Abstract:
A method for preparing extracts from seeds of Vitis Vinifera is provided to reduce the quantity of acetone consumed for extraction by using a mixed solvent of water and acetone while securing a high yield. A method for preparing extracts from seeds of Vitis Vinifera comprises the following steps of: extracting an extract from a mixture of pulverized seeds of the Vitis Vinifera and a acetone/water mixed solvent in a mixing ratio of 1 to 1-2 at a room temperature and filtering the extract; removing the acetone by distilling the obtained extract and saturating the extract with sodium chloride; extracting the saturated extract by ethylacetate and concentrating the extract; and adding chloroform to the concentrated extract to obtain precipitate.
