P.A. Gadek,C.J. Quinn +1 more
TL;DR: Twenty species, including representatives of all 11 genera of the Callitroideae, were examined for biflavonoid content of the leafy twigs, finding five groups that do not correlate strongly with currently recognized tribal groupings.

Biflavones from the leaves of Araucaria excelsa
TL;DR: In this article, eight biflavones have been isolated from the leaf extracts of Araucaria excelsa for the first time, including 7,7″-di-O -methyl agathisflavone and 7,4′,7''tri-O''methylamentoflavone.

Biflavones of Dacrydium sensu lato
TL;DR: A survey of the biflavonyls in the leaves and branchlets of all three sections of the genus Dacrydium revealed a complex mixture of amentoflavone and its partial methyl ethers and hinokiflavone in most species.

The Chemistry of Biflavanoid Compounds
TL;DR: Fossilised remains of the Ginkgo biloba tree establish that it was in existence some 250 million years ago (during the Cretaceous or even the Jurassic period of the earth’s evolution) and played an important part in the development of chemistry.

Biflavones of some Cupressaceae plants
TL;DR: Two solvent systems have been found to be useful for the TLC study of biflavones in conifer extracts and have also been used for obtaining chromatographically pure b iflavones and their methyl ethers by preparative TLC and “dry column” chromatography.
