Objective To research the chemical constituents from Parathelypteris glanduligera. Methods The compounds were isolated by column chromotography with silica gel, C18 reverse-phase silica gel, and Sephadex LH-20. Their structures were elucidated on the basis of physiochemical prosperities and spectral analysis. Results Eleven compounds were isolated and identified as kaempferol (1), astragaloside (2), trifolioside (3), kaempferol-3-O-α-L-rhamnopyranoside (4), kaempferol-3-O-rutinoside (5), quercetin (6), quercetin-3-O-β-D-galactopyranoside (7), rutin (8), myriciatrin I (9), 3'-methyl-4',6'-dihydroxy-2'-methoxy-chalcone (10), and 3',5'-dimethyl-4',6'-dihydroxy-2'-methoxy-chalcone (11), respectively. Conclusion All compounds are obtained from this plant for the first time.
