Abstract
Six new alkaloids, viz., alstolactone, affinisine oxindole, lagumicine, N(4)-demethylalstonerine, N(4)-demethylalstonerinal, and 10-methoxycathafoline N(4)-oxide, in addition to 36 other known alkaloids, were obtained from the leaf extract of Alstonia angustifolia var. latifolia. The structures of the new alkaloids were determined using NMR and MS analysis.
摘要
除了36种其他已知生物碱外，从阔叶鸡骨常山的叶提取物中还获得了6种新生物碱，即鸡骨常山内酯、阿菲尼西宁吲哚酮、拉古米辛、N(4)-去甲基鸡骨常山碱、N(4)-去甲基鸡骨常山灵以及10-甲氧基咔他佛林N(4)-氧化物。通过核磁共振（NMR）和质谱（MS）分析确定了这些新生物碱的结构。
