[Effects of mineral nutrition on metabolism of flavonoids in medicinal plants].

Flavonoids are an important effective component of traditional Chinese medicine, which are widely distributed in the plant kingdom. The biosynthesis of flavonoid in plants is affected and regulated by various environmental factors. For a necessary environmental factor to plant growth and development, mineral nutrients are paid more and more attention on the regulation to the metabolism of flavonoids in medicinal plants. In this paper, an overview of flavonoids biosynthetic pathway, and the macroelements, microelements and rare earth elements on the metabolism of flavonoids in medicinal plants are presented. And the regulation mechanism of them are also analyzed and discussed.
