摘要： The odor properties of samples extracted from the aril of the Chinese traditional medical plant Torreya grandis by hydrodistillation (HD), supercritical fluid carbon dioxide extraction (SFE) and solvent extraction (SE) were investigated by a trained panel applying quantitative descriptive analysis (QDA) with a 5-point intensity scale. At the same time, the volatile profiles were studied by in-tube extraction and direct thermal desorption gas chromatography equipped with flame ionization detector and hyphenated to mass spectrometry (ITEX-GC-FID/MS). The SE sample showed most a unpleasant "sweaty, pungent" odor, while the SFE sample exhibited an appreciated "citric, sweet, floral" odor, and the HD sample was distinguished by its "minty" sensory attributes. Moreover, the HD sample was characterized by the highest concentration of oxygenated monoterpenes (7.9%), while the SFE sample had the highest relative content of sequiterpenes (23.6%). On the other hand, the SE sample was distinguished by the high amount of aliphatic acids (0.8%). The significant difference in the odor properties of the three extracts is attributed to the large diversity in their compositions.
