The structures 4′,5-dihydroxy-2′,3,7,8-tetramethoxyflavone and 5-hydroxy-2′,3,4′,7,8-penta-methoxyflavone have been attributed to two new compounds isolated from a farinose exudate of Notholaenaaffinis; this result is derived from uv, ms, and nmr spectra of the natural products and their derivatives.
