摘要 目的:研究云南当地药材灯台树的化学成分。方法:运用硅胶柱色谱分离、光谱技术(核磁共振,红外,紫外和质谱)鉴定结构。结果:从灯台树叶中分离到4个鸭脚树叶碱类型的单萜吲哚生物碱:5β-methoxyaspidophylline(1),鸭脚树叶碱(2),鸭脚树叶醛(3),5-methoxystrictamine(4)。结论:1是一个新化合物。 AIM : To investigate the chemical constituents of Yunnan local medicinal plants Alstonia scholaris. METHODS: Silica gel column chromatography was used to isolate the constituents, and spectroscopic techniques ( NMR, IR, UV and MS) were used for structural elucidation. RESULTS : Four picrinine-type monoterpenoid indole alkaloids, 5^-methoxyaspidophyUine (1) , picrinine ( 2 ), picralinal (3) and 5-methoxystrictamine (4) were obtained from the leaves of Alstonia scholaris. CONCLUSION: Compound 1 is a new monoterpenoid indole alkaloid.
