    ABSTRACT: A new nickel(II) saccharinate (sac) complex containing N,N′-bis(2-hydroxyethyl)ethylenediamine (bishydeten), [Ni(bishydeten)2](sac)2, has been synthesized and characterized by elemental analysis, FTIR and single crystal X-ray diffraction. The title complex consists of a [Ni(bishydeten)2]2+ cation and two sac anions. In the complex cation, the nickel(II) ion is coordinated by two neutral bishydeten ligands, leading to a distorted octahedral NiN4O2 coordination, while both sac anions remain outside the coordination sphere. In the crystal, the complex cations and sac anions are connected by an extensive network of N–H∙∙∙N, N–H∙∙∙O, O–H∙∙∙O and C–H∙∙∙O hydrogen bonds into a three-dimensional supramolecular lattice.

    ABSTRACT: A simple, accurate and precise method based on the fluorescence properties of the aluminum(III)–quercetin complex, for the determination of quercetin, has been developed and validated. The complex has strong emission at pH 3.30, em = 480 nm, with ex = 420 nm. The linearity range of quercetin deter-mination was 1.5–60.5 ng ml–1 with LOD 0.09 ng ml–1 and LOQ 0.27 ng ml–1. Recovery values in the range of 99.9–100.2% indicate a good accuracy of the method. The established method was applied for the determination of quercetin in capsules, with a recovery value of 98.3%, standard deviation of 0.22% and coefficient of variation of 0.09%. The reliability of the method was checked by the newly developed RP-HPLC/UV method for cap-sules with the direct determination of quercetin after separation. The good agreement between the two methods indicates the applicability of the proposed spectrofluorimetric method for quercetin determina-tion in pharmaceutical dosage forms, with high reproducibility, and enables the direct and simple deter-mination without its prior extraction from samples. The proposed spectrofluorimetric method has much better sensitivity and LOD and LOQ values that are about 1000 times lower than data reported in the literature.

    ABSTRACT: Chitosan oligomers (average Dp~4) are known for their antifungal activity and wood decay resistance. These oligomers are susceptible to moisture, and promote yeast growth upon air exposure after a sufficient length of time. Chitosan oligomers of three different states viz. completely dried, freshly prepared and highly viscous form, were prepared to compare their in-vitro antifungal activities against three brown-rot fungi, two sapstain and one mould fungus using agar nutrient medium. Additionally, a mixture of chitosan oligomers and boric acid was used for wood treatment. The nutrient medium bioassay results show that all states of chitosan oligomers inhibited the growth of tested basidiomycetes fungi, but not sapstain and mould fungi. Subsequently, wood decay results confirm antifungal activity of chitosan oligomers plus boron against basidiomycetes, but highlighted their leachability upon water exposure.
