepared by radiation crosslinking method. The equilibrium water absorption of hydrogel PVP/KC (A) and PVP/PEG/KC (B) were 45 and 85 g(H2O)/g dried gel, respectively. The n values of the equation Mt /M = ktn were determined to be of 0.6396 for hiđrogel A and 0.9984 for hydrogel B. The water transport mechanism follows the fickian diffusion for hydrogel A, while relaxation diffusion is dominated for hydrogel B. The water vaporization of hiđrogels was also investigated.

The comparative study of the content and structure characteristics of fucoidans from five Sargassum brown seaweed species in the south provinces of Vietnam was conducted. The yield of fucoidans was ca. 4% (w/w) based on dry seaweed. The percentage of sulfate and uronic acid content was determined by Scott method. Fucoidans were hydrolyzed with trifluoroacetic acid, acetylated and their L-fucose, D-xylose, D-rhamnose, D-mannose, D-glucose, and D-galactose contents were identified by gas chromatography.

Shikimic acid is an important product in the synthesis of the anti-influenza drug osseltamivir phosphate. LC-MS method was applied for the determination and quantification of shikimic acid from Vietnamese star anis (Illicium verum Hook.f.). Using the instrument system LC/MSD Agilent series 1110, separation was performed on a Zorbax SB-C18 RP (3.0x150 mm) column with water containing 0.1% formic acid and methanol as mobile phase. Analytes were detected both by DAD at 210 nm and by MS detectors.

In the Pt/
-Al2O3 catalysts, the distribution of uniform, small particle-size Pt metal on the carrier with high surface area of metal will result in high catalytic activities and will economize noble metals. The distribution of metal depends on the technology of preparation and postpreparation. The influences of the impregnating, drying, calcining and reducing on the distribution of metal have been studied using by physic methods, scan electronic microscope (SEM), transmission electronic microscope (TEM), and the hydrogen distribution has been measured by the method of hydrogen absorption.
