METHOD: The compounds were isolated and purified by silica gel and Sephadex LH20 column chromatography repeatedly, and their structures were identified by spectral analysis. RESULT: Eight compounds were isolated from the bark and wood of Nauclea officinalis, and their structures were identified as β-sitosterol(1), sitosterone (2), 3-O-acetylerythrodiol (3), vanillin (4), oleanlic acid(5), veratric acid(6), 3,4-dimethoxycinnamic acid(7), glycosmisic acid(8). CONCLUSION: Compounds 2~8 were isolated from this plant for the first time.展开更多
从胆木(Nauclea officinalis Pierre ex Pitard)树干中,分得两个新生物碱甙,分别命名为胆木碱庚(nauclecoside)和胆木碱辛(nauclecosidine)。根据它们的理化性质,光谱数据和化学反应,推断胆木碱庚的结构为Ⅰa,胆木碱辛为Ⅱa。并且还得...从胆木(Nauclea officinalis Pierre ex Pitard)树干中,分得两个新生物碱甙,分别命名为胆木碱庚(nauclecoside)和胆木碱辛(nauclecosidine)。根据它们的理化性质,光谱数据和化学反应,推断胆木碱庚的结构为Ⅰa,胆木碱辛为Ⅱa。并且还得到一已知碱胆木碱壬,鉴定为喜果甙(vincoside laetam,Ⅲ)。展开更多
目的对茜草科拉拉藤属植物蓬子菜(Galium verum L.)全草的乙醇提取物进行分离鉴定。方法经反复纯化制备化合物,并通过化合物的理化性质分析、波谱解析、对照品比较及与文献报道对比鉴定化合物的化学结构。结果分离得到7个化合物,...目的对茜草科拉拉藤属植物蓬子菜(Galium verum L.)全草的乙醇提取物进行分离鉴定。方法经反复纯化制备化合物,并通过化合物的理化性质分析、波谱解析、对照品比较及与文献报道对比鉴定化合物的化学结构。结果分离得到7个化合物,根据理化性质和波谱学解析分别鉴定为东莨菪素(1)、阿魏酸(2)、对羟基苯丙酸(3)、香豆酸三十二烷酯(4)、正三十二烷醇(5)、β-谷甾醇(6)和胡萝卜苷(7)。结论化合物1—5为从本属中首次分离得到。展开更多
