摘要: 采用多种色谱法从思茅山橙根部分的生物碱粗提物分离得到10个生物碱类化合物,利用波谱等方法对其结构进行鉴定,包括3种不同的生物碱骨架结构,分别为喹啉型生物碱:melodinhenine D(1)、melaxilline A(2)、11-methoxytabersonine(3)、meloscandonine(4)、melodinine T(5);白坚木型生物碱:venalstonidine(6)、vandrikidine(7);长春曼胺型生物碱:14,15-dehydrovincine(8)、14,15-dehydro-16-epi-vincamine(9)、△14-vincanol(10)。除化合物1,5和8外,其余化合物均首次从思茅山橙中分离得到。采用MTT法对分离所得的化合物进行体外抗人乳腺癌细胞MCF-7活性测试,结果显示化合物3表现出显著的细胞毒活性,其IC50值为23.4 μM。

Abstract: Ten alkaloids were isolated from the roots of Melodinus henryi by a combination of various chromatographic techniques,including column chromatography over silica gel,pH-zone-refining high-speed counter-current chromatography,and reversed-phase HPLC,etc.The structures of these alkaloids were determined on the basis of spectroscopic analysis including MS and NMR data,which were divided into three types,including quinine-type alkaloids:melodinhenine D(1),melaxilline A(2),11-methoxytabersonine(3),meloscandonine(4),melodinine T(5);aspidospermidine-type alkaloids:venalstonidine(6),vandrikidine(7);vincadine-type alkaloids:14,15-dehydrovincine(8),14,15-dehydro-16-epi-vincamine(9),△14-vincanol(10).All the compounds except 1,5 and 8 were isolated from Melodinus henryi for the first time.All the compounds were tested for their cytotoxicities against human breast cancer MCF-7 cells using the MTT method,and compound 3 exhibited significant cytotoxic effect with IC50  value of 23.4 μM.
