Abstract
Arbutin, a glycosylated compound of hydroquinone, exists in two forms of β-arbutin and α-arbutin based on the configuration of the glycosidic bond. As a safe and stable whitening agent, arbutin is widely used in cosmetics, and it has antioxidant, antimicrobial, anti-inflammatory, and anti-tumor activities. The production of arbutin by plant extraction faces challenges such as long plant growth periods, complex extraction processes, and low yields. The chemical synthesis of arbutin suffers from harsh reaction conditions, poor stereo-selectivity, and low yields. In recent years, biosynthesis emerges as the most popular method to produce arbutin because of the simple and mild reaction conditions, low costs, and environmental friendliness. This review summarizes the research progress in four biosynthetic strategies for arbutin, including plant conversion, enzyme catalysis, whole-cell catalysis, and microbial fermentation. The advantages and limitations of these biosynthetic strategies are discussed, and future research directions are proposed.
