| 摘 要： | Isatis indigotica Fort., a most popular Chinese traditional medicine, is usually used to clear heat and detoxicate. We report here the isolation of E-2-(3'-indole)cyanomethylene]-3-indolinone 1 (Scheme) from the butanol-soluble fraction of I. indigotica., and structural elucidation of this new alkaloid.Scheme The HMBC correlation of compound 1The 80% EtOH extract of I. indigotica was partioned with petroleum ether, chloroform, ethyl acetate and n-butanol, respectively. The n-BuOH fract…
