Abstract/OtherAbstract:
|
Free radical scavenging activity-guided investigation of the acetone extract of Plectranthus punuctatus (L'Her) (Lamiaceae) resulted in the isolation of a novel diterpenoid 3,11,12,14,19-pentahydroxy-5,8,11,13-abietatraen-7-pyran[4,6]-16-dione whose structure was elucidated based on spectral evidence. The isolated compound showed a significant antioxidant activity in the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and deoxyribose degradation assays with IC50 values of 9.65 microg/mL and 5.25 microg/mL, respectively. |
