Research progress of alternative production approaches of salidroside

Salidroside, one of the active components of Rhodiola plants, is a phenolic glycoside with significant biological activities. The investigation and development of alternative production approaches of salidroside is of high academic and application values due to the limited resource of Rhodiola plants, and from which the low yield of salidroside. This review summarized the research progress and perspective of the alternative production approaches of salidroside including both chemosynthetic and biosynthetic methods and pathways.
