    Phenylpyrydilylamino-4-Antipyrilemethan as Analytic Reagents

    The properties of some arylarylamino-4-antipyrilemethanes such as solubility in water and acidic solutions, in some organic solvents, pKa in water, constants of distribu-tion in system chloroform-water have been studied. It was found out that phenylpyry-dilylamino-4-antipyrilemethan has analytical etractive properties and these properties are characteristic of another arylarylamino-4-antipyrilemethanes. 99,9 % Au3+ was etracted in chloroform with this compound. The study of the analytical properties has shown that compounds can be used as etraction and photometric analytical agents.

    Key words: phenylpyrydilylamino-4-antipyrilemethan solubility, basicity, solvent etraction, analytical reagent.

    Biological Peculiarities of Seeds in Some Species of Trollius L. and Paeonia L.

    The morphometric parameters of seeds from si species of Trollius L. and two types of Paeonia L. were studied. We studied the dependence of seed germination on their morphometric parameters for several species of peony flowers and globeflowers, which used to be considered as belonging to the same family Ranunculaceae earlier. The terms of seed germination were determined. Resting period types were described to reveal the dependence of seed germination terms on the germ size in Trollius. For Trollius ledebourii seeds the absence organic rest was recorded.

    Key words: seed germination, the germ, peony flower, globeflower.
