Título:  Effect of calcium carbonate fineness on plant growth and nutrient contents of wheat and bean plants in calcareous soils.

Conteúdo:  A pot experiment was carried out using soils mixed with CaCO3 in the size of > 0.02, 0.2, 2.0 and 5.0 mm. diameters of CaCO3 particles. Each size was representing 40% CaCO3 for all solis. Wheat and bean plants were planted and applied with constant doses of fertilizers. Fresh and oven dried weights were recorded and tissues were chemically analyzed for phosphorus and potassium. Results could be summarized in the followings. Wheat seeds were bad affected by fineness in germination while horse-bean plants were less affected due to its strongth of seedlings. For wheat plants treatments of 0.2 and 2.0 mm. CaCO3 sizes were the best followed by the coatser sizes (50 mm.) and the lowest were those of the finest size. Horse-bean plants were of stronger roots to grow easier in relatively coarser sizes of CaCo3. This was true also in regard of phosphorus and potassium concentrations in wheat and -bean plants and their total content per pot orf each soil treatment. Thus it could be recommended that plants of strong seeds must be initially cultivated in calcareous soils to face the first environmental conditions. Therefore, finer crop seeds could be cultivated when the soil surfaces take the stable shape of particles either by coagulating the fine ones or by filling the wide pore sapces of coarse CaCO3 particles by humus.

Título:  Solid cation exchange phase to remove interfering anthocyanins in the analysis of other bioactive phenols in red wine.

Conteúdo:  Bioactive phenols (BPs) are often targets in red wine analysis. However, other compounds interfere in the liquid chromatography methods used for this analysis. Here, purification procedures were tested to eliminate anthocyanin interference during the determination of 19 red-wine BPs. Liquid chromatography, coupled to a diode array detector (HPLC-DAD) and a mass spectrometer (UPLC-MS), was used to compare the direct injection of the samples with solid-phase extractions: reversed-phase (C18) and strong cation-exchange (SCX). The HPLC-DAD method revealed that, out of 13 BPs, only six are selectively analyzed with or without C18 treatment, whereas SCX enabled the detection of all BPs. The recovery with SCX was above 86.6% for eight BPs. Moreover, UPLC-MS demonstrated the potential of SCX sample preparation for the determination of 19 BPs. The developed procedure may be extended to the analysis of other red wine molecules or to other analytical methods where anthocyanins may interfere.
