Abstract
The leaves of Paulownia coreana Uyeki were collected, extracted with acetone-$H_2O$ (7:3, v/v), concentrated under reduced pressure and successively fractionated using n-hexane, methylene chloride, ethyl acetate and water on a separatory funnel. A portion of the ethyl acetate soluble powder was chromatographed on a Sephadex LH-20 column using aqueous methanol and ethanol-hexane as washing solvents. Two isomeric phenylpropanoid glycosides were isolated and elucidated as verbascoside and isoverbascoside by NMR and MS spectrometers.
