Banana (Musa acuminate Colla) is widely grown in tropical regions. Banana peel is normally discarded and thrown away as waste. Although several studies have reported the nutritional value of bananas, the biological activities of banana peel are relatively unknown. In this study, we investigated the anti-adipogenic activities of water and ethanol extracts of banana peel (BPE-W and BPE-E, respectively) and banana peel matured for 2 days at room temperature (MBPE-W and MBPE-E, respectively) on 3T3-L1 adipocytes. To evaluate the effects of the extracts on 3T3-L1 adipogenesis, the cells were treated with 10 and 100 μg/mL of the extracts from day 2 to day 6. Treatment with 100 μg/mL of extracts significantly inhibited lipid accumulation in 3T3-L1 adipocytes. The BPE-W and BPE-E showed strong anti-adipogenic activities compared to MBPE-W and MBPE-E. Furthermore, 3T3-L1 adipocytes treated with the extracts down-regulated the transcription factor CCAAT/enhancer binding protein beta (c/EBPβ) and peroxisome proliferator-activated receptor gamma (PPAR-γ) expressions. Taken together, our results indicate that the hydrolysis of components such as tannins in banana peel during maturation could affect the anti-adipogenic activities of banana peel extracts. The results of the study suggest a potential role for banana peel extracts as ingredients in the development of functional foods for obesity.
