Biflavonoids in the julianiaceae

Phytochemistry, 1988
Abstract Amentoflavone and agathisflavone are reported in the leaves of species belonging in both genera of the Julianiaceae. This strongly supports a close affinity with the Anacardiaceae, and in particular with the tribe Rhoeae.

Electrochemical synthesis of biflavonoids

Chemistry of Natural Compounds, 2013
Biologically active biflavonoids have consistently attracted the attention of researchers [1]. However, only a few of these compounds have a broad spectrum of biological activity. This has prompted scientists to prepare their semi-synthetic and synthetic analogs [2]. Thus, several approaches including metal-catalyzed cross coupling, oxidative coupling,
