목적:연구운남당지약재등태수적화학성분.방법:운용규효주색보분리、광보기술(핵자공진,홍외,자외화질보)감정결구.결과:종등태수협중분리도4개압각수협감류형적단첩신타생물감:5β-methoxyaspidophylline (1), 압각수협감(2),압각수협철(3),5-methoxystrictamine (4).결론:1시일개신화합물.
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, 5β-methoxyaspidophylline (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.
