Determination of essential oil from Scutellaria baicalensis Georgi (Lamiaceae) by GC-MS, and assessment of its insecticidal properties

Purpose: To isolate essential oil from the aerial parts of Scutellaria baicalensis using GS-MS, and to assess its insect-killing effect against booklice (Liposcelis bostrychophila).Methods: The S. was hydro-distilled subjected gas chromatographic mass spectroscopic (GC-MS) techniques. components with insectkilling potentials were fractionated through bioactivity-guided isolation, isolated screened for their toxic effects on booklice.Results: A total 31 obtained, eugenol as most abundant. When used fumigate baicalensis, two constituents (myristicin eugenol) exerted appreciable effects. Moreover, isolates manifested contact toxicity booklice.Conclusion: These findings indicate insecticidal benefits Liposcelis bostrychophila.
