Kaempferia parviflora Ethanol Extract, a Peroxisome Proliferator-Activated Receptor γ Ligand-binding Agonist, Improves Glucose Tolerance and Suppresses Fat Accumulation in Diabetic NSY Mice.

This study assessed the effect of Kaempferia parviflora, also known as black ginger (BG), and its ethanol extract (BGE) on peroxisome proliferator-activated receptor (PPAR) γ agonistic activity, glucose tolerance, fat accumulation, and lipids-induced hypertriglyceridemia in mice. PPARγ ligand-binding capacity in vitro and polymethoxy flavone contents were highly observed in organic solvent extracts. In an animal experiment A, male diabetic Nagoya-Shibata-Yasuda mice were divided into five dietary groups and fed each diet for 8 weeks: AIN-93G diet (low-fat [LF] diet), high-fat (HF) diet, HF diet supplemented with 1% BG, HF diet supplemented with 0.

Camellia japonica Seeds Extract SuppressesLipid-induced Hypertriglyceridemia and Fat Accumulation in Mice.

As the seed extract from Camellia japonica (CJ) contains saponins, inhibitory effects of pancreatic lipase activity and body fat accumulation are expected. To investigate the anti-obesity effect of CJ seed extract, ICR mice were fed with a high-fat diet that was either supplemented or not with 1% CJ seed extract for 53 days. Including CJ seed extract in the high-fat diets of mice increased fecal fat excretion and decreased the body weight gain and lipid parameters in plasma and in the liver.

Effect of green tea extract on reactive oxygen species produced by neutrophils from cancer patients.

Background/aim: Oxidative stress in cancer patients has been demonstrated to be partly mediated by neutrophils. Although it is reported that natural antioxidants, such as green tea extract, reduce oxidative stress, there is limited evidence of their effects in cancer patients. This study aimed to determine the effect of green tea extract on reactive oxygen species produced by neutrophils from cancer patients.
