Implementation of the Acclimatization Process for Ginger Plantlets (Zingiber officinale Roscoe)

Ginger (Zingiber officinale Roscoe) is an important culinary and medicinal spice but is rarely cultivated due to the unavailability of seeds. Given the difficulties in adapting to plantlets produced in natural environments, it is important to analyze the survival conditions of ginger plantlets. For this reason, we varied the incubation temperature and humidity as well as the substrate during the weaning phase. Then, we varied the nutrients contained in the watering solution during the hardening phase. The statistical analysis showed that physical factors and substrates significantly influenced (p < 0.0001) plantlet survival. Nutrient solutions significantly influenced the phylogenesis, rhizogenesis, and height growth of the plantlets. The suitable physical factors for good development of plantlets are a temperature of 26.54˚C and a humidity of 96.16%. The 1C2T2TC substrate (1 Compost + 2 Soil + 2 Coconut Peat) had a significant survival rate of approximately 92.5%. During hardening, the Plantzym solution promoted good growth in terms of plantlet height (0.6 cm) and good development of roots (30 roots) and leaves (03 leaves). This work will make it possible to develop a technical seed production sheet for better development of ginger cultivation in Benin.

<i>Streptomyces zerumbet</i>, a Novel Species from <i>Zingiber zerumbet</i>(L.) Smith and Isolation of Its Bioactive Compounds

Streptomyces zerumbet W14, a novel species of the endophyte genus Streptomyces was isolated from the rhizome tissue of Zingiber zerumbet (L.) Smith. Identification of strain W14 was based on its morphology, chemotaxonomy and phylogenetic analysis using 16S rDNA sequence. It was classified as the secondary meabolites of the culture extract were studied. The major active ingredients from the crude extract were purified by silica gel column chromatography and identified by spectroscopic data. The crude extract and purified compounds were tested for their biological activities on antibacterial and anti-inflammatory properties. The crude extract showed inhibition on the growth of Gram-positive bacteria with the MIC and MBC values of 8 - 32 μg/ml and 32 - 128 μg/ml, respectively. The isolated compounds were identified to be methyl 5-(hydroxymethyl)furan-2-carboxylate (1) and geldanamycin (2). Bioassay studies showed that compound 1 had antibacterial activity against Staphylococus aureus ATCC 25923 and Methicillin Resistant S. aureus strain Sp6 (clinical isolate) with the MIC and MBC values of 1 μg/ml and 16 - 64 μg/ml, respectively, and also showed activity against Bacillus Calmette-Guérin (vaccine strain) with MIC and MBC values of 128.00 μg/ml and 128.00 μg/ml, respectively. The compound 2 at the concentration of 1 - 5 μg/ml had in vitro anti-inflammatory activity on LPS-induced RAW 264.7 cells by inhibition of mRNA expression and production of inducible NO synthase (iNOS), tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6). These results suggest that compounds 1 and 2 produced by S. zerumbet W14 (an endophyte of Z. Zerumbet) have antibacterial and anti-inflammatory activities, respectively. Therefore, the future studies on these compounds could be useful for the management of bacterial infections and inflammatory diseases.

Antimicrobial Activity of Essential Oil of <i>Zingiber officinale</i>Roscoe (Zingiberaceae)

Zingiber officinale, commonly known as ginger, is a species native of tropical Asia. It is grown and used in tropical countries of America, including Mexico, where it is used for the treatment of throat infections. The aim of this study was to determine the chemical composition of essential oil of Z. officinale rhizome and evaluate their antimicrobial activity. The essential oil was obtained by hydrodistillation, and the chemical composition of the oil was determined by GC-MS. To determine the antimicrobial activity diffusion, agar dilution and radial growth inhibition methods were employed. Microbial growth curves were performed on the strains most susceptible. It was identified 28 compounds in the essential oil, the most abundant were eudesmol (8.19%), γ-terpinene (7.88 %), a-curcumene (7.28%), alloaromadendrene (6.56%), zingiberene (6.06 %), α-pinene (5.76 %), δ-cadinene (3.84%), elemol (3.39%), farnesal (3.45%), E-β-farnesene (3.57%), neril acetate (2.8%) and β-myrcene (2.94%). In antimicrobial activity, the essential oil inhibited the growth of 15 bacterial strains, 3 of yeast fungi and 4 of mycelia fungi. The most susceptible strains were S. aureus FES-I (MIC = 0.25 mg/mL) S. epidemidis FES-C (MIC = 0.5 mg/mL), E. faecalis ATCC 14506 (MIC = 1.0 mg/mL), C. tropicalis (CMI = 0.125 mg/mL) and T. mentagrophytes (CF50 = 0.08 mg/mL). In the microbial growth curves the essential oil showed bactericidal effect on S. aureus FES-I and S. marcescens ATCC 14756 from the first hour of exposure of the strains to oil, eliminating 99.9% of CFU in concentrations of 0.5 and 0.75 mg/mL respectively. The results validate the medicinal use of Z. officinale in the treatment of diseases of possible infectious origin.

