A-salidroside, method for preparing same, and application thereof

Abstract

An α-salidroside, a method for preparing same, and application thereof. A novel type of salidroside, namely, α-salidroside, which when compared with the known β-salidroside, α-salidroside exhibits superior activity in scavenging DPPH radicals and hydroxyl radicals and can be added as a new functional ingredient to cosmetics or anti-fatigue health supplements. The method for preparing α-salidroside involves using inexpensive starch, etc., as a glycosyl donor and tyrosol as a substrate, synthesizing α-salidroside under the action of glycosyltransferase. The glycosyltransferase has strict specificity and chiral catalytic ability, enabling the specific generation of α-salidroside.
