Abstract: Purine alkaloids (e.g. caffeine) can be found in many plants. As excessive intake of caffeine could have side effects on human health, it would be of great significance to obtain a low caffeine level cultivar by regulating metabolism of purine alkaloids. The present paper summarized the distribution, biosynthesis and catabolism (including main and minor pathways) of purine alkaloids, then enzymes and cloning of related genes involved in metabolism of purine alkaloids in tea and other plants. Finally, the exiting problems and possible ways of breeding low caffeine tea cultivars are discussed.

Key words: purine alkaloids, metabolism, methyltransferase, gene, decaffeinated
