Various species of Kalanchoe plant has been widely used for traditional medicine and also as an ornamental plant. This research is a continuing search for secondary metabolites from Kalanchoe plants in Indonesia. The fresh leaves of Kalanchoe pinnata (6 kg) was extracted at room temperature with methanol to obtain a concentrated extract. The concentrated extract of methanol was further partitioned successively with n-hexane and ethyl acetate. Yellow solid of pure isolates from ethyl acetate extract was separated by various chromatographic techniques. The chemical structure of isolates was determined by spectroscopic analysis of UV, IR , MS, 1H-NMR, 13C-NMR data and a comparison wih those previously reported on literature and identified as a flavonoid compound 3,3’,4’,5,7 pentahydroxyiflavone also known as kuersetin which belong to the flavonol class.
