Abstract

In an ongoing search of compounds from natural sources that exhibit anti-allergic properties, 3 flavonoids were isolated from the ethyl acetatefraction of methanol extracts of gujeolcho (Chrysanthemum zawadskii var. latilobum), with guided histamine release inhibitory effects. The isolated compounds were identified as eriodictyol-7-O-β-d-glucuronide, 5,7-dihydroxy-4-chromene, and 6-methoxyluteolin based on spectroscopic evidences including NMR and MS spectra. These results suggest that gujeolcho extracts and 3 compounds would be candidates as therapeutic or preventive agents for allergic reaction.
