Abstract

Sappan (Caesalpinia sappan L.) is applied as food and traditional medicine. Chinese teak (Senna alexandrina) is a plant from the tropics that can be developed as an antioxidant. This study was conducted to determine the antioxidant activity of the combination of Sappan and Chinese Teak by the DPPH (1,1 Diphenyl 2 Picrylhydrazyl) Free Radical Scavenging method. The extraction method used was maceration with Ethanol 96% as solvent. Determination of antioxidant levels was done quantitatively using the UV-Vis Spectrophotometer instrument at a wavelength of 514 nm. From the results of the study, the regression value obtained for the comparison of Quercetin is y = 3.1303x + 0.2292 with R2 = 0.9974 and IC50 value of 15.899 μg/mL. For the antioxidant activity of Sappan, the regression value y=0.5769x + 18.543 with R2=0.9969 and IC50 value of 54.53 μg/mL, Chinese Teak obtained regression value y=0.1421x + 17.506 with R2=0.9989 and IC50 value of 228.67 μg/mL, and for the combination obtained regression value y=0.4304x + 36.622 with R2=0.9954 and IC50 value of 40.38 μg/mL. The results of this study indicate that the combination of Sappan and Chinese Teak extracts has a very strong antioxidant effect (<50 μg/mL).

Abstract

Kasumba turate flower and Secang lignum have been commonly known as traditional medicinal widely grown in South Sulawesi. Both contain active constituents, including coloring agents such as carthamin in Kasumba turate and brazillin in Secang. These plants have been commonly used in traditional medicine to treat conditions such as high cholesterol, bacterial and viral infections, gout, and as antioxidants. Gout and high cholesterol are closely related. The combination of Kasumba turate and Secang extracts was intended to enhance activity. The evaluation of the xanthine oxidase inhibitor (XOD) and antioxidant activity (AO) was performed using the reducing uric acid and antioxidant FRAP methods. The XOD inhibitory study found that the extracts have activities as follow Sample A, B, C, and Allopurinol of 1.40; 2.1967; 2.24; and 1.39 μg/mL, respectively. The antioxidant capacity of Kasumba turate, Secang extract and their combination was 122.88; 17.36; and 197.31 μg/mL, respectively. We concluded that the combination did not increase the XOD inhibitory and antioxidant capacity. The Kasumba turate extract has the highest activity among the tested extracts.
