Callicarpa Species from Central Vietnam: Essential Oil Compositions and Mosquito Larvicidal Activities

There are around 140 species in the genus , with 23 species occurring in Vietnam. The Vietnamese species have been poorly studied. In this work, the leaf essential oils of , , , , , , , and , have been obtained from plants growing in central Vietnam. The chemical compositions of the essential oils were determined using gas chromatography - mass spectrometry. Mosquito larvicidal activities of the essential oils were carried out against . All of the leaf essential oils showed larvicidal activity, but two samples of were particularly active with 48-h LC values of 2.1 and 3.8 μg/mL. essential oil should be considered as a potential alternative mosquito control agent.
