“…Thirty-one compounds were found. The eight most abundant constituents were consistent with those reported for ginger oil [5], [7], [8], [9], [20], [21], [22]. As compared to values in the literature, the sample was characterized by a very high citral content (24 %) and a neral-togeranial ratio of 0.7.…”

Inhibitory Effects of Ginger Oil on Spontaneous and PGF₂_α-Induced Contraction of Rat Myometrium

Solvent extracts of ginger, the rhizome of Zingiber officinale Roscoe (Zingiberaceae), have been extensively studied for their pharmacological activities in smooth muscles. However, the effects of ginger essential oil on smooth muscle contractility have not been elucidated. The aims of the study were to investigate the effects of ginger oil on rat myometrial contractility. We particularly examined the effects on phasic contractions arising either spontaneously or with PGF (2) (alpha) stimulation. Ginger oil was obtained by hydrodistillation and its constituents analyzed using gas chromatography and mass spectrometry. Rats were humanely killed by asphyxiation with CO (2), and longitudinal uterine smooth muscles were isolated. Isometric force was measured and the effects of ginger oil studied. It was found that citral was the main constituent of ginger oil (24 %). Ginger oil inhibited spontaneous contractions with an IC (50) of 50 microL/100 mL (10 - 150 microL/100 mL). The PGF (2) (alpha)-induced contractions were also significantly reduced by ginger oil. Increases in external calcium concentration completely reversed the relaxant effects of ginger oil. This was the case for both spontaneous and PGF (2) (alpha)-induced contractions. The effects of ginger oil were indistinguishable from those of pure citral. In conclusion, ginger oil is a potent inhibitor of phasic activity in rat uterus, irrespective of how it was produced. Our data suggest that the effects are largely due to citral, and could be via inhibition of L-type Ca channels.

“…The neral-to-geranial ratios reported in the literature for ginger oil vary greatly. The ratios ranged from 0.3 to 4.7 [5], [6], [7], [8]. Factors such as geographical origin and whether the oil is distilled from fresh or dried rhizome material may affect the ratio [9].…”

“…Additionally, among the genotypes included in our study were Hedychium coccineum , H. flavescens and H . flavum whose essential oils have been studied phytochemically [ 18 , 19 ]. The major essential oil components of Hedychium coccineum grown in Mauritius were ( E )-nerolidol (44.4%) and trans -sesquisabinene hydrate (24.2%) [ 19 ].…”

The antimicrobial properties of essential oils have been documented, and their use as “biocides” is gaining popularity. The aims of this study were to analyze the chemical composition and assess the biological activities of Hedychium essential oils. Oils from 19 Hedychium species and cultivars were analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) techniques. The antifungal and insecticidal activities of these oils were tested against Colletotrichum acutatum, C. fragariae, and C. gloeosporioides, and three insects, the azalea lace bug (Stephanitis pyrioides), the yellow fever mosquito (Aedes aegypti), and the red imported fire ant (Solenopsis invicta). Hedychium oils were rich in monoterpenes and sesquiterpenes, especially 1,8-cineole (0.1%–42%), linalool (<0.1%–56%), α-pinene (3%–17%), β-pinene (4%–31%), and (E)-nerolidol (0.1%–20%). Hedychium oils had no antifungal effect on C. gloeosporioides, C. fragariae, and C. acutatum, but most Hedychium oils effectively killed azalea lace bugs. The oils also show promise as an adult mosquito repellent, but they would make rather poor larvicides or adulticides for mosquito control. Hedychium oils acted either as a fire ant repellent or attractant, depending on plant genotype and oil concentration.

Geranyl acetone and nerolidol have a broad spectrum of bioactivity, they exhibit, inter alia, olfactory, germicidal and antimicrobial properties. Twelve E/Z‐mixtures of analogues of geranyl acetone and nerolidol were examined for their odour and antimicrobial activity. Mixtures of analogues of geranyl acetone generally have a scent that is similar to the parent terpenoid, with interesting notes (violet, rose, fruity), while the odour of similar mixtures of nerolidol analogues was rather weak, floral, fresh and fruity. The odour thresholds and relative volatility factors were determined. The antimicrobial activity of products described in this paper, in comparison with nerolidol and geranyl acetone, was similar.
