Investigating the inhibitory activity of green coffee and cacao bean extracts on pancreatic lipase
2010
The present study investigated the effects of green coffee bean extract and Theobroma cacao bean extract on pancreatic lipase activity in vitro. Green coffee bean extract produced a J-shaped dose-dependent inhibition of pancreatic lipase with the percentage inhibition of pancreatic lipase ranging from 11.8% to 61.5%. Similar concentrations of Theobroma cacao failed to produce any effect on pancreatic lipase. Non-linear regression analysis revealed that the concentration of green coffee bean extract required to elicit a 50% inhibition of pancreatic lipase activity (IC50) was approximately 43 μM. In conclusion, extracts of green coffee beans but not Theobroma cacao possess potent inhibitory activity against pancreatic lipase.
