Active ingredients from highland barley have received considerable attention as natural products for developing treatments and dietary supplements against obesity.In practical application,the research of food combinations is more significant than a specific food component.This study investigated the lipid-lowering effect of highland barley polyphenols via lipase assay in vitro and HepG2 cells induced by oleic acid(OA).Five indexes,triglyceride(TG),total cholesterol(T-CHO),low density lipoprotein-cholesterol(LDL-C),aspartate aminotransferase(AST),and alanine aminotransferase(ALT),were used to evaluate the lipid-lowering effect of highland barley extract.We also preliminary studied the lipid-lowering mechanism by Real-time fluorescent quantitative polymerase chain reaction(qPCR).The results indicated that highland barley extract contains many components with lipid-lowering effects,such as hyperoside and scoparone.In vitro,the lipase assay showed an 18.4％lipase inhibition rate when the additive contents of highland barley extract were 100 μg/mL.The intracellular lipid-lowering effect of highland barley extract was examined using 0.25 mmol/L OA-induced HepG2 cells.The results showed that intracellular TG,LDL-C,and T-CHO content decreased by 34.4％,51.2％,and 18.4％,respectively.ALT and AST decreased by 51.6％and 20.7％compared with the untreated hyperlipidemic HepG2 cells.qPCR results showed that highland barley polyphenols could up-regulation the expression of lipid metabolism-related genes such as PPARγ and Fabp4.
