The complex of ZnL2Cl4 was synthesized by using zinc chloride hydrate and ligand 2-[(4-Methylpiperazin-1-yl)iminomethyl]phenol(L) under reflux conditions and anhydrous ethanol as solvent. The complex was characterized by elemental analysis, Infrared spectroscopy, solid fluorescence. Experimental results showed that the free ligand was thermally stable, and emitted intensive blue fluorescence at the peak wavelength of 493 nm. Compared with the fluorescent emission of free ligand, the complex of ZnL2Cl4 is blue-shifted to 448 nm in solid-state and exhibiting stronger blue fluorescence.

Aquasorb was prepared with naked oats straw and acrylic acid by graft copolymerization. Adopting orthogonal optimization design to determine the optimal levels of each factor of synthesis conditions, and carried on the various performance was detected. When prepared under the conditions that reaction temperature 70 °C, monomer concentration 12%, the dosage of initiator 1.50%, the amount of cross linking agent 0.15%, neutralization degree 80%, reaction time 3 h, monomer and straw mass ratio 10:1, rotate speed 600 r/min, the water absorbency of the aquasorb was 1012 g/g in deionized water, and 120 g/g in 0.9% NaCl solution. The aquasorb prepared under this condition expressed excellent salt resistance, water holding capacity, acid and alkali resistance.

Sinenxan H [2α,14β -diacetoxytaxa-4(20),11-diene-5α, 10β -diol, 1] was isolated from the heartwood of Taxus cuspidata, for the first time from natural sources. Compound 1 was found to be readily converted into 2α-acetoxytaxa-4(20),10,12(18),13-tetraen-5α-ol (2), the first example of a taxane with 10,11- and/or 13,14-double bond(s) and a conjugated triene system, in CDCl3.
