对酒饼叶根的甲醇-二氯甲烷提取物的化学成分进行了研究。从上述提取物中分离得到1种新的萘醌类生物碱glycoquinone和1种新的吖啶酮类生物碱glycocitrine-Ⅲ。另外,还分离得到12个已知的化合物。运用光谱分析确定了2个新化合物的结构。这是首次从酒饼叶属植物中分得萘醌类衍生物。
The chemical composition of the methanol-dichloromethane extract of the wine cake root was studied. A novel naphthoquinone alkaloid glycoquinone and a novel acridinone alkaloid glycocitrine-III were isolated from the above extract. In addition, 12 known compounds were also isolated. Spectral analysis was used to determine the structure of the two new compounds. This is the first time that naphthoquinone derivatives have been obtained from the genus Dioscorea.
