Abstract: Column chromatographic study on the aqueous acetone (70%) extract of Paulownia tomentosa (Thunb.) Steud. var. tomentosa fruit led to the isolation of 4 phenylpropanoid glycosides and their structures were determined as verbascoside (1), isoverbascoside (2) campneoside II (3) and isocampneoside II (4) by chemical and spectral analyses. Compounds 1-2 were isolated from the title plant for the first time. The study on antibacterial activity showed that the isolated compounds, acetone extract, EtOAc and H2O fractions exhibited significant inhibition, particularly against Staphylococcus epidermidis.

Key words: Paulownia tomentosa(Thunb.) Steud. var. tomentosa., phenylpropanoid glycoside, antibacterial activity
