The essential oils from aerial parts of Scutellaria laeteviolacea was analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The characteristic odor components were also detected in the oil using gas chromatography-olfactometry (GC-O) analysis and aroma extraction dilution analysis (AEDA). As a result, 100 components (accounting for 99.11 %) of S. laeteviolacea, were identified. The major components of S. laeteviolacea oil were found to be 1-octen-3-ol (27.72 %), germacrene D (21.67 %),and β-caryophyllene (9.18 %). The GC-O and AEDA results showed that 1-octen-3-ol, germacrene D, germacrene B, and β-caryophyllene were the most characteristic odor components of the oil. These compounds are thought to contribute to the unique flavor of this plant.
