Abstract:
Based on IDF 6.7 million people deaths due to diabetes mellitus in 2021. Current study showed that dietary of fruits and vegetables containing antioxidant have associated with the reduction of the risk of many chronic diseases such as diabetes and cardiovascular. Plant phenolic compounds can act as antioxidant individually or in combination. Zingiber officinale Roscoe, Caesalpinia sappan, and Cinnamomum burmannii have phenolic compounds. However less information about antioxidant activity of ginger in this combination especially in decoction extraction method. This research was descriptive quantitative and aim at determining the content of phenolic compound and antioxidant activity of three varieties of ginger (Zingiber officinale Roscoe) combination with Cinnamomum burmannii and Caesalpinia sappan in decoction extraction method. Phenolic compound test was conducted by utilizing Folin-Ciocalteu method; while antioxidant activity test was performed by DPPH method. Both tests used Spectrophotometer UV-Vis. Based on ANAVA and independent t test combination of three varieties of ginger have higher total phenolic (38.80±0.217, 39.34 ± 1.02, 39.99± 0.44) than of non-combination (21.222±0.25, 21.36±0.60, 23.58±1.02). Three varieties of ginger combination have antioxidant activity higher (75.64 %, 68,97 %, 61,45 %) than ginger without combination (68.39 %, 60.29 %, 51.55%). Conclusion of this research is total phenolic content and antioxidant activity of ginger combination higher than in non-combined ginger, therefore ginger combination can be antidiabetic candidate.
