Essential oil of ginger [Zingiber officinale Roscoe]

The compounds in Ginger (Zingiber officinale-Roscoe) essential oil provenience China and wild oregano (Origanum vulgare) essential oil of Romanian origin were identified by GC/MS and their antioxidant and antifungal properties were evaluated. Wild oregano oil was characterized by high content of oxygenated monoterpenes hydrocarbons (84.05%) of which carvacrol was the most abundant (73.85%) followed by b-linalool (3.46%) and thymol (2.29%). Ginger oil had a higher content of sesquiterpene hydrocarbons including zingiberene (31.47%), b-sesquiphellandrene (13.76%), a-curcumene (10.41%), a-farnesene (8.31%) and b-bisabolene (7.55%) but a lower content of oxygenated monoterpenes (7.97%). The high content of oxygenated monoterpens of wild oregano oil is in accordance with total content of polyphenols determined by the Folin�Ciocalteu method (6.71�0.73 mg of gallic acid equivalent per g oil). Ginger oil had only 1.34�0.22 mg gallic acid equivalent per g oil. Wild oregano oils exhibited appreciable in vitro antioxidant activity as assessed by 2, 2`-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and 2,2�-azino-bis (3 ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS). The sample concentration required to scavenge 50% of the DPPH free radicals was 0.76�0.13 mg/mL for wild oregano oil compared to 20.22�2.12 mg/mL for ginger oil. Also, wild oregano oils showed significant inhibitory activity against selected pathogenic fungi (Fusarium oxysporum, Aspergillus flavus and Penicillium expansum). 1�L of oregano oil is sufficient for almost 75% growth inhibition of Aspergillus flavus compared to ginger oil which shows antifungal activity at 240�L for 78% growth inhibition. It can be concluded that wild oregano oil could be used as food preservative in some food products in which Fusarium oxysporum, Aspergillus flavus and Penicillium expansum could grow and have potential to produce health hazards mycotoxines.

Abstract Ginger (Zingiber Officinale Roscoe) has been known reduce muscle pain after exercise, and 6-shogaol {(E)-1-(4-Hydroxy-3-methoxyphenyl)dec-4-en-3-one)} is the major essential oil contained in ginger. In this study, the protective effect of 6-shogaol on L6 muscle cells against oxidative damage was measured. 6-shagol inhibited the damage of L6 cell induced by H2O2, and allowed the increase in mRNA and protein expression levels of intracellular HO-1 and NRF2. 6-shogaol also reduced the production of intracellular ROS. These results suggested that 6-shagol effectively inhibits oxidative damage of skeletal muscle cell.

The chemical composition of the essential oil from the rhizome of ginger ( Zingiber officinale Roscoe), collected from Nahan, Himachal Pradesh, India, was determined by gas chromatography and GC-MS. Fifty-one compounds, representing 95.1% of the oil, were identified. The oil was characterized by relatively large amounts of the monoterpenoids 1,8-cineole (10.9%), linalool (4.8%), borneol (5.6%), α-terpineol (3.6%), neral (8.1%), geraniol (14.5%), geranial (9.5%), trans-dimethoxy citral (5.0%) and geranyl acetate (6.3%). Five compounds, namely trans-linalool oxide, trans-linalool oxide acetate, ( Z)-dimethoxycitral, ( E)-dimethoxy citral and epi-zingiberenol are reported for the first time in oil of ginger.

Red ginger extract has a category strong antibacterial effect on Staphylococcusaureus and Streptococcus mutans. Red ginger essential oil has the potential forstronger inhibition. This study aims to compare the antibacterial effectiveness of redginger essential oil against Staphylococcus aureus and Streptococcus mutans. Thedesign of this study was a laboratory experimental design with a factorial completelyrandomized design. The red ginger used in this study was proven to be a species ofZingiber officinale Roscoe. The production of essential oils in this study uses thesteam distillation method. The content of secondary metabolites in red ginger wastested quantitatively by the GC-MS method. Determination of antibacterial activityusing the disc diffusion method. The data were processed using the SPSS 21.0program. The normality of data distribution was tested with the Shapiro-Wilk test,followed by one-way ANOVA, Levene's test, and the Tukey HSD Post Hoc Test. Theresults of the antibacterial test of red ginger essential oil against Staphylococcusaureus (21.21mm ± 0.315) and Streptoococcus mutans (23.43mm ± 0.189) provedthat the inhibition power of the category was very strong at a concentration of 75%.

The dried rhizomes of ginger (Zingiber officinale Roscoe) yield, to acetone, a complex mixture of substances including a series of S-(+)- gingerols (i.e. 1-(4?- hydroxy-3?-methoxyphenyl)-5-hydroxyalkan-3-ones) with 10,12, and 14 carbon atom side-chains, essential oil, palmitic and other fatty acids, and other unidentified substances. The substances, shogaol and zingerone, described by Nomura as ginger constituents appear to be absent but are formed by the action of alkalis or heat on gingerol or the oleoresin. The gingerol with the 11-carbon side-chain, claimed by Lapworth, Pearson, and Royle as the principal pungent substance in ginger, is also absent. Ginger oleoresin may be qualitatively analysed by thin-layer chromatography on silica gel with hexane-ether (1 : 1).
