- Abstract: In order to provide a theoretical basis for the regulation of active ingredient, the terpenoids metabolic pathway and specific enzymes in Blumea balsamifera are investigated. Basing on transcriptome information, B. balsamifera terpenoids metabolic pathway was analyzed in KEGG data base. Four metabolic pathway of terpenoids were found in KEGG data base. They were terpenoid backbone biosynthesis, monoterpenoid biosynthesis, diterpenoid biosynthesis, sesquiterpenoid and triterpenoid biosynthesis, contained 103, 10, 29,59 genes, respectively. Through the analysis of the enzyme and product in the pathway, the result showed that there were 8 kinds of monoterpenes, 3 kinds of diterpenes, 3 kinds of triterpenes and sesquiterpenes. The mainly key enzymes were deoxyxylulose 5-phosphate synthase, HMG-CoA reductase and allyl transferase system. In B. balsamifera, there were relatively few monoterpenes synthetic enzymes, while the type of products was much more than other terpenes. This may be relate to the non-specific catalytic characteristic of monoterpene synthase. It is expected to improve the yield of terpenoids in B. balsamifera by analysis the pathways and regulation the key enzymes.
