Studies on the Chemical Constituents of Woodwardia japonica

Abstract:

Five compounds have been firstly isolated from Woodwardia j aponica (L. f.) Sm. On the basis of spectral analysis, the structures of these compounds were identified as kaempferol 3-O-á-L-(4-O-acetyl)rhamnopyranos ide-7-O-á-L-rhamnopyranoside (I), kaempferol 3-O-á-L-rhamnopyranoside-7-O-á-L-rhamnopyranoside (II), woodwardinic acid (III), a-sitosterol (IV), daucosterol (V).
