Qualitative Phytochemical analysis & determination of antimicrobial activity of Zingiber officinale

Abstract

Numerous nations consume Zingiber officinale on a daily basis. Ginger (Zingiber officinale) is a popular tropical & subtropical shrub medicinal plant. The current study sought to assess the phytochemical composition and antimicrobial properties of Z.officinale extract. Qualitative evaluation of phytochemical tests revealed the existence of saponins, alkaloids, flavonoids, and steroids in ginger extracts in methanol and acetone, as well as the absence of carbohydrate, anthraquinones, and tannin in ginger extracts in methanol and acetone. The antimicrobial properties of Z.officinale extracts in solvents (aqueous, methanol) towards bacteria as well as fungus was investigated. When compared to other concentrations, the highest zone of inhibition was seen in 100µl concentrations of aqueous and methanolic extracts of Z.officinale towards Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Aspergillus flavus, A.niger, and Penicillium sp. This study discovered that the plant possesses excellent metabolites, proving that it has medicinal properties and may be used in daily life
