Steenis)</em> is one of the plants that is empirically used to treat various diseases. And contains many secondary metabolites, one of which is flavonoid compounds. Binahong leaf <em>(Anredera cordifolia (Ten.) Steenis)</em> has bioactivity as an antioxidant, antibacterial, antifungal, antidiabetic, anti-inflammatory, antiseptic, and antibacterial contains many secondary metabolites, one of which is flavonoid compounds.</p> <p><strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </strong><strong>Methodes</strong>: The leaves used were processed into simplicia by oven heating method with different temperature variations (35<sup>O</sup>C, 50<sup>O</sup>C, 65<sup>O</sup>C) and extracted using 70% ethanol solvent. Furthermore, the identification of flavonoid compounds with the addition of concentrated Mg and HCl powder which is positive for flavonoids if the color is yellow-orange. The determination of the levels of flavonoid compounds was carried out using the UV-Vis spectrophotometric method.</p> <p><strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; R</strong><strong>esults</strong>: Identification tests that have been carried out with ethanol extract of Binahong<em> (Anredera cordifolia (Ten.) Steenis)</em> leaves at 35<sup>O</sup>C, 50<sup>O</sup>C, and 65<sup>O</sup>C positive contain flavonoids seen from the color produced, which is yellow-orange. And the average levels of flavonoids obtained at a temperature of 35<sup>o</sup>C: 2.685% 50<sup>o</sup>C: 2.476% and 65<sup>o</sup>C: 1.980%.</p> <p><strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Conclusion : </strong>The lower the drying temperature of the simplicia, the higher the levels of flavanoid compounds. Variations in simplicia drying temperature had no effect on the presence of flavanoid compounds.</p>}, number={2}, journal={Oceana Biomedicina Journal}, author={Noviyanty, Yuska and Wardania, Oktri and Hepiyansori, Hepiyansori}, year={2023}, month={Jul.} }
