Isolation and Identification of 4,4′-Diol-2′-methoxychalcone from Leaves of Seabuckthorn

The 4,4′-diol-2′-methoxychalcone was separated from flavonoids in the leaves of seabuckthorn by Gravity-flow Column Chromatography and Silica Gel Column Chromatography. Then its structure was identified and conformed by Nuclear Magnetic Resonance Spectroscopy.
