The isolation of skimmianine and three new acridone alkaloids from the root bark of Glycosmis pentaphylla (Retz.) Correa is reported. Based on the spectral evidence and chemical correlations, these are shown to be hitherto naturally unknown noracronycine (IIb), des-N-methyl-acrocynine (IXa) and des-N-methylnoracronycine (IXb). Evidence is also presented to show that of the two possible structures,
据报道,从五味甘蓝糖(Glycosmis pentaphylla(Retz。)Correa)的根皮中分离出了skimmianine和三种新的a啶酮生物碱。基于光谱证据和化学相关性,显示它们是迄今天然未知的去甲鸟新碱(IIb),去-N-甲基-鸟嘌呤碱(IXa)和去-N-甲基去甲鸟碱(IXb)。还提供证据表明,在两种可能的结构中,用于丙烯醛的1-甲氧基-2',2',10-三甲基吡喃并(5',6'-2,3或3,4)cri啶酮(Ia或IIa),角结构IIa是正确的。
