Rapid recovery of high content phytosterols from corn silk
BACKGROUND Phytosterols have important physiological and officinal function. METHODS An efficient ultrasonic assisted extraction, purification and crystallization procedure of phytosterols was established from corn silk for the first time. RESULTS The orthogonal test was applied to optimize the process parameters and a maximum phytosterols recovery as high as 10.5886 mg/g was achieved by ul...
