Compound Characterization and Evaluation of Antioxidant Potential of Ethanol Extract Spatholobus littoralis Hassk in Kolaka, Southeast Sulawesi, Indonesia

The bajakah tampala plant (Spahtolobus littoralis Hassk) has been traditionally believed by the public to cure cancer, tumors, heart disease, stroke, and diabetes. However, empirically the public does not yet know the chemical compound content and there have been no studies on biological activity tests, especially the antioxidants of bajakah tampala from Kolaka, Southeast Sulawesi. The aim of this research is a qualitative analysis of the chemical compounds of the ethanol extract of bajakah tampala roots and testing of antioxidant activity. Analysis of the chemical compounds of the ethanol extract of bajakah tampala roots using an FT-IR spectrophotometer and LC-MS/MS. The antioxidant activity of the bajakah tampala root ethanol extract was tested using the DPPH immersion method and the absorption was measured using a UV-Viss spectrophotometer and using the positive control quercetin. The results of the research showed that the ethanol extract of bajakah tampala roots had 8 chemical components that were detected, namely compound 1 apocynoside I, compound 2 quercetin, compound 3 hexosylphingosine, compound 4 3-hydroxy-7-methoxybaicalein, compound 5 momor-cerebroside I, compound 6 ambronal, compound 7 stigmastan-3,6-dione, and compound 8 trilaurin. The ethanol extract of bajakah tampala roots has an antioxidant activity of 21.75 µg/mL which is lower, compared to the antioxidant activity of quercetin of 2.91 µg/mL as a positive control, however the antioxidant activity of the ethanol extract of bajakah tampala roots is still included in the very strong category.
