Constituintes químicos dos frutos de Iryanthera paraensis Huber / Chemical constituints of Iryanthera paraensis HuberMagri, Fátima Maria Motter 17 February 1995 (has links)
Os frutos de Iryanthera paraensis Huber foram separados em suas partes constituintes e de seu pericarpo foi obtido o extrato clorofórmico que, por cromatografia e purificação em CLAE, forneceu cinco substâncias inéditas (uma neolignana e quatro γ-butanolidos): Eu-IP: reI (7S,8R)-4-hidroxi-3,5\'-dimetoxi-Δ1,3,5,1\',3\',5\',7- 7.O.3\',8.O.4\'-neolignana. A-1: (2S,3S,4S)-2-(9\'-fenil-n-nonil)-3-hidroxi-4-metilbutanolido. A-2: (2S,3R,4S)-2-(9\'-fenil-n-nonil)-3-hidroxi-4-metilbutanolido. B-1: (2S,3S,4S)-2-(11\'-fenil-n-undecil)-3-hidroxi-4-metilbutanolido. B-2: (2S,3R,4S)-2-(11\'-fenil-n-undecil)-3-hidroxi-4-metilbutanolido. A determinação das estruturas destas substâncias foi baseada principalmente em técnicas espectrométricas (EM, IV, RMN de 1H e de 13C). / The pericarps were removed from fruits of Iryanthera paraensis Huber, dried, ground and percolated with chloroform. The chloroform extract submitted to chromatographic techniques followed by HPLC purification, yielded a new neolignan and four new butanolides: Eu-IP: reI (7S,SR)-4-hydroxy-3,5\'-dimethoxy-Δ1,3,5,1\',3\',5\',7-7.O.3\',S.O.4\'-neolignan. A-1: (2S,3S,4S)-2-(9\'-phenyl-n-nonyl)-3-hidroxy-4-methylbutanolide. A-2: (2S,3R,4S)-2-(9\'-phenyl-n-nonyl)-3-hidroxy-4-methylbutanolide. B-1: (2S,3S,4S)-2-(11\'-phenyl-n-undecyl)-3-hidroxy-4-methyl-butanolide. B-2: (2S,3R,4S)-2-(11\'-phenyl-n-undecyl)-3-hidroxy-4- methyl-butanolide. The structural determination of these substances were based mainly on spectrometric methods (MS, IR, 1H and 13C NMR)
