“…The moisture content of the ginger sample was 10.20%. This amount was different from the reports from Otunola et al (2010), Ugwoke and Nzekwe (2010) and Ajayi et al (2013) which were 6.37%, 6.45% and 4.63% respectively. The differences may depend on the temperature and duration of drying.…”

The essential oils and fatty acids composition of stored Zingiber officinale Roscoe (Ginger) were characterized using Gas chromatographic-Mass Spectrometric (GC/MS) method. The ginger rhizomes sample was procured from spices store at Bwari main market, Abuja, Nigeria. It was pretreated and the proximate analysis was carried out. The essential oils and fatty acids were extracted using Hydro-distillation unit. It was then analyzed using GC/MS. From the results obtained, the proximate composition showed 8.50% protein content, 3.80% crude fibre, 5.10% fat, 3.60% ash content, 10.20% moisture and 68.80% carbohydrate content. 38 essential oil components were found and the essential oil was dominated by the compound class Sesquiterpenes (64.83%) followed by Esters (13.29%), aldehydes (9.16%), Sesquiterpenols (6.46%) and monoterpenes (5.71%). Monoterpenols constituted 3.35% while ketones and oxides were seen in trace amounts. The specific dominant constituents were zingiberene (28.57%), Arcurcumene (14.22%) and Geranyl Acetate (13.28%). There was a decrease in the number of sesquiterpenes and monoterpenes in the stored ginger compared to the number earlier reported on freshly harvested and dried samples but the reduction did not affect the overall average percentage composition. The fatty acid comprised 50% saturated acids and 50% unsaturated acids and was dominated by Linoleic Acid (23.92%) followed by palmitic acid (22.18%), oleic acid (20.40%) and Lauric Acid (8.34%). The composition of the Zingiber officinale essential oil and fatty acid has shown that the plant contains true essential oils, implying that the medicinal and flavouring strength of the plants may be attributed to its essential oil composition.

“…The crude protein(CP) of the PFAs was highest at ginger, with the CP content of 7.23%. However, this value was lower than 8.83% CP reported by Ugwoke and Nzekwe (2010) when chemical analysis of ginger was carried out but higher than 5.28% CP reported by Adanlawo and Dairo (2007).Also, the values in this experiment supersedes 1.83% CP reported by Ahaotu and Lawal (2019) during the determination of proximate composition of turmeric. However, the ash and fibre contents in this study were highest at Turmeric + Garlic which showed that the mixture of these PFAs had higher mineral compositions for optimal performance of the birds.…”

Performance and egg qualities of old-laying hens fed with diets containing ginger, turmeric and garlic were evaluated in a twelve (12) week feeding trial. A total of 135 laying birds of Isa-Brown strain which were sixty-four (64) weeks old were used for the trial and arranged in a completely randomized design. Five diets were formulated for the trial: Diet 1 (control), Diet 2 (3% inclusion level of turmeric), Diet 3 (3% inclusion level of ginger), Diet 4 (turmeric and garlic at 2.25% and 0.75%, respectively) and Diet 5 (ginger and garlic at 2.25% and 0.75%, respectively). Proximate compositions of the Phytogenic Feed Additives (PFAs) were determined with the moisture content ranging between 5.03-7.50%; ash (3.26-6.11%); ether extract (7.39-14.58%); fibre (10.28-13.79%); protein (3.07-7.23%) and Nitrogen Free Extract (58.88-61.54%). The performance indices, though not significantly (P˃0.05) influenced by the test diets except for Hen Day Production (HDP) had the highest weight gained (0.16kg) recorded for birds fed on a diet containing ginger. The highest (62.92 and 62.04 %) HDP were observed in birds fed diets containing ginger and ginger + garlic; respectively. However, the lowest weight gained (0.04kg) was recorded in birds fed a diet containing turmeric + garlic; this diet also recorded the lowest % HDP and FCR with values of 57.50% and 2.37 respectively. The overall values for the qualities of eggs from laying hens fed the PFAs showed that only the Haugh Unit, yolk colour and albumen height were significantly (P˂0.05) affected; with those on Turmeric + Garlic diets having the highest for these parameters. However, the fatty acid variables were not significantly (P˃0.05) affected by the dietary treatments. It could be concluded that the inclusion of PFAs in the diets of laying hens especially at an older age would help to sustain performance with improved quality.

“…More than 400 compounds have been found in the chemical analyses of ginger [21]. These compounds includes alkaloids; saponins; flavonoids; steroids; tannins; carbohydrates; glycosides; proteins; amino acids; dietary fiber; ash; phytosterols; vitamins A, B, and C; minerals; and terpenoids [22][23][24] while detected to be devoid of acid compounds and reducing sugars [23].…”

Ginger Cultivation and Its Antimicrobial and Pharmacological Potentials

Zingiber officinale, belonging to the family Zingiberaceae, is a popular spice and herb used as delicacy and to manage numerous diseases such as diabetes, hypertension, cancer, ulcer, diarrhea, cold, cough, spasm, vomiting, etc. in folk medicine from China, India, and Arabia Peninsula to other continents of the world including Africa (Nigeria, Egypt, and so on). Though this review is aimed at summarizing the pharmacological potentials of this well-endowed spice, interestingly, we found out that these reported ethnobotanical uses are attributed to a number of inherent chemical constituents including gingerol, 6-, 8-, 10-gingerol, 6-shogaol, 6-hydroshogaol, oleoresin, etc., eliciting various pharmacological effects, not limited to antioxidant, antitumor/anticancer, anti-inflammatory, antihyperglycemic, antihypertensive, anticholesterolemic, antibiotic/antimicrobial, neuroprotective, antiulcer/gastroprotective, antiemetic, hepatoprotective, and antiplatelet aggregation, safety profiles established through a number of studies (in vitro, in vivo, and cell lines), though some of these potentials are yet to be explored. Sadly, even few of these established effects are yet to be experimented in clinical trials, and only until these are intensified would there be prospect toward drug development for preventive and curative treatments. In conclusion, we are able to highlight and sum up the therapeutic implications of ginger and its related derivatives in the management of ailments confronting humanity.
