Effects of pectin lyase-modified red ginseng extracts in high-fat diet-fed obese mice

چکیده
Red ginseng and its extracts have been used as traditional medicines and functional foods in countries worldwide. The aim of this study was to examine the bioavailability of pectin lyase-modified red ginseng extracts (GS-E3D), and the effects of GS-E3D on adipogenesis of 3T3-L1 adipocytes, as well as on metabolic disorders such as hyperglycemia, dyslipidemia, and fatty liver in high-fat diet fed obese C57BL/6 mice. Mice were divided into 5 groups: normal diet group, high fat diet-vehicle group, high fat diet + 0.1 g/kg GS-E3D (0.1-GS-E3D), high fat diet + 0.3 g/kg (0.3-GS-E3D), high fat diet + 1.0 g/kg (1.0-GS-E3D). Treatment of GS-E3D reduced differentiation of 3T3-L1 adipocytes with low cytotoxicity. In the animal model, compared to the high fat diet control, serum glucose, total cholesterol, LDL-cholesterol, HDL-cholesterol, TG, and leptin level were reduced in treatment animals in a dose-dependent manner. In addition, we found that GS-E3D could decrease total hepatic lipid droplets. These results suggest that GS-E3D, as a dietary supplement, has beneficial effects on obesity and may have useful effects in health-care products.

Black ginseng is produced by a repeated steaming process. The aim of this study was to investigate the anti-obesity effects of black ginseng ethanol extract (BG-EE) in high fat (HF) diet-fed mice. Two groups were fed either a normal control (NC) diet or a HF diet (45% kcal fat). The other three groups were given a HF diet supplemented with 1% BG-EE, 3% BG-EE, and 5% BG-EE for 12 wk. The anti-ob...

Obesity and diabetes are growing health problems worldwide. In this study, dietary provision of Chinese ginseng (0.5 g/kg diet) prevented body weight gain in high-fat (HF) diet-fed mice. Dietary ginseng supplementation reduced body fat mass gain, improved glucose tolerance and whole body insulin sensitivity, and prevented hypertension in HF diet-induced obese mice. Ginseng consumption led to re...
