Abstrakt: The leaf oil compositions of two Lauraceae and one Annonaceae plants cultivated in Vietnam were analysed by GC/MS (gas chromatography-mass spectrometry) analysis. The leaf oil of the first Lauraceae plant Cinnamomum melastomaceum contained 34 identified compounds, in which benzyl benzoate (38.5 %), linalool (19.9 %), (E)-caryophyllene (10.5 %), and α-terpineol (6.9 %) were the major compounds. The leaves of the second Lauraceae plant Neolitsea buisanensis gave an oil with the main compounds (E)-β-ocimene (24.0 %), benzyl benzoate (15.8 %), bicyclogermacrene (14.9 %), and (E)-caryophyllene (6.3 %). The leaf oil of the Annonaceae plant Uvaria microcarpa consisted of the principal compounds (E)-caryophyllene (18.0 %), bicyclogermacrene (8.1 %), and δ-elemene (6.1 %). Two Lauraceae oil samples exhibited strong mosquito larvicidal activity against Aedes aegypti, Ae. albopictus, and Culex quinquefasciatus with LC 50 and LD 90 values of less than 50 μg/mL. The Annonaceae oil sample showed strong antimicrobial activity against the fungus Aspergillus niger ATCC 1015 with the MIC (minimum inhibitory concentration) value of 32 μg/mL. In the docking approach, the major compounds (E)-caryophyllene, bicyclogermacrene, and benzyl benzoate interacted with the mosquito odorant-binding protein 3OGN, whereas (E)-caryophyllene, bicyclogermacrene, and δ-elemene also potentially interacted with the 4ZA5 protein of fungus A. niger.
