Essential oil from the aerial part of Plectranthus marrubatus J. K. Morton (Lamiaceae), obtained by hydrodistillation was analyzed by gas chromatography/mass spectrometry (GC/MS) and evaluated for antimicrobial and free radical scavenging activities. Twenty-four compounds representing 99% of the
The essential oils (EOs) of Plectranthus amboinicus showed the highest larvicidal activity among four herbal plants studied and β-caryophyllene might be the major component responsible for its differential toxicity to the larvae of Culex quinquefasciatus and Aedes Aegypti. Mosquitoes act as vectors
BACKGROUND
Anopheles sinensis, Aedes aegypti and Aedes albopictus and Culex pipiens pallens mosquitoes transmit malaria, dengue fever and West Nile virus diseases respectively. This study was conducted to determine the toxicity of 17 constituents from Magnolia denudata seed hydrodistillate (MD-SHD)
