ABSTRACT
Gastrodin is a major active ingredient in Gastrodia elata, which is one of the traditional rare medicinal herbs in China. It has lots of pharmacological activities, such as reducing blood pressure, anti-epileptic, anti-tumor, and protecting nerve, etc. With the increasing demand for gastrodin in the market and the inherent problems of traditional methods on obtaining gastrodin, new methods are urgently needed to solve various difficulties in the actual production of gastrodin. Biosynthesis is a new method instead of the traditional acquisition method, and has made great progress and achievements in gastrodin acquisition. Therefore, it is necessary to systematically review the biosynthesis of gastrodin from three aspects of biosynthetic pathway, plant transformation and microbial transformation in this paper, hoping to provide valuable reference for further improvement and perfection of gastrodin production method in the future to meet public increasing demand for gastrodin.
