Three new flavanol glycosides, 1 – 3 , and eight known compounds, 4 – 11 , were isolated from a MeOH extract of the fern Abacopteris aspera ( Presl ) Ching . Their structures were elucidated on the basis of extensive spectroscopic analysis, including HSQC, HMBC, 1 H, 1 H‐COSY, and NOESY experiments, acid hydrolysis, and by the comparison of their NMR data with those of related compounds.
