摘要:

采用多种色谱分离方法从柳叶五层龙(Salacia cochinchinensis Lour)的茎叶中分离得到5个化合物. 通过一维(1D)及二维核磁共振波谱(2D NMR), 包括核磁共振氢谱(1H NMR)、 核磁共振碳谱(13C NMR)、 异核单量子相关(HSQC)、 异核多键相关(HMBC)、 氢氢相关(1H-1H COSY)和旋转坐标中的欧沃豪斯增强光谱(ROESY), 以及红外光谱(IR)和电喷雾电离高分辨质谱(ESI-HRMS)等方法, 鉴定其结构分别为Salaciacochinoside A(1), 5'-O-3,4,5-trimethoxybenzoyl-β-D-apiofuranoside(2), 5-methoxy-anticerol A(3), 21α,30-dihydroxy-D∶A-friedooleanan-3-one(4)和21α,26-dihydroxyfriedelan-3-one(5). 化合物1~3为新化合物. α-葡萄糖苷酶抑制活性测试结果显示, 化合物1和3对α-葡萄糖苷酶具有显著的抑制作用, 其IC50值分别为0.32和0.59 μmol/L; 化合物2, 4和5未表现出α-葡萄糖苷酶抑制活性.

Abstract:

Five compounds were isolated from the stems and leaves of Salacia cochinchinensis Lour. By comprehensive spectroscopic analyses including mass spectroscopy(MS), infrared radiation(IR), 1D and 2D nuclear magnetic resonance(NMR) [heteronuclear single quantum coherence(HSQC), heteronuclear multiple bond correlation(HMBC), 1H-1H chemical-shift correlation spectroscopy(1H-1H COSY) and rotating frame overhauser effect spectroscopy(ROESY)], their structures were elucidated as Salaciacochinoside A(1), 5'-O-3,4,5-trimethoxybenzoyl-β-D-apiofuranoside(2), 5-methoxy-anticerol A(3), 21α,30-dihydroxy-D∶A-friedooleanan-3-one(4) and 21α,26-dihydroxyfriedelan-3-one(5), respectively. Compounds 1—3 were new compounds. All the compounds were assayed for the anti-diabetic activities. Compounds 1 and 3 exhibited remarkable bioactivity, inhibiting α-glucosidase with IC50 values of 0.32 and 0.59 μmol/L, respectively. Compounds 2, 4 and 5 showed none anti-diabetic activity in current experiment.
