CHEMISCHE UND CHEMOTAXONOMISCHE UNTERSUCHUNGEN VON FILICES. XXVII. CHEMISCHE UNTERSUCHUNGEN DER INHALTSSTOFFE VON DENNSTAEDTIA WILFORDII (MOORE) CHRIST.
From the aerial parts of Dennstaedtia wilfordii (MOORE) CHRIST, three new pterosins (pterolacton A, B and dennstopterosin) and two new pterosides (pterolacton A 3-O-β-D-glucoside and pterolacton A 3-O-β-D-(4'-p-coumaroyl)-glucoside) have been isolated together with pterosin A, D and L.Their structures have been established from spectroscopies evidences and chemical reactions.Keywords - Dennstaedtia wilfordii; fern; chemotaxonomy; pterosins; pterosides; structures; spectroscopic methods; chemical reactions.
