Ipomoea aquatica is used in Indian system of medicine and many pharmacological activities have been attributed to it. The preliminary phytochemical screening revealed presence of polyphenolic compounds in it. The hydroalcoholic extracts of leaves of Ipomoea aquatica was studied for isolation of flavonoid by chromatographic method. On the basis of study of physical properties, chemical tests and spectroscopic evaluation (UV, IR, 1HNMR and Mass Spectrometry) the structure of the isolated compound was established. The isolated compound was yellow colored and soluble in methanol, ethanol and dimethyl sulfoxide, having melting point range 315-317oC. Interpretations of all the spectra revealed that the isolated compound was quercetin. Thus it was concluded that many pharmacological activities reported on this plant may due to presence of quercetin.