Effect of Biofertilizer on Growth, Productivity, Quality and Economics of Rainfed Organic Ginger （Zingiber officinale Rosc.） Bhaisey cv. in North-Eastern Region of India

Ginger yields in the NorthEastern region of India are low because the extremely poor farmers of the region can not afford to apply any chemical fertilizers and hence apply only the locally-available farmyard manures to ginger fields. Biofertilizers may be a cheap source of fertilizers for ginger cultivation as they can increase nutrient availability and improve rhizome quality and are required in small quantity. An investigation was thus undertaken to study the effect of different biofenilizers on growth, productivity, quality and economics of organic ginger grown under rainfed condition in NorthEastern region of India. Seed treatment with biofertilizers enhanced growth, increased rhizome yield by 19.0% and resulted in 32.4% higher net profit over control. Among the seed treatments, Azotobacter 5.0 kg ha＂l, Azospirillum 3.75 kg hal and Phosphotica 3.75 kg ha-1 were found optimum in improving most of the growth attributes, increasing yield components and yield of rhizome by 5.6%-13.5%. They also improved rhizome quality by increasing specific gravity, oleoresin and dry matter content and by decreasing crude fibre in rhizome. They resulted in higher net return by 4.0%-12.0% as compared to their other levels. Combined use of Azotobacter 5.0 kg hal along with Phosphotica 3.75 kg ha＂l was found to be the best treatment combination which greatly improved growth and yield attributes of ginger and ultimately recorded markedly higher productivity （2.0%-23.5%） over other combinations. This treatment combination improved the quality of the produce and resulted in the highest gross return （$4,905 hal）, net return （$3,525 hal） and return per dollar （3.55） invested in ginger cultivation. It appears that growing organic ginger by treating the seed rhizome with Azotobacter 5.0 kg ha-~ along with Phosphotica 3.75 kg ha-1 can result in good growth and high productivity of improved quality rhizome and ultimately result in maximum net profit and thus can be recommended for the NorthEastern region of India.

Evaluation of Various Crude Extracts of <i>Zingiber officinale</i>Rhizome for Potential Antibacterial Activity: A Study <i>in Vitro</i>

In vitro antibacterial activity of crude aqueous and organic extracts of rhizome of Zingiber officinaleRoscoe (ginger) was studied against both Gram-negative (Escherichia coli and Salmonella typhi) and Gram-positive (Bacillus cereus, Bacillus subtilis, Staphylococcus aureus and Streptococcus pyogenes) bacterial strains. The present study reveals that the pattern of inhibition varied with the solvent used for extraction and the organism tested. Plant extracts prepared in organic solvents provided more consistent antibacterial activity as compared to aqueous extracts. Methanol extract was the most active against maximum number of bacterial species tested. Gram-positive bacteria were found the most sensitive as compared to Gram-negative bacteria. Staphylococcus aureus was significantly inhibited by almost all the extracts even in very low MIC followed by other Gram-positives. Escherichia coli (a Gram-negative bacterium) was showing the least inhibition with highest MIC values, while Salmonella typhi was found completely resistant. Methanol extract yielded the presence of terpenoids, flavonoids, alkaloids and tannins in phytochemical screening. Results of the present study sign the interesting assurance of designing a potentially active antibacterial agent from Zingiber officinale.

Effect of Zingiber Officinale Sucus on contraction of isolated duodenum in rabbits

Objective:Observation of ginger (Zingiber Officinale Sucus, ZOS) effect on rabbit isolated duodenum and to explore the correlation mechanism with M and H1 receptor. To investigate the effects of ZOS on isolated duodenum of rabbits treated with acetylcholine, histamine, atropine and chlorpheniramine respectively. Methods: The optimal concentration of ZOS was 1% and the above drugs were applied to the isolated duodenal segments respectively. The contractile force was recorded by BL-420E biological signal acquisition system. Results: The results showed that ZOS significantly inhibited the contraction of isolated rabbit duodenal smooth muscle in a positive concentration-dependent manner. The mechanism of inhibiting contraction had little correlation with M and H1 receptors. Conclusion: It could inhibit the efficacy of acetylcholine and histamine, and was a synergist for atropine and chlorpheniramine. This study provided a basis for the use of ginger in daily life and the development of combined medication.

Effect of Avocado （Persea Americana）, Cabbage （Brassica Oleracea） and Ginger （Zingiber Officinale） on Rat Liver and Thyroid Injuries Induced by CCI4 （Carbon Tetrachloride）

