We have investigated the neuroprotective and memory enhancing effect of [6]-gingerol (GIN), a pungent ingredient of ginger, using an animal model of amnesia. To determine the neuroprotective effect of GIN on cognitive dysfunction, scopolamine (SCO, 1 mg/kg, i.p.) was injected into C57BL/6 mice, and a series of behavioral tests were conducted. SCO-induced behavior changes and memory impairments, such as decreased alteration (%) in Y-maze test, increased mean escape latency in water maze test, diminished step-through latency in passive avoidance test, and shortened freezing time in fear condition test, were significantly prevented and restored by the oral administration of GIN (10 or 25 mg/kg/day)...

This study aims to investigate the effect of oral administration and the direct action of ginger extract or [6]-gingerol on small intestinal contractility. The direct effect of 10 minutes preincubation of ginger ethanolic extract (10, 100 and 300 μg/mL) or [6]-gingerol (1, 30, and 100 μM) on 0.01 to 30 μM ACh-induced contractions of all parts of the small intestine isolated from normal rats was investigated using the organ bath technique. For in vivo study, the rats were orally administered with extract (10, 20, and 100 mg/kg/d) or [6]-gingerol (2 mg/kg/d) for 7 days, followed by determining the contractile responses to ACh of rat isolated duodenum, jejunum, and ileum and their histology were assessed...

6-Gingerol (6-G) is known to alleviate myocardial ischemia/reperfusion injury. However, the underlying molecular mechanisms of 6-G myocardial protection are not known. In this study, the protective effect of 6-G on ischemia/reperfusion (I/R) damage and whether such a mechanism was related to apoptosis inhibition and activation of phosphoinositide 3-kinases (PI3K)/serine/threonine kinase (Akt) signaling pathway were investigated. Rats were subjected to I/R in the presence or absence of 6-G and the changes of cardiac function, infarct size and histopathological changes, and the levels of cardiac troponin T, creatine kinase-MB, and myocardial apoptosis were examined...

ETHNOPHARMACOLOGICAL RELEVANCE: Yijin-Tang (YJT) is a traditional prescription for the treatment of hyperlipidaemia, atherosclerosis and other ailments related to dampness phlegm, a typical pathological symptom of abnormal body fluid metabolism in Traditional Korean Medicine. However, a holistic network pharmacology approach to understanding the therapeutic mechanisms underlying hyperlipidaemia and atherosclerosis has not been pursued. AIM OF THE STUDY: To examine the network pharmacological potential effects of YJT on hyperlipidaemia and atherosclerosis, we analysed components, performed target prediction and network analysis, and investigated interacting pathways using a network pharmacology approach...

Ginger is a commonly used spice around the world. Its bioactive compounds contain hydrophobic gingerols and hydrophilic polysaccharides. Huge physiochemical differences between these compounds and the thermal instability of gingerols impede fast and effective extraction of them using conventional methods. In this research, ionic liquid-based ultrasonic-assisted extraction (ILUAE) was applied to simultaneously extract gingerols and polysaccharides from ginger. Parameters influencing the recovery of gingerols were ionic liquid type, ionic liquid concentration, solid/liquid ratio, ultrasonic power, extraction temperature and extraction time...

Chronic mild stress (CMS) has been demonstrated to contribute to atherosclerosis. 6-gingerol (6-Gin), a phenolic component of ginger (Zingiber officinale), has been shown to exert numerous pharmacological properties, such as anti-inflammatory and cardioprotective effects. Here we investigated the role of CMS in the development of atherosclerosis in high-fat diet (HFD)-fed ApoE-/- mice and evaluated the potential therapeutic effects of 6-Gin. Mice were exposed to CMS for 20 weeks, at week 5, they were fed with a high-fat diet (HFD), then received 6-Gin (20 mg/kg/day, intragastrically) treatment...

Ginger juice, a commonly used adjuvant for Chinese materia medica, is applied in processing of multiple Chinese herbal decoction pieces. Because of the raw materials and preparation process of ginger juice, it is difficult to be preserved for a long time, and the dosage of ginger juice in the processing can not be determined base on its content of main compositions. Ginger juice from different sources is hard to achieve consistent effect during the processing of traditional Chinese herbal decoction pieces...

