Kalanchoe blossfeldiana(Crassulaceae} is a succulent plant belonging to the genus Kalanchoe. Various species of Kalanchoe ¬∑plants have been widely used as raw material for traditional medicine and also as an ornamental plant. This study Is a continuation searching for secondary metabolites from Kalanchoe Indonesia plants. Fresh K.blossfeldiana leaves 5.7 kg was extracted with methanolat room temperature to obtain a concentrated extract as much as 155.74 g. Concentrated methanol extract was dissolved in water and then partitioned successively within-hexane and ethylacetate. Ethylacetate extract (20 g) was separated by a combination of chromato.,-aphy on silica and ODS and produced compound 1 (7.1 mB) In the form of a yellow solid, compound 2 (4 mg), and compound 3 (15.4mg) In the form of a white solid. The chemical structures of compounds 1, 2, and 3, were determined by UV spectroscopy, IR, MS, 1H-NMR, 13C-NMR spectroscopy and comparison of data obtained from the literature and Identified as phenolic compounds, namely 3,3′,4′,5,7 pentahydroksl flavonorquercetin (1), epigallocatechlngallate (2), and gallic acid (3).
