RESUMO
A new flavonoid, 6-(5-acetyl-2-methoxyphenyl)-apigenin (1), together with nine known compounds (2-10), was isolated from Selaginella uncinata (Desv.) Spring. This is the first report of the spectroscopic data of compound 3. Compound 2 was first reported from this species. The structure of the new compound was elucidated on the basis of spectroscopic evidence, including 1D and 2D NMR as well as HR-EI-MS analysis.

A new selaginellin derivative, selaginellin M (1), together with one known compound, selaginellin E (2), was isolated from Selaginella pulvinata. The structure of the new compound was elucidated and named as (R,S)-4-((4'-hydroxy-4-((2-hydroxyethoxy)methyl))-3-((4-hydroxyphenyl)ethynyl)biphenyl-2-yl)(4-hydroxyphenyl)methylene)cyclohexa-2,5-dienone on the basis of the spectroscopic data including UV, IR, 1D, and 2D NMR as well as HR-ESI-MS analysis.
