Abstract:
This study was aimed to observe effect of pomegranate leaf tannin and ellagic acid on primary rat adipocyte differentiation and lipid metabolism-related factor expression. Primary rat preadipocyte was in vitro cultured to observe the effect of pomegranate leaf tannin and ellagic acid on lipid fat cells as well as mRNA expression of its related factor. The results showed that pomegranate leaf tannin and ellagic acid had obvious inhibition effect on fat formation in fat cells. It had certain inhibition effect on activities of lipoprotein lipase (LPL) and glucose-3-phosphate dehydrogenase (GPDH). It promoted fat decomposition and reduced intracellular lipid content. It upregulated PPARγ and fatty acid-binding protein (aP2). It downregulated obese (ob) gene level. It was concluded that pomegranate leaf tannin can inhibit fat generation of fat cells and promote fat metabolism. Ellagic acid was its main active ingredient, which had the same effect as pomegranate leaf tannin.
