摘要： This study aimed to investigate the effects of areca flower tea polyphenol extract (AFPE) on the adipogenesis of 3T3-L1 preadipocytes. AFPE was extracted from areca flower tea using boiling water, and the polyphenolic compounds were analysed by HPLC. At doses that they did not induce cytotoxicity, AFPE (50 - 200 mu g/mL) efficiently inhibited triglyceride accumulation in the mature adipocytes in a dose-dependent manner when induced to differentiate. Additionally, AFPE suppressed the secretion of leptin and the expression of lipoprotein lipase (LPL). Moreover, the anti-adipogenic properties were also attributed to the down-regulation of protein expression of major transcriptional factors in adipogenesis, including peroxisome proliferator-activated receptor gamma (PPAR gamma) and CCAT/enhancer-binding protein alpha (C/EBP alpha). Therefore, these results suggest that AFPE may prevent obesity by inhibiting the differentiation of preadipocytes, suggesting its potential application in functional foods and nutraceuticals for obesity management.
