Discovery and Analysis of Antioxidant-Packed Compounds from Ginger
Main Article Content
Abstract
Introduction: The Southeast Asian perennial ginger (Zingiber officinale Roscoe) is rich in bioactive substances including zingerone, which have antibacterial, anticancer, anti-inflammatory, and antioxidant qualities. The medicinal potential of gingerone is supported by its phenolic structure, which makes it a less risky and less side effect-prone treatment than traditional methods. This study investigates the pharmacological characteristics of zingerone, providing information for the creation of plant-based treatments.
Objective: This study aims to explore the effects of various extraction solvents and drying techniques on the antioxidant characteristics of bentong ginger (Zingiber officinale). The study evaluates extracts made by sun, oven, freeze, and vacuum drying with ethanol, aqueous ethanol, and hot water as solvents. It also evaluates the radical scavenging abilities of DPPH• and ABTS•+ and the Ferric Reducing Antioxidant Power (FRAP).
Methods: This study investigates how Bentong ginger's (Zingiber officinale) antioxidant qualities are affected by drying techniques and extraction solvents. We measured the Total Antioxidant Activity (TAA), the DPPH• and ABTS•+ radical scavenging, the Ferric Reducing Antioxidant Power (FRAP), and the ethanol, aqueous ethanol, and hot water solvents in extracts that were dried in the sun, oven, freeze, and hoover.
Results: The result demonstrate that sun-drying and freeze-drying enhance antioxidant activity, with ethanol and aqueous ethanol being the most effective solvents. Strong positive correlations were found between Stronger associations were seen between total phenolic content (TPC) and total flavonoid content (TFC) and FRAP and TAA, but not with radical scavenging capabilities.These findings highlight the effectiveness of sun-drying and freeze-drying combined with ethanol extraction for maximizing ginger's antioxidant potential.
Conclusion: Research on Zingiberaceae medicinal plants reveals significant antioxidant properties, with high levels of flavonoids, phenolics, and terpenoids contributing to their effectiveness. These findings support their traditional medicinal uses and suggest potential for modern pharmaceutical and nutraceutical applications. Future studies should explore in vivo effects and clinical trials to further validate their antioxidant potential and develop natural therapies.
