Dilatatin, the xanthone-C-glycoside previously isolated from the filmy fern Hymenophyllum dilatatum, is identified as 2-C-β-D-allopyranosyl-1,3,6,7-tetrahydroxyxanthone.The glycosyl moiety is demonstrated to be allopyranose by 13C NMR spectroscopy using synthetic β-D-allopyranosyl-2,4,6-trimethoxybenzene as a model. - Key Word Index: Hymenophyllum dilatatum; Hymenophyllaceae; Filicales; dilatatin; xanthone C-glycoside; allose; 2-C-β-D-allpyranosyl-1,3,6,7-tetrahydroxyxanthone; dilatatin; synthesis.
