This study was conducted to analyze the fragrance intensity and pattern of the essential oils from aerial parts of 11 species of genus Aster native to Korea. The genus Aster belongs to the Asteraceae family, and plants in the Asteraceae family have been consistently used for food and medicine from the past to the present. In this experiment, the essential oil from aerial parts of 11 species in genus of Aster were used to compare fragrance profiles: Aster tataricus (ATC); Aster hispidus (AHD); Aster ageratoides (AAT); Aster hayatae (AHT); Aster danyangensis (ADG); Aster arenarius (AAR); Aster pseudoglehnii (APN); Aster yomena (AYN); Aster maackii (AMK); Aster incises (AIS); and Aster koraiensis(AKS). The aerial parts of 11 species were harvested at full bloom stage and air-dried in the shade. Essential oils from aerial parts of 11 species of genus Aster was extracted by simultaneous steam distillation extraction (SDE). The extracted essential oil was analyzed by Handheld Odor Meter and Electric nose (E-nose). It was observed that there are differences in fragrance strength among the 11 species cultivated under the same conditions. AAR exhibited the strongest fragrance, followed by ATC, AKS, AMK, and ADG in descending order of intensity. According to the radar plot results of E-nose values, AHD, AHT, AAT, ADG, and ATC displayed similar patterns, while the others exhibited another set of similar patterns. The fragrance pattern of essential oils from the 11 species of genus Aster analyzed by the multivariate statistical methods of principal component analysis (PCA) and discriminant factor analysis (DFA) were almost distinguished based on the species. This study provides basal data for industrial utilization of genus Aster native to Korea in the perfumery and flavoring.
