Abstract

A new biflavanone, 7,4″’-di- O-methyltetrahydrohinokiflavone (1) together with two known biflavonoids, tetrahydrohinokiflavone (2) and amentoflavone (3) were isolated from the whole plant of Selaginella rupestris. The structures of these compounds were elucidated by 1D- and 2D-NMR spectroscopy, and by mass spectrometry.
