Isolation of Quarcetin-3-O-β-D-glucopyranoside from the ethanol leaf extract of Ficus sycomorous L. (Moracaea)

Ficus sycomorous (Sycamore fig.) Family Moraceae is a plant used in African traditional medicine to treat mental illness, dysentery, cough, diarrhea, tuberculosis and Cancer. In this research work the leaf of the plant was subjected to cold maceration using 75% ethanol. The extract was fractionated using n- hexane, chloroform ethylacetate and n-butanol. The ethylacetate fraction was subjected to column chromatographic separation and purification. Quarcetin-3-O-β-D-glucopyranoside was isolated and the structure of the compound was elucidated by various spectral techniques such as1 and 2D NMR and mass spectrometry.
