CHARACTERIZATION OF PHENOLIC ACIDS
AND FLAVONOIDS IN ETHYL ACETATE
FRACTION OF ASTER GLEHNI

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. Phytochem-
icals 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 chromatogra-
phy-tandemmass spectrometry (LC-MS/MS), respectively. Caffeic, ρ-couma-
ric 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 sig-
nificant antioxidant and health-promoting activity, which is attributable to the
high levels of phenolic acids and flavonoids.
