Testing the Antioxidant and Characteristics of 6-Shogoal and 6-Gingerol in Ginger (Zingiber Officinale)

Ginger is a medicinal plant. The ingredients used in this study included young ginger, old ginger, and bent ginger. In this study, we looked at the results of calculating the antioxidant activation test method in ginger's DPPH, FRAP, and TPC. When comparing antioxidant test methods based on the type of reaction mechanism, antioxidant samples are chosen based on the polyhydroxy or polyphenol structure, the fundamental constituent of natural antioxidants. The FRAP test method yielded 904.27 ± 152.95 for bentung ginger, 858.22 ± 6.58 for young ginger, and 741.88 ± 29.92 for old ginger. The TPC method yielded 488.17 ± 39.41 for old ginger, 443.42 ± 22.41 for old ginger bentung, and 432.61 ± 53.83 for young ginger. The DPPH levels in young ginger are 89.50 ± 0.31, bent ginger is 89.45 ± 0.50, and old ginger is 89.45 ± 0.50. The results showed that old ginger had the highest 6-gingerol compound content (10.37), while young ginger had the highest shogaol content (0.35). The characteristics show that the yield of 6-Ginger for old ginger is higher than that of other ginger, namely 10.37, for young ginger 7.95, and for bentung ginger 8.07. Meanwhile, young ginger has a higher Shogaol yield than other ginger, with 0.34, old ginger 0.32, and Bentung ginger 0.22.
