Abstract: One new biflavonoid was isolated from the 60 % ethanol extract of the dried whole herbs of Selaginella uncinata (Desv.) Spring. On the basis of physio-chemical properties and spectral (mainly 1 D and 2 D NMR) data, the structure of the new biflavonoid was established as 2′′, 3′′-dihydrorobustaflavone 4′-methyl ether (4). Along with the new biflavonoid, three known compounds robustaflavone (1), robustaflavone 4′-methyl ether (2) and tetrahydrorobustaflavone (3), were isolated. Compounds 2 and 3 were isolated from Selaginella uncinata (Desv.) Spring for the first time.

Key words: Selaginella uncinata (Desv.) Spring, biflavonoids, 2′′, 3′′-dihydrorobustaflavone 4′-methyl ether
