Red ginger (Zingiber officinale var. Rubrum) is among the most widely consumed medicinal herbs in Indonesia. Ginger rhizome contains phenol compounds including gingerol and shogaol. 10-gingerol has been reported to exhibit the greatest anti-inflammatory and anti-oxidant activities compared
Ichthyophthirius multifiliis is a ciliate parasite of freshwater fish with a global distribution and results in severe economic losses in aquaculture. The present study aimed to investigate the efficacy and antiparasitic mechanism of active compounds isolated from Zingiber officinale against I.
The determination of 6-, 8-, 10-gingerol, and 6-shogaol in dried ginger (Zingiber officinale) and in the dried aqueous extract of ginger is reported. This is the first study to report a validated method for the determination of these 4 analytes. Several extraction solvents and methods were examined,
Different extracts (ethanolic, hexane, aqueous) of ginger (rhizomes of Zingiber officinale) and the essential oil were tested using [14C]guanidinium influx into N1E-115 cells and the isolated rat ileum in order to identify their activity in inhibiting 5-HT3 receptor function. The hexane extract
Three unprecedented purine-containing compounds, named [6]-, [8]-, and [10]-zingerines as they are 5-(6-amino-9H-purin-9-yl) analogs of [6]-, [8]-, and [10]-gingerols, respectively, were isolated from a methanolic extract of ginger rhizomes using a phase trafficking-based method that utilizes solid
A rapid and sensitive RP high-performance thin-layer chromatographic (RP-HPTLC) methodology was developed and validated for the quantitative estimation of gingerols in methanolic extract of fresh ginger rhizome. The samples were chromatographed on RP-TLC glass plates pre-coated with RP-18 60F(254)
A novel method for purifying gingerols from ginger was developed using a high-speed counter-current chromatography (HSCCC). The two-phase solvent system such as light petroleum (bp 60-90°C)-ethyl acetate-methanol-water (5:5:6.5:3.5, v/v/v/v) was applied to the separation and purification of 6-, 8-
This study explored the effect of different nonthermal pretreatments, osmosonication (OS), osmotic dehydration, and ultrasound methods on the physical and chemical properties of China- and Ghana-sourced ginger samples under relative humidity convective drying. The chemical properties of pretreated
Despite significant advances and development of novel anti-emetics, nausea and vomiting (emesis) is a major side-effect of cancer chemotherapy. At times, severe nausea and vomiting may also lead to reduction in adherence to the treatment regimen, and this will concomitantly affect the patient's
Extensively drug-resistant Acinetobacter baumannii (XDRAB) is a growing and serious nosocomial infection worldwide, such that developing new agents against it is critical. The antimicrobial activities of the rhizomes from Zingiber officinale, known as ginger, have not been proven in clinical
Five compounds were isolated from the chloroform-soluble fraction of the methanolic extract of the dried rhizomes of Zingiber officinale (Zingiberaceae) through repeated column chromatography. Their chemical structures were elucidated as 4-, 6-, 8-, and 10-gingerols, and 6-shogaol using
Magnolol and honokiol, biphenyl compounds, were isolated as anti-emetic principles from the methanolic extract of Magnolia obovata bark. [6]-, [8]-, and [10]-shogaols and [6]-, [8]-, and [10]-gingerols were isolated from the methanolic extract of Zingiber officinale rhizome as anti-emetic
In this study, we investigated the anthelmintic activity of [6]-gingerol, [10]-shogaol, [10]-gingerol, [6]-shogaol and hexahydrocurcumin, a constituent isolate from the roots of ginger (Zingiber officinale), for the parasite Angiostrongylus cantonensis. This study found that the above constituents
Ginger (Zingiber officinale R.) is a popular spice used worldwide. The oleoresin consists of gingerols, shogaols and other non-volatiles as chief bioactive constituents. Three phase partitioning (TPP), a bioseparation technique, based on partitioning of polar constituents, proteins, and hydrophobic
OBJECTIVE
To discuss the synergistic mechanism of compatible use of two medicinal herbs, Zingiber offiicinale and Aconitum cainichaeli, by determining single decoction of Z. offiicinale and four gingerols (6-gingerol, 8-gingerol, 6-shogaol, 10-gingerol) contained in compound decoction of Z.
