Kalanchoe ceratophylla Haw. is a medicinal plant traditionally used to address various health disorders. Its biological activities are believed to be associated with its secondary metabolites, particularly phenolics and flavonoids. Despite its traditional use, scientific information This study assesses the phytochemical composition alongside the total phenolic and flavonoid contents in the stem and leaf preparations of Kalanchoe ceratophylla Haw. Phytochemical screening confirmed the presence of alkaloids, flavonoids, tannins, and phenols in the stem extract, while the leaf extract also contained steroids. The total phenolic content was 7.43 mg GAE/100 g extract for stem and 7.11 mg GAE/100 g extract for leaves, whereas total flavonoids amounted to 0.324 mg QE/g extract (stem) and 1.621 mg QE/g extract (leaves). These findings highlight the potential use of K. ceratophylla, especially its leaves, for developing antioxidant-based herbal medicines.
