Ginger (Zingiber officinale), a well-known medicinal plant used in traditional medicine, has
been studied for its potential antibacterial and antioxidant properties. This study evaluated the
phytochemical profile, antioxidant activity, and antibacterial efficacy of methanol and aqueous
ginger rhizome extracts. Phytochemical screening confirmed the presence of vital bioactive
compounds such as flavonoids, alkaloids, glycosides, phenols, and saponins, with methanol
extracts demonstrating higher bioactive content. Antioxidant capabilities were measured using
DPPH radical scavenging assay, revealing that methanol extracts exhibited strong antioxidant
activity (98.60% at 400 µg/mL) with an IC50 of 9.06 µg/mL, while aqueous extracts showed
96.15% scavenging activity and an IC50 of 6.22 µg/mL. Antibacterial activity was evaluated
using the Minimum Inhibitory Concentration (MIC)
