Abstract
Background: Mango plants are popular in Indonesia and originate from Southeast Asia, having been cultivated for thousands of years. Kiojay mango (Mangifera indica var. Kiojay), a variety from Thailand, is recognized in Indonesia for its potential use as an herbal medicine. Research has shown that mango leaf extracts contain bioactive compounds, such as flavonoids, which exhibit antimicrobial, antiinflammatory, and antioxidant properties. Research Objectives: To determine the flavonoid content in the ethanol extract of Kiojay mango leaves (Mangifera indica var. Kiojay) using UV-Vis spectrophotometry. Research Method: The research began with maceration using 96% ethanol as the solvent. The extract underwent specific standardization tests, including organoleptic analysis and secondary metabolite screening via test tube methods. Non-specific standardization was conducted to determine water content, total ash content, and acid-insoluble ash content. Flavonoid quantification was performed using UV-Vis spectrophotometry. Results: The maceration process of kiojay mango leaves yielded a 12.363% extract. Specific standardization showed that the extract was viscous, had a characteristic mango odor, a dark brown color, and a bitter taste. It tested positive for tannins and flavonoids (12.280 mg QE/g ± 0.067) but negative for alkaloids, saponins, and terpenoids. Non-specific standardization revealed a water content of 7.66%, total ash content of 5.00%, and acid-insoluble ash content of 2.91%. Conclusion: The ethanol extract of Kiojay mango leaves (Mangifera indica var. Kiojay) has been standardized and positively identified to contain flavonoids through secondary metabolite screening. The average flavonoid content was 12.280 mg QE/g ± 0.067. Recommendation: Future research should focus on identifying and characterizing secondary metabolites, comparing flavonoid content among mango varieties, and exploring the health benefits of Kiojay mango leaves to optimize their use in traditional medicine.
