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-tetramethyl-indan-1-one and 5-hydroxy-6,7-dimethoxyflavanone, respectively.
