title: Two new flavonoids from Selaginella uncinata.
abstract: Two new flavonoids, uncinataflavones A (1) and B (2), along with one known compound 6-(5-carboxyl-2-methoxyphenyl)-apigenin (3), were isolated from Selaginella uncinata (Desv.) Spring. All these compounds belong to apigenin derivatives with aryl substituents at C-6 position. The structures of new compounds were elucidated on the basis of comprehensive spectroscopic analyses (UV, IR, 1D, and 2D NMR as well as HR-ESI-MS).
