Chemical Composition and In Vitro Cytotoxicity of

Aug 26, 2015 · However, major differences between the chemical composition of the leaf and flower oil was recorded in the present study. 1,8-Cineole, -phellandrene, -terpinene, p-cymene, isoamyl acetate, isobutyl isobutyrate and in general linear compounds and oxygenated monoterpines were more in the oil of flowers as compared to leaf . Chemical Compositions of Crassocephalum crepidioides Jun 10, 2019 · The mosquito larvicidal activities of aerial parts (leaves and stems) essential oil of C. crepidioides are summarized in Table 2.The essential oil showed excellent larvicidal activity against all 3 mosquito species tested, comparable to many other essential oils screened for mosquito larvicidal activity. 25,26 The larvicidal activities of the essential oil of C. crepidioides are likely due to

Chemical Compositions, FTIR and Larvicidal Activity of

Aug 31, 2019 · complex mixtures whose composition varies. In this study, the chemical composition, and larvicidal activity of extracted essential oils from some aromatic plants were evaluated. Modified steam distillation apparatus was used to extract essential oils from the Citrus limon linn leaf, Vitex trifolia seed and Cananga odorata. Furthermore, the plant materials were tested using Chemical composition and larvicidal activities of Azolla Nov 06, 2018 · Next, the maceration extraction method has a higher percentage of neophytadiene (27.852%), hexadecanoate <methyl> (14.182%) and phytol (10.043%), with a total of 52% of all three compounds. Neophytadiene, hexadecanoate and phytol were used in many studies for larvicidal activity [ 59 61 ]. Chemical composition and larvicidal activity of essential May 01, 2020 · Larvicidal activity and its relationship with the composition of the essential oils Table 2 shows the larvicidal activity of the essential oils, the oxygenated monoterpene thymol, the phenylpropanoid eugenol and the organophosphate insecticide chlorpyrifos on the early fourth instar larvae of A. aegypti .
