title: [Biologically active substances isolated from Hypericum attenuatum Choisy].
abstract: Four dianthrones, two oxymethylanthraquinones, two reductive forms of anthraquinones and five flavonoids have been isolated from the plant source Hypericum attenuatum Choisy (Guttiferae) firstly investigated for these substances contents. Dianthrones pseudohypericin, protohypericin, protopseudohypericin, oxymethylanthraquinones frangulaemodin, frangulin, reductive anthraquinones emodin anthrone, emodin anthranol, and flavonoids quercetin, quercitrin, isoquercitrin, rutin have been identified for the first time.
