Abstract

The leaves of the kopasanda plant (Chromolaena odorata L.) contain alkaloids, flavonoids, saponins, terpenoids and tannins which have the potential to be anti-diabetic and anti-cholesterol. In vitro research has been carried out on the ethanol extract of kopasanda leaves (Chromolaena odorata L.) to determine the potential of α-glucosidase enzyme inhibitor compounds as antidiabetic by determining the IC50 value and the potential to reduce cholesterol levels as an anticholesterol by determining the EC50 value. Testing for the inhibitory activity of the α-glucosidase enzyme used the spectrophotometer method with a microplate reader at a wavelength of 405 nm, with acarbose as a comparison. The results showed that the activity of the ethanol extract of kopasanda leaves (Chromolaena odorata L.) as an inhibitor of the α-glucosidase enzyme obtained an IC50 value of 444.019 µg/mL in the very weak category. In testing the anti-cholesterol potential using a UV-Vis spectrophotometer with measurements at a wavelength of 672 nm, the calculation results obtained an EC50 value of 1,017.118 µg/L. This shows that the activity of the ethanol extract of kopasanda leaves (Chromolaena odorata L.) has the potential to inhibit cholesterol.

Abstract

Button mushrooms (Agaricus bisporus) are plants that contain phenols as antioxidants. Antioxidants are electron donor or reductant compounds. These compounds have a small molecular weight but are able to inhibit the development of oxidation reactions by preventing the formation of radicals. phenol is the main antioxidant component found in Agaricus bisporus extracts.  The aim of this research is to determine the antioxidant activity value of button mushroom ethanol extract (Agaricus bisporus) using the method of ferric reducing antioxidant power (FRAP). This research uses the maceration method as an extraction process using 96% ethanol. The resulting filtrate was concentrated with a vacuum rotary evaporator to produce a thick extract. Antioxidant testing was carried out using the FRAP method with a reagent solution of potassium feryricide, phosphate buffer pH 6.6 tricloroacetic acid (TCA), aquadest, and iron 3 chloride (FeCl3). Samples were analyzed using a UV-Vis spectrophotometer at a wavelength of 725 nm using quercetin as a standard solution. The results showed that the antioxidant activity value of the button mushroom ethanol extract (Agaricus bisporus) with the FRAP method was 3.847 mg QE /g extract.
