  Two biflavonoids from Ouratea nigroviolacea

  摘要：

  The leaves of Ouratea nigroviolacea (Ochnaceae) afforded two billavonoids, ouratine A and B together with agathisflavone and stigmasterol. The biflavonoids were characterized as 4'-O-methylated apigeninyl-(I-6, II-8)-4'-O-methylatedapigenin and 4'-O-methylated apigeninyl-(I-6, II-8) apigenin by spectral and chemical transformation studies.
