Abstract

The invention relates to a method for biosynthesis of magnolol. The method adopts 4-allylphenol as the raw material, and uses laccase as the catalyst for catalysis to complete preparation. The differences between the method and the prior art lie in that: 1) a low-cost compound is taken as the raw material, and the raw material cost of the process is low; 2) on the basis of enzyme reaction, the reaction speed is quick, the selectivity and specificity are good, and the reaction conditions are mild; 3) the process has smaller scale and number of production equipment than other methods, is simplein operation, and is easy for industrial transformation; 4) the method only has separation and purification process in the final step of production, the product purification process is simple, and theproduct has better purity and higher content than general methods; and 5) the synthetic process has no waste liquid emission, is environment-friendly and pollution-free, and can achieve sustainable production. The process adopted by the invention is an excellent industrial production route from the perspectives of economy, environment and occupational health.

Description

technical field [0001] The present invention relates to a kind of biosynthesis method of magnolol, specifically a kind of method of enzymatic catalysis production magnolol. Background technique [0002] Molecular formula of magnolol: C 18 h 18 o 2 ; English name: Magnolol; CAS: 528-43-8; Molecular weight: 266.33; Brown to white fine powder, fragrant, pungent and slightly bitter taste. [0003] In recent years, with the development of modern medicine, it has been found that magnolol has anti-inflammatory, antibacterial, anti-oxidation, anti-tumor and many other pharmacological effects, and has a wide range of applications, such as cosmetics and toiletries. The price of its products is also inseparable from the demand of the international market. [0004] Traditional magnolol production process is divided into Chinese herbal medicine extraction and organic chemical synthesis. Most of the actual market is based on plant extraction. Organic chemical production steps are c...
