Abstract:

Aster glehni is widely distributed in Korea. However, detailed information on phenolic compounds of this plant are lacking. We identified phenolic acids and flavonoids in an ethyl acetate extract of Aster glehni. Phytochemicals were extracted from leaves into methanol, and an ethyl acetate extract was subsequently prepared. Phenolic acids and flavonoids were identified via gas chromatography-mass spectrometry (GC-MS) and liquid chromatography- tandem mass spectrometry (LC-MS/MS), respectively. Caffeic, ρ-coumaric acid, protocatechuic acid, 4-hydroxybenzoic acid, and salicylic acid were the major phenolic acids, and the levels of astragalin, hyperoside, kaempferol, and rutin were the highest among the 9 identified flavonoids. These results suggest that the ethyl acetate fraction of Aster glehni leaves may exhibit significant antioxidant and health-promoting activity, which is attributable to the high levels of phenolic acids and flavonoids.
