Key Word Index - Onychium siliculosum; Pteridaceae; pterosins; flavonones; structure elucidation. Two new compounds, onitinoside and onysilin along with the known compounds, pinostrobin, onitin, onitisin, campesterol, sitosterol and n-alkanes (C25-C33) were isolated from Onychium siliculosum.Onitinoside and onysilin were identified by spectral and chemical methods as 4-O-glucosyl-6-(2'-hydroxyethyl)-2,2,5,7-tetramethylindan-1-one and 5-hydroxy-6,7-dimethoxyflavonone, respectively.
