nivea flowering aerial parts has a potential for development into a natural insecticide/fumigant for control of insects in stored grains.Įnergy Technology Data Exchange (ETDEWEB) zeamais with an LC50 value of 8.89 mg/L.Conclusion: The study indicates that the essential oil of S. The essential oil also possessed fumigant toxicity against S. zeamais with an LD50 value of 10.56 mug/adult. nivea exhibited strong contact toxicity against S. The principal compounds in the essential oil were (+-limonene (15.46%, caryophyllene oxide (7.62%, linalool (7.20%, alpha-pinene (6.43%, beta-pinene (5.66% and spathulenol (5.02% followed by beta-eudesmoll (4.64% and eudesma-4,11-dien-2-ol (3.76%. A total of 43 components of the essential oil of S. nivea flowering aerial parts was obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS. nivea Turcz (Asteraceae aerial parts against maize weevils (Sitophilus zeamais Motschulsky for the first time.Results:Essential oil of S. The aim of this research was to determine chemical composition and insecticidal activity of the essential oil of S. There is no report on medicinal use of S. GC-MS Analysis of Insecticidal Essential Oil of Flowering Aerial Parts of Saussurea Nivea Turczįull Text Available Background:Several species from Saussurea have been used in the traditional medicine, such as S. latifolius aerial parts has a potential for development into a natural insecticide/fumigant for control of insects in stored grains. The study indicates that the essential oil of E. zeamais with an LC50 value of 9.98 mg/L. The essential oil also exhibited fumigant toxicity against S. zeamais with an LD50 value of 36.40 µg/adult. latifolius possessed contact toxicity against S.
A total of 35 components of the essential oil of E. latifolius aerial parts at flowering stage was obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS. latifolius aerial parts against maize weevils (Sitophilus zeamais Motschulsky for the first time. The aim of this research was to determine chemical composition and insecticidal activities of the essential oil of E. However, no report on chemical composition and insecticidal activities of the essential oil of this plant exists. GC-MS Analysis of Insecticidal Essential Oil of Aerial Parts of Echinops latifolius Tauschĭirectory of Open Access Journals (Sweden)įull Text Available The roots of Echinops latifolius Tausch (Asteraceae have been used in the traditional medicine. Insecticidal activity of the essential oil .
Gas chromatography/mass spectrometric (GC/MS) analyses (HP-5MS column) of the essential oil were performed and its composition determined. scandens was carried out using Clavenger apparatus in order to obtain the volatile oils. Methods: Steam distillation of the aerial parts of P. GC-MS Analysis of Insecticidal Essential Oil of Aerial Parts of.
