8 gingerol/ショウガ属

OBJECTIVE To develop and validate a simple, accurate HPTLC method for the analysis of 8-gingerol and to determine the quantity of 8-gingerol in Zingiber officinale extract and ginger-containing dietary supplements, teas and commercial creams. METHODS The analysis was performed on 10×20 cm

To evaluate vasorelaxant and vasoconstriction effects of Zingiber officinale var. rubrum (ZOVR) on live rats and isolated aortic rings of spontaneously hypertensive rats (SHRs).

Extracts of ZOVR were subjected to in-vivo antihypertensive

In this study we investigate the active constituents of the rhizome of Zingiber officinale, Roscoe (ginger) and determine their activity on glucose uptake in cultured L6 myotubes and the molecular mechanism underlying this action. Freeze-dried ginger powder was extracted with ethyl acetate (1 kg/3

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

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-

The effects of different drying methods (freeze drying, vacuum oven drying, and shade drying) on the phytochemical constituents associated with the antioxidant activities of Z. officinale var. rubrum Theilade were evaluated to determine the optimal drying process for these rhizomes. Total flavonoid

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

A new phenylpropanoid ester mixture, (E)-geranylferulic acid (1a) and (Z)-geranylferulic acid (1b), along with 13 known compounds, [6]-gingerol (2), [8]-gingerol (3), [10]-gingerdione (4), 1-dehydro-[6]-gingerdione (5), 1-dehydro-[8]-gingerdione (6), [6]-paradol (7), [8]-paradol (8),

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.

The rhizome of the Zingiber officinale Roscoe, a biennial herb growing in South Asia, is commonly known as ginger. Ginger is used in clinical disorders, such as constipation, dyspepsia, diarrhoea, nausea and vomiting and its use is also recommended by the traditional medicine for cardiopathy, high

BACKGROUND Ginger (Zingiber officinale Roscoe) is a well known anti-inflammatory drug in the Egyptian, Indian and Chinese folk medicines, yet its mechanism of action is unclear. OBJECTIVE To explore its mechanism of action and to correlate it to its biophytochemicals. METHODS Various extracts viz.

Gingerols and shogaols are recognized as active ingredients in ginger and exhibit diverse pharmacological activities. The preclinical pharmacokinetics and tissue distribution investigations of gingerols and shogaols in rats remain less explored, especially for the simultaneous analysis of

Zingiber species are members of the Zingiberaceae family, and are widely used for medicinal and food purposes. In this study aboveground and root parts of Zingiber mioga and Zingiber officinale were subjected to metabolite profiling by ultra-performance liquid
