摘要

The present study was conducted to investigate the antioxidant and radical scavenging activities of essential oils of four Lamiaceae plants i.e. Pogostemon cablin, Lavandula angustifolia, Melissa officinalis, and Salvia officinalis native to Pakistan. The essential oil contents from the aerial parts of P. cablin, L. angustifolia, M. officinalis and S. officinalis were found to be 1.98, 0.58, 0.25 and 0.46%, respectively. The principal chemical constituent established in P. cablin L. angustifolia, M. officinalis, and S. officinalis essential oils, were patchouli alcohol, linalool, citronellal, and 1,8-cineol, respectively. The antioxidant activity was evaluated by scavenging of 2,2-diphenyl-1-picryl hydrazyl radical (DPPH center dot), percent inhibition of linoleic acid oxidation and bleaching beta-carotene in linoleic acid system. The essential oils possessed appreciable antioxidant and radical scavenging activities revealing potential for therapeutic applications.
