Dryopteris filix-mas (L.) Schott, Polypodiaceae, Flavan, Dihydrocoumarin, Lactone From acetone extracts of fresh aerial parts of Dryopteris filix-mas (L.) Schott a flavan-3-ol was isolated. Its structure was elucidated as 5-(3,4-dihydroxyphenyl)-3,3a,4,5-tetrahydro-4,8-dihydro-xy-2H-pyrano[4,3,2-ife]-l-benzopyran-2-one by means of spectroscopic methods including l3C-NMR.Keywords
