MATERIALS AND METHODS
Geuk Fruits Collection and Preparation
Geuk fruits were harvested in Agricultural Research Center for Climate Change (National Institute of Horticultural and Herbal Science, Rural Development Administraion, Jeju, Korea) in February, 2011 and were transported to the laboratory within 24 h. Among the fully ripe fruits, three fruits were selected to be used in this experiment, which were randomly selected. All fruits were separated two parts (Fig. 1, pulp and seed aril) and then lyophilized. All dry geuk fruits were ground into powder and stored at -20˚C until analysis.
