Study on Purifying Process of Salidroside by Resin

Abstract

Abstract: With alcohol extracting solution of Rhodiola sachalinensis powder processed by supercritical CO2 extraction, the purification process of salidroside was studied with resin. The optimal process conditions were: the kind of resin NKA-Ⅱ, the consumption of resin 5mg(salidroside)/g(dry resin), the strippant ratio of methylene dichloride to ethanol 7:3, the flow rate of strippant 2 times volume of column/h and the consumption of strippant 16ml/g(dry resin). The purity of salidroside can reach 40% by this purification process. The ratio of stripping is 98.02%.

Key words: salidroside, resin, purification
