Quality Assessment of <i>Zingiber officinale</i> Roscoe Essential Oil from Nepal

Zingiber officinale Roscoe rhizome plays a vital role in food flavoring as well utilization folk medicine. Nepal is categorized among the leading countries of Z. production and export. Mature collection based on major sites within Nepal, but we are currently unaware chemical composition essential oil for A comparative investigation compositions, collected from 12 different eastern, mid, western regions has been carried out. The analysis oils by gas chromatographic–mass spectral (GC-MS), enantiomeric chiral chromatography–mass spectrometry (CGC-MS), antimicrobial activity was evaluated. Essential yields ranged 0.28% to 0.34%. results showed that obtained this study contained α-zingiberene (8.6%-24.1%), camphene (7.2%-12.8%), β-phellandrene (3.8%-10.1%), neral (0.6%-11.8%), geranial (1.0%-17.4%), ar-curcumene (3.0%-10.3%), β-sesquiphellandrene (3.7%-9.7%). With CGC-MS, distributions 21 compounds were determined no contrasting distributions. Two samples (G3 G5) possessed good antibacterial against Pseudomonas aeruginosa (MIC = 78.1μg/mL) excellent antifungal Aspergillus niger 39.1 μg/mL). Based content citral (neral geranial), their respective areas might be used identify an ideal zone Nepal.
