Leaf Essential Oil

Members of the genus Cinnamomum (Lauraceae) have aromatic volatiles in their leaves and bark and some species are commercially important herbs and spices. In this work, the essential oils from five species of Cinnamomum (C. damhaensis, C. longipetiolatum, C. ovatum, C. polyadelphum and C. tonkinense) growing wild in north central Vietnam were obtained by hydrodistillation, analyzed by gas chromatography and screened for antimicrobial and mosquito larvicidal activity. The leaf essential oil of C. tonkinense, rich in β-phellandrene (23.1%) and linalool (32.2%), showed excellent antimicrobial activity (MIC of 32 μg/mL against Enterococcus faecalis and Candida albicans) and larvicidal activity (24 h LC50 of 17.4 μg/mL on Aedes aegypti and 14.1 μg/mL against Culex quinquefasciatus). Cinnamomum polyadelphum leaf essential oil also showed notable antimicrobial activity against Gram-positive bacteria and mosquito larvicidal activity, attributable to relatively high concentrations of neral (11.7%) and geranial (16.6%). Thus, members of the genus Cinnamomum from Vietnam have shown promise as antimicrobial agents and as potential vector control agents for mosquitoes.

AbstractThe use of synthetic insecticides is responsible for many cases of resistance in insects. Therefore, the use of natural molecules of ecological interest with insecticidal properties turns out to be an alternative approach to the use of synthetic insecticides. This study aims at investigating the larvicidal, adulticidal activity and the composition of the essential oil of Aeollanthus pubescens Benth on the major malaria vector Anopheles gambiae.The leaves of Aeollanthus pubescens were collected in the South of the Republic of Benin. Three reference strains of Anopheles gambiae s.s. such as Kisumu, Kiskdr and Acerkis were used. The chemical composition of the essential oil was analysed by gas chromatography coupled to mass spectrometry. Larvae were exposed to the essential oil extract for 24 h. Adult mosquitoes were exposed to the fragment nets coated with the essential oil for 3 min. Larval mortality and adult survivorship were monitored.Fourteen components were identified representing 98.31% of the total of oil. The major components were carvacrol (51.06 %), thymyle acetate (14.01 %) and γ-terpinene (10.60 %). The essential oil has remarkable larvicidal properties with LC50 of 29.26, 22.65, and 28.37 ppm respectively on Kisumu, Acerkis and Kiskdr strains. With the fragment net treated at 165 µg/cm2, the KDT50 of both Acerkis (1.71 s, p < 0.001) and Kiskdr (2.67 s, p < 0.001) individuals were significantly lower than that of Kisumu (3.77 s). The lifespan of the three mosquito strains decreased respectively to one day for Kisumu (p < 0.001), two days for Acerkis (p < 0.001) and three days for Kiskdr (p < 0.001) compared to their control.Our findings show that the Aeollanthus pubescens essential oil is an efficient larvicide and adulticide against malaria vector Anopheles gambiae. This bioinsecticidal activity is a promising discovery for the control of the resistant malaria-transmitting vectors.
