Abstract
Water-distilled essential oil from Salvia umbratica Hance (Labiatae) flowering aerial parts was analyzed by gas chromatography-mass spectrometry (GC-MS). Forty-eight compounds, accounting for 96.77 % of the oil, were identified and the main components of the essential oil of S. umbratica flowering aerial parts were 1,8-cineol (16.74 %), β-caryophyllene (8.42 %), α-thujone (7.80 %), caryophyllene oxide (6.85 %), camphor (6.65 %), and alloaromadendrene (5.60 %) followed by germacrene D (4.29 %) and linalool (4.15 %). The essential oil of S. umbratica possessed contact toxicity against Sitophilus zeamais adults with an LD50 value of 18.12 µg/adult. The oil also showed pronounced fumigant toxicity against S. zeamais with an LC50 value of 10.59 mg/L.
