Two new sesquiterpene glucosides from Dennstaedtia scabra (Wall.) Moore.
Two new sesquiterpene glucosides onitioside A (1) and dennstoside B (2), were isolated from the 95% EtOH extract of Dennstaedtia scabra (Wall.) Moore, together with seven known compounds, onitisin (3), pterosin A (4), pinocembrin (5), pinocembrin 7-rutinoside (6), kaempferol (7), nicotiflorin (8), and galangin (9). Their structures were determined by extensive spectroscopic analysis.
