Short-Term Effects of PJE Administration on Metabolic Parameters in Diet-Induced Obesity Mice

The study investigated the effects of Petasites japonicus (Siebold & Zucc.) Maxim. extract (PJE) and fenofibrate on diet-induced obesity (DIO) in mice. PJE was found to contain various bio-active polyphenolic compounds, including kaempferol, p-hydroxybenzoic acid, ferulic acid, gallic acid, chlorogenic acid, 3,4-dicaffeoylquinic acid, caffeic acid, quercetin, rutin, protocatechuic acid, 3,5-dicaffeoylquinic acid, 4,5-dicaffeoylquinic acid, p-coumaric acid, apigenin, and 1,3-dicaffeoylquinic acid. The results showed that PJE treatment up to 1000 mu g/mL did not affect the viability of 3T3-L1 cell line, and it reduced the feed efficiency ratio in DIO mice. PJE administration also resulted in a significant reduction in body weight gain and fat accumulation in the liver compared to the DIO control group. Additionally, PJE administration improved the levels of lipid and related parameters, including total cholesterol, triacylglycerol, low-density lipoprotein, very low-density lipoprotein, glucose, insulin, insulin resistance, leptin, and atherogenic or cardiac indexes compared to the DIO control group. The study suggested that PJE may have a beneficial effect on insulin resistance, lipid profiles, atherogenesis, adipokines, and cardiac risk associated with diet-induced obesity.

Automated summary

This study investigated the effects of Petasites japonicus (Siebold & Zucc.) Maxim. extract (PJE) and fenofibrate on diet-induced obesity (DIO) in mice. The results showed that PJE treatment reduced feed efficiency ratio, body weight gain, and fat accumulation in the liver compared to the control group. Additionally, PJE administration improved lipid profiles, insulin resistance, and cardiac risk factors associated with DIO.
