目的研究橙色手指海绵(Axinella sp.)的化学成分。方法采用硅胶柱色谱、Sephadex LH-20和反相半制备HPLC等方法分离化合物,根据波谱数据确定其结构。结果从橙色手指海绵分离得到10个化合物,鉴定为:cyclo-(Val—Pro)(1)、cyclo-(Tyr—Pro)(2)、cyclo-(Phe-Pro)(3)、cyclo-(Leu—Pro)(4)、cyclo-(Lle—Pro)(5)、2'-deoxyinosine(6)、2'-deoxyadenosine(7)、spongothymidine(8)、spongouridine(9)、2'-deoxyuridine(10)。结论所有化合物为首次从橙色手指海绵中分离得到。
OBJECTIVE To study the chemical constituents of Axinella sp. from the South China Sea. METHODS The com- pounds were isolated and purified by silica gel, Sephadex LH -20, and semi-preparative reverse-phase HPLC (C18). Their structures were identified by their spectral data. RESULTS Ten compounds were isolated from Axinella sp. and their structures were identified as cyclo- (Val-Pro) ( 1 ), cyclo- ( Tyr-Pro ) ( 2 ), cyclo- ( Phe-Pro ) ( 3 ), cyclo- (Leu-Pro) ( 4 ), cyclo- ( Ile-Pro ) ( 5 ), 2'-deoxyinosine (6), 2'-deoxyadenosine(7), spongothymidine (8), spongouridine (9)and 2'-deoxyuridine (10). CONCLUSION All the com- pounds were isolated from Callyspongia sp. for the first time.
