Phytochemical Investigation of Ginger: Unveiling Therapeutic Compounds With Multiple Health Applications

Ginger, a vital food component, has a long history of usage in various forms of traditional and alternative medicine with numerous health benefits. Ginger (Zingiber officinale Roscoe) is considered herbal medicine, being a safer alternative with manifold active and harmless ingredients. The primary aim of this research was to conduct a phytotherapeutic profiling and potential evaluation of essential oil and aqueous extracts derived from ginger rhizomes. The rhizomes were acquired from a local market in Lahore, Punjab, Pakistan. Essential oil extraction was performed using a hydrodistillation method, yielding conc. from 200 to 3.125 mg/mL. Results indicated that both the essential oil and aqueous extracts possessed substantial total phenolic content. Furthermore, DPPH radical scavenging activity was notable at 200 mg/mL, with the essential oil showing 80.54% ± 1.36% and the aqueous extracts at 90.06% ± 0.85%. The extracts also demonstrated potent antibacterial activity against Azospirillum lipoferum and antifungal activity against Trichoderma hamatum (24 ± 2) at 200 mg mL^-1 in comparison to standard antibiotics. Moreover, the essential oil extracts exhibited promising antidiabetic and anti-inflammatory (83.33 ± 0.90) properties compared to commercial drugs. Gas chromatography-mass spectrometry (GCMS) and liquid chromatography-mass spectrometry (LCMS) analyses revealed the presence of multiple phytotherapeutic compounds, viz, trihexyl(tetradecyl)phosphonium bis[(trifluoromethyl)sulfonyl]imide, heptatetracontylcyclohexane, 3,5-dihydroxybenzyl alcohol, tris(heptafluorobutyrate), tetratriacontane, 17-hexadecyl-, and 1-deoxy-1-(methylamino)-D-galactitol, N,O,O,O,O,O-hexa(trifluoroacetyl)-, which have not been reported in Z. officinale previously. Thus, the plant is a highly valuable resource for the pharmaceutical industry as a safer alternative to conventional drugs.
