Different plant parts of Ligusticopsis wallichiana (family: Apiaceae) are widely used as traditional medicines. Although many volatile constituents are already identified from the leaves of L. wallichiana, there is no detailed report on the nonvolatile constituents. In the present study, we aimed to isolate and identify the major chemical constituents from the leaves. Bhutkesoside A (1), falcarindiol (2), ferulic acid (3), cnidioside A (4), quercetin 3-O-β-D-glucopyranoside (5), rutin (6), 4′-O-methylquercetin 3-O-β-D-glucopyranoside (7), scopoletin (8), umbelliferone (9), eugenol 4-O-β-D-glucopyranoside (10) and pumilaside A (11) were isolated from the 70% MeOH extract. The structures of isolated compounds were elucidated on the basis of 1H- and 13C-NMR spectroscopic data. Compounds 4–11 are reported for the first time from L. wallichiana. Compounds 5 and 6 showed potent free radical-scavenging activity.
