title: Characteristic aroma-active compounds of Korean perilla (Perilla frutescens Britton) leaf.
abstract: Aroma-active compounds from Korean perilla (Perilla frutescens Britton) leaf were extracted by solvent-assisted flavor evaporation (SAFE), liquid-liquid continuous extraction (LLCE), and hydrodistillation (HD) and analyzed by gas chromatography-mass spectrometry (GC-MS) and gas chromatography-olfactometry (GC-O). Thirty-three volatile compounds were identified by GC-MS. 1-(3-Furyl)-4-methyl-1-pentanone (perilla ketone) was found to be the most abundant volatile compound, followed in order by (Z)-3-hexenol and 1-octen-3-ol. Perilla ketone comprised 81% (93 ppm), 84% (120 ppm), and 95% (490 ppm) of the volatile compounds obtained from SAFE, LLCE, and HD, respectively. Thirteen aroma-active compounds were detected by GC-O. Perilla ketone, 1-(3-furyl)-4-methyl-3-penten-1-one (egoma ketone), and 1-(3-furyl)-4-methyl-2-penten-1-one (isoegoma ketone) were considered to be the characteristic aroma-active compounds of Korean perilla leaf. Perilla ketone, (Z)-3-hexenal (green), egoma ketone, and isoegoma ketone were the most intense aroma-active compounds in Korean perilla leaf. Other relatively intense odorants included (Z)-3-hexenol (green), (E)-2-hexenal (green), benzaldehyde (almond), 1-octen-3-one (metallic), 1-octen-3-ol (mushroom), phenylacetaldehyde (honeysuckle), linalool (lemon), and beta-caryophyllene (woody).
