There was investigated the quantity and structure of bitter substances and xanthohumol in lupulinin grains, in a mixture of blossom dust and lupulin in man's racemes and in a leaf of hop. It was found, that the quantity and structure (composition) of bitter substances in a lupulin of selection varieties does not depend on its quantity  in hop cones, and that it is a varietal attribute. It was found, that lupulin glands also are present on anthers of man's racemes, also on a leaf but in much lesser quantity and less educed there. Lupulin from the man's racemes, received from different plants, essentially differs in quantity of alpha and beta- acids. In petal glands (Ferri lactases) on a leaf of hop plant bitter substances are presented only by beta-acids, basically lupulone and adlupulone.
