Abstract
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.
