Abstract Title:
Anti-obesity effects of enzyme-treated celery extract in mice fed with high-fat diet.
Abstract:
The present study demonstrated the anti-obesity effects of enzyme-treated celery extract (ECE) in mice on high-fat diet (HFD). In vitro studies showed that ECE has anti-adipogenic properties by inhibiting lipid accumulations in adipose cells. In vivo studies indicated that the administration of ECE markedly prevented HFD-induced body weight gain, food efficiency ratio, and epididymal fat and liver weights. ECE reduced lipid parameters, cardiac risk factor, and atherogenic index in obese mice. ECE prevented a diabetes state by improving adipokines levels, reducing glucose levels, and preventing insulin resistance. Moreover, ECE prevented HFD-induced liver damage by preventing hepatic steatosis and upregulation of liver antioxidant enzymes. The mechanism of ECE was partially investigated to involve the activation of 5' adenosine monophosphate-activated protein kinase and hence the downregulation of CCAAT/enhancer binding proteinα and peroxisome proliferator-activated receptor γ by ECE. Our results suggest that ECE could be used as functional food materials for the prevention of obesity. PRACTICAL APPLICATIONS: Apium graveolens is a popular plant with nutritive and medicinal benefits. It contains bioactive compounds suchas apiin, apigenin, and luteolin. However, these compounds are rendered insoluble due to their interaction with polysaccharides in the cell wall thus making them less bioavailable. Hydrolyzing them could increase the yield of bioactive compounds in celery. This pilot study demonstrates that pectinase-treated celery extract has anti-obesity effects. The results of this research demonstrate the use of enzymes in improving the biological activities of plant extracts and suggest the use of enzyme-assisted extraction techniques in the industrial production of health functional food from celery.