RATIONALE: Xiao Chai Hu Tang (XCHT, Sho-saiko-to in Japanese) is a well-known medicine formula used in Asia for centuries. However, the quality control and the absorption of XCHT components are the major remaining concerns.. The study was to develop a sensitive and robust method to characterize the chemical components in XCHT and evaluate their absorptions. METHODS: An ultra-high pressure liquid chromatography coupled with electrospray ionization quadrupole time-of-flight mass spectrometry (UHPLC-ESI-QTOF MS/MS) was used to identify the compounds in XCHT...

Cancer is the second leading cause of death with profound socio-economic consequences worldwide. Growing evidence suggests the crucial role of diet on cancer prevention and treatment. In Traditional Persian Medicine (TPM) there is a major focus on contribution of special diet and foods to cancer management. In the present article, the cytotoxic and antitumor activities of several food items including plants and animal products recommended by TPM as anticancer agents are discussed. Strong evidence supports the anticancer effects of beetroot (Beta vulgris) and its major compound betanin, cinnamon and cinnamaldehyde, barley (H...

BACKGROUND: Grains of paradise (GP) is the seed of Aframomum melegueta, which is widely distributed throughout West Africa and has been used as a spice and a folk remedy for a long time. Anti-obesity effect of GP intake was demonstrated in a previous report. Aim of the present study was to isolate some compounds in GP and clarify the anti-obesity mechanism. RESULTS: Ten vanilloid compounds were isolated. Among them, 1-(4'-hydroxy-3'-methoxyphenyl)-decan-3-ol and 1-(4'-hydroxy-3'-methoxyphenyl)-3-octen-5-one were determined as novel compounds and 6-gingerol, 6-paradol and 6-shogaol were identified as the major constituents in GP extract...

A practical and highly enantioselective nonenzymatic kinetic resolution of racemic β-hydroxy carbonyl (aldol) compounds through enantioselective dehydration process was developed using a cation-binding Song's oligoethylene glycol (oligoEG) catalyst with potassium fluoride (KF) as base. A wide range of racemic aldols was resolved with extremely high selectivity factors ( s = up to 2393) under mild reaction conditions. This protocol is easily scalable. It provides an alternative approach for the syntheses of diverse biologically and pharmaceutically relevant chiral aldols in enantiomerically pure form...

Gingerols, the pungent ingredients in ginger, are reported to possess a cholesterol-lowering activity. However, the underlying mechanism remains unclear. The present study was to investigate how 6-gingerol (6-GN), the most abundant gingerol in fresh ginger, regulates hepatic cholesterol metabolism. HepG2 cells were incubated with various concentrations of 6-GN ranging from 50 to 200 μM for 24 h. Results showed that both cellular total cholesterol and free cholesterol decreased in a dose-dependent manner. Besides, 6-GN ranging from 100 to 200 μM increased the LDLR protein and uptake of fluorescent-labeled LDL...

Ionizing radiation (IR) is the main modality for locoregional control of unresectable gastric cancer (GC). [6]-Gingerol is an active major phenolic compound isolated from ginger (Zingiber officinale Roscoe), and it has been demonstrated to possess antitumor activity in previous studies. In the present study, we aimed to evaluate the potential activity of [6]-gingerol as a radiosensitizer and to further explore the underlying mechanism. A CCK-8 assay revealed that [6]-gingerol inhibited the cell viability of HGC-27 cells in a dose-dependent manner (P<0...

Endogenous noninfectious substances that mediate the nucleotide oligomerization domain (NOD)-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome activation and interleukin (IL)-1β secretion causes inappropriate sterile inflammation and is implicated in the pathogenesis of several chronic diseases, such as type 2 diabetes mellitus, gout, atherosclerosis and Alzheimer's disease. Consequently, dietary phytochemicals exhibiting capacities to suppress canonical NLRP3 inflammasome-mediated IL-1β secretion can be a reliable supplement to prevent such diseases...
