.2.1.1. Maceration method. Briefly, 200 g of the rice bran were macerated with 1 L of 95% ethanol at room temperature for 8 hours.
The extract was filtered through the paper filter. The rice bran
residues were re-extracted by the same process for 3 times. All filtrates
were collected, pooled and dried by a rotary evaporator at 40 ◦C. The dried extracts were kept at −80 ◦C until use.