Avocado, Cabbage, and Ginger are a part of a regular human diet and have antioxidant, and antitumor effects. The effect of AVOE （avocado）, GE （Ginger） and CE （Cabbage） extracts separately on liver NO （nitric oxide）, MDA （malondialdehyde）, as well as serum AST （aspartate aminotransferase）, ALT （alanine aminotransferase）, total bilirubin, TC （total cholesterol）, T.G （triglyceride）, HDL cholesterol （high-density lipoprotein）, LDL cholesterol （low-density lipoprotein）, TSH （thyroid-stimulating hormone）, T3 （Triiodothyronine）, T4 （Thyroxine） in rats treated and untreated with CC14 （carbon tetrachloride） was studied. The levels of NO, MDA, as well as serum AST, ALT, total bilirubin, TC, T.G, LDL, and TSH, showed an elevation while, HDL, T3 and T4 showed the decline in rats treated with CC14 as compared to control. Treatment of rats with AVOE and GE pre, during, and post CC14 administration improve NO, MDA, as well as serum AST, ALT, total bilirubin, TC, T.G, HDL, LDL, TSH, T3, T4 as compared to CC14. Treatment of rats with CE pre, during, and post CC14 administration did not improve in the thyroid hormones and lipid profile levels as compared to CC14. These findings suggest that avocado and ginger treatment exerts a protective effect on metabolic disorders by decreasing oxidative stress.

Physicochemical and Microbiological Properties of Bissap (Hibiscus sabdariffa) and Ginger (Zingiber officinale (L) Rose) Juices Sold in the Western Part of Abidjan (Côte d’Ivoire)

Juices made from the calyx of Hibiscus sabdariffa (Malvaceae), commonly called Bissap, and the rhizome of Zingiber officinale (Zingiberaceae), known as Gnamankoudji, are widely consumed in C&ocirc;te d'Ivoire. The artisanal preparation of these juices often makes their quality problematic. The aim of this study is to determine some physicochemical and microbiological properties of these drinks sold in the city of Abidjan. To do this, samples of Bissap and Gnamankoudji juices were collected near schools in the Mamie Adjoua (Yopougon) and Abobodoumé (Attécoubé) districts. Physico-chemical and microbiological analyses were performed on these collected samples. The results show that the Bissap and Gnamankoudji juices have an acid pH (2.47 and 3.71), a low protein content (0.78% and 2.11%) and a high water content (80.13% and 85.21%), respectively. The reducing sugar content ranged from 1.20% to 3.34%, with high total sugar (695 mg/mL and 812 mg/mL), low ash (0.70 ± 0.07;0.91 ± 0.01). On the other hand, these juices contain variable concentrations of minerals from one site to another (magnesium, calcium, phosphorus, potassium and iron). Potassium is the most abundant mineral element, followed by phosphorus and magnesium. Moreover, it is observed that the Gnamankoudji juices contain vitamin C (4.67 to 5.58 mg/100mL), contrary to the Bissap juice. The microbiological analysis indicates the presence of aerobic mesophilic germs (AMG) but a total absence of pathogenic germs in all juices. The important presence of nutrients and the total absence of pathogenic germs in these drinks justify their regular consumption by the population.

Zingiber striolatum Diels （Zingiberaceae） is an edible plant resource in the Chinese folk with special efficacy in relieving diabetes and constipation, which has been documented in the Compendium ofMateria Medica. However, its hypoglycemic activity and constituents have not been reported yet. In the present study, we evaluated the hypoglycemic activity of Z. striolatum in insulin-resistant HepG2 cells, and we developed ultra performance liquid chromatography coupled with tandem mass spectrometry （UPLC-MS/MS） based chemical profiling method for rapid analysis of Z. striolatum. As a result, the ethanol extract from Z. striolatum showed significant hypoglycemic activity in HepG2 cells, and 22 flavonoids compounds were tentatively characterized by comparing the retention time and mass spectrometry data. In conclusion, the method of hypoglycemic screening in insulin-resistant HepG2 cells coupled with UPLC-MS/MS is a feasible and credible technique to separate and identify the active constituents in complex matrices of traditional Chinese medicine.

Anti-fatty liver effects of oils from Zingiber officinale and Curcuma longa on ethanol-induced fatty liver in rats

OBJECTIVE： The present study is aimed at evaluating the protective effects of oils from Zingiber officinale （ginger） and Curcuma Ionga （turmeric） on acute ethanol-induced fatty liver in male Wistar rats. METHODS： Ferric reducing antioxidant power activity and oxygen radical absorbance capacity of the oils were evaluated ex vivo. Rats were pretreated for 28 d with standard drug （Livolin Forte） and oils from Z. officinale and C. Ionga before they were exposed to 45% ethanol （4.8 g/kg） to induce acute fatty liver. Histological changes were observed and the degree of protection was measured by using biochemical parameters such as alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase activities. Serum triglyceride （TG） level, total cholesterol （TC） level and the effects of both oils on reduced gluthatione （GSH）, glutathione-S- transferase （GST）, superoxide dismutase （SOD） and hepatic malondialdehyde （MDA） levels were estimated. RESULTS： Oils from Z. officinale and C. Ionga at a dose of 200 mg/kg showed hepatoprotection by decreasing the activities of serum enzymes, serum TG, serum TC and hepatic MDA, while they significantly restored the level of GSH as well as GST and SOD activities. Histological examination of rats tissues was related to the obtained results. CONCLUSION： From the results it may be concluded that oils from Z. officinale and C. Ionga （200 mg/kg） exhibited hepatoprotective activity in acute ethanol-induced fatty liver and Z. officinale oil was identified to have better effects than C. Ionga oil.
