Four new oxypregnane-oligoglycosides, mucronatosides A (1), B (2), C (3), and D (4), together with one known stephanoside E (5) were isolated from the stems of Stephanotis mucronata (Blanco) Merr.. Their chemical structures were determined on the basis of chemical and extensive spectroscopic methods including one-dimensional and two-dimensional NMR.

A silica-supported arsine palladium(0) complex has been prepared from γ-chloropropyltriethoxysilane via im-mobilization on fumed silica, followed by reaction with potassium diphenylarsenide and palladium chloride, and then reduction with hydrazine hydrate. The complex has been characterized by X-ray photoelectron spectroscopy (XPS) and it is a highly active and stereoselective catalyst for arylation of butyl acrylate and acrylamide with aryl halides, affording a variety of trans-butyl cinnamates and trans-cinnamamides in high yields.

A newly synthesized reagent 2-amino-5-mercapto-[1, 3, 4]triazole (MATZ) has been usedto fabricate self-assembled monolayers (SAMs) on gold electrode for the first time. The SAMselectrode was characterized by electrochemical methods and scanning electronic microscopy (SEM),the SAMs electrode can be used to determinate dopamine (DA) and uric acid (UA) simultaneouslywith a detection limit of 8×10-7 mol/L for DA and 1×10-6 mol/L for UA respectively. The SAMscan also be used to detect the contents of DA and UA in synthetic urine sample with satisfactoryresults.
