Two novel natural products, lanneaquinol (1) and 2'(R)-hydroxylanneaquinol (2), were isolated from the organic extract of the plant Lannea welwitschii (Hiern) Engl. Their structures were solved by spectroanalytical methods and confirmed by comparison to synthetic models. The absolute configuration of 2 was determined by the modified Mosher method. Both compounds exhibited modest cytotoxicity against
从植物Lannea welwitschii(Hiern)Engl的有机提取物中分离出了两种新颖的天然产物羊毛脂(1)和2'(R)-羟基羊毛脂(2)。通过光谱分析方法解析了它们的结构,并通过与合成模型进行比较来证实了它们的结构。2的绝对构型通过改进的Mosher方法确定。两种化合物均对60种人类肿瘤细胞系的NCI组显示出适度的细胞毒性。还阐明了两个异构的4,5-二羟基-5-烷基-2-环己烯酮(7和8)的结构,它们似乎是1和2的生物遗传前体。
