“…In recent years, the isolation of the chiral drugs has received prominent attention [1,2]. HPLC based on chiral stationary phases (CSPs) has become one of the most attractive approaches to chiral separations due to its simplicity, speed and selectivity [3][4][5]. Due to the high column efficiency and column capacity, the Brush-type CSPs has been widely used in the field of medicine [6,7].…”
