Abstract: Three diterpenoids <i style="">p</i>-benzochinone, labda-14-en-8,13-diol, coleon U 12-methyl ether, a triterpenoid ursolic acid and two sterols have been isolated and identified from the roots of<i style=""> Nepeta clarkei </i>Hook.f. The antioxidant activities of four isolates have also been determined, of which, coleon U 12-methyl ether and <i style="">p</i>-benzochinone have shown good DPPH scavenging activity with IC<sub>50</sub> value 0.045 mg/mL and 0.059 mg/mL, respectively.
