Obesity can be defined as a disorder of lipid metabolism and the control of this process is regulated by enzymes involved in lipid metabolic pathway. Obesity is also characterized increases in the number and size of adipocyte differentiated from fibroblastic pre-adipocytes in adipose tissue. The aim of this study was to screen ethanol extracts of 21 fruits and vegetables cultivated in Republic of Korea for identifying natural sources of lipase inhibitor and to investigate the effects of several extracts resulting in suppression of triglyceride (TG) accumulation in 3T3-L1 cells. Among the tested extracts, Diospyros kaki L. showed the highest contents of total sugar and the content of total phenolic compounds was detected 17 species while there was not detected in Ixeris dentate root and Allium fistulosum C. etc. We were screened 26 extracts of fruits and vegetables for pancreatic lipase inhibitory activity compared with orlistat. The strongest lipase inhibitory activities were shown by extract of Allium sativum L. stem, Allium sativum L. bulb, Apteryx australis, Diospyros kaki L. Malus Pumila, Perilla frutescens and Prunus mume regardless of concentrations treated. Eight extracts including Brassica juncea var. integrilolia had no effect on lipase inhibition. During the differentiation of 3T3-L1 preadipocyte to mature adipocyte, the cells were treated with carrier or 7 extracts(1, 5 and 10 ㎍/ml), which was shown to highest lipase inhibitory effects. We were quantified lipid contents secreted mature adipocytes and stained with Oil Red O. All cells treated with the Apteryx australis and Prunus mume significantly decreased TG contents than the control. These findings suggested that the screened fruit and vegetable could be a promising source as the effective and safe lipase inhibitors for isolating bioactive ingredients and developing functional foods.
