Continuous or Batch Solid-Liquid Extraction of Antioxidant Compounds from Seeds of Plant and Kinetic Release Study.

This work has been intended to investigate the antioxidant properties of compounds extracted from seeds of (a plant from Central America) in order to add further results to the relatively poor existing literature on the beneficial properties of this plant. Different extraction methodologies were used such as batch or continuous extraction conditions using water or ethanol 50% as solvents. The kinetic study has allowed estimation of the effective diffusion coefficients in a continuous solid-liquid extraction, highlighting the strict dependence of the diffusion rate and temperature and kind of solvent, showing the highest diffusion rate with ethanol 50% at 60 °C.
