Abstract
Binahong Anredera cordifolia (Tenore) Steenis leaves contain chemical compounds that can be used as antioxidants. This study aims to examine the phytochemical and antioxidant activity of the ethanol extract of binahong leaves. Binahong leaves were extracted using the maceration method with an ethanol solvent. The phytochemical test showed that the ethanol extract of binahong leaves contained phenolic compounds, flavonoids, alkaloids, and tannins to have potential antioxidants. The antioxidant activity test was carried out using the DPPH method and absorbance measurement with a UV-Vis spectrophotometer at a wavelength of 517 nm. The results showed that the ethanol extract of binahong leaves had strong antioxidant activity, as evidenced by the IC50 value of 87.423 µg/mL.
Highlights
Binahong is cultivated as herbal medicine, planted in pots, in the yard, or garden
The materials used in the study were binahong (Anredera cordifolia (Tenore) Steenis) leaves, 1,1-diphenyl-2-picrylhydrazyl (DPPH), 96% of ethanol, FeCl3, HCl, Mg powder, distilled water, Mayer's reagent, and quercetin
The presence of antioxidant activity from the sample results in a color change from purple to yellow. This change occurs when DPPH free radicals are captured by antioxidants and release hydrogen atoms to capture stable DPPH-H
Summary
Binahong is cultivated as herbal medicine, planted in pots, in the yard, or garden. Binahong leaves are often used as a traditional medicine to heal burns, rheumatism, gout, lack of appetite, nosebleeds, inflammation of the kidneys, colitis, and cancer. The binahong plant's benefits have not been widely known in Indonesian society [1]. Tannins, flavonoids, alkaloids, and polyphenols with antioxidant properties [2]. Antioxidants have an important role to play in maintaining health. It is due to the ability of antioxidants to scavenge free radicals. Free radicals are highly reactive because they have one or more unpaired electrons. Reactive oxygen compounds are produced continuously in the human body due to normal metabolic processes [3]
