摘要
A nonthermal process, high hydrostatic pressure (HHP), was used as a new extraction technique to obtain salidroside from Rhodiola sachalinensis. The leaching rates of salidroside were measured under different treatment conditions. When the material was treated under 500 MPa of hydrostatic pressure with 50 times of volume 60% (v/v) of ethanol solution as the extracting solvent, the leaching rate of salidroside was up to 0.401% in 3 min, while that of ultrasonic extraction was at 0.288% in 30 min and that of reflux extraction was at 0.302% in 120 min. The HHP extraction technique showed high efficiency in extracting salidroside at room temperature using moderate ethanol concentration.
