Four compounds were isolated from the roots of Dipsacus asper roots, and were identified as methyl 3,5-di-O-caffeoyl quinate, 3,5-di-O-caffeoyl quinic acid, sitosterol $3-O-{eta}-D-Glucopyranoside$ and hederagenin $3-O-{alpha}-L-arabinopyranoside$. Among the isolated compounds, methyl 3,5-di-O-caffeoyl quinate and 3,5-di-O-caffeoyl quinate acid have never been reported previously from this plant.
