Popis: In search of plants rich in phenolics in Egypt, Kalanchoe marmorata Baker was subjected to phytochemical study. The preliminary phytochemical screening revealed its richness in phenolics. Fractionation of the lyophilized aqueous extract of the leaves of K. marmorata by different organic solvents successively resulted in the isolation and purification of five compounds from the ethyl acetate soluble fraction. These compounds namely; E1 isorhamnetin-3-O-α-l-1C4-rhamnopyranoside; E2 quercitin; E3 4′-methoxy-myricetin-3-O-α-l-1C4-rhamnopyranoside; E4 Quercitin-3-O-β-d-4C1-glucopyranoside and E5 protocatechuic-4′-O-β-d-4C1-glucopyranoside, were identified by analysis of their spectral data including 1H NMR and 13C NMR.
