摘 要:Chemical examination of an unidentified sponge associated marine fungus Penicillium terrestre resulted in the isolation of eight compounds. Their structures are identified as cyclo (glycyl-D-proline) (1), cyclo (L-prolyl-L-alanine) (2), cyclo (L-prolyl- D-alanine) (3), cyclo (L-leucyl-trans-4-hydroxy-L-proline) (4), cyclo (L-leucyl-cis-4-hydroxy-D-proline) (5), cyclo (L-trans-(4- hydroxyprolinyl)-L-phenylalanine) (6), hexylitaconic acid (7), and hexylitaconic methylate (8), based on spectroscopic analysis (1D, 2D NMR). Compounds 7, 8 were obtained from the genus Penicillium for the first time, while compounds 1-6 were isolated from the fungus Penicillium terrestre for the first time.对分离自南海海绵的真菌Penicillium terrestre中的化学成分进行研究。采用多种色谱手段进行分离纯化,得到单体化合物,通过理化性质及波谱方法(1D,2D NMR)确定化合物结构。分离得到的8个化合物分别为cyclo(glycyl-D-proline)(1),cyclo(L-prolyl-L-alanine)(2),cyclo(L-prolyl-D-alanine)(3),cyclo(L-leucyl-trans-4-hydroxy-L-proline)(4),cyclo(L-leucyl-cis-4-hydroxy-D-proline)(5),cyclo(L-trans-(4-hydroxyprolinyl)-L-phenylalanine)(6),hexylitaconic acid(7),hexylitaconicmethylate(8)。化合物7,8为首次从该属中分得,其余化合物为首次从该种中分得。
