In plants, sesquiterpenes of different structural types are biosynthesized from the isoprenoid intermediate farnesyl diphosphate. The initial reaction of the biosynthesis is catalyzed by sesquiterpene cyclases (synthases). In Artemisia annua L. (annual wormwood), a number of such sesquiterpene
The essential oil from the herb of Artemisia campestris L. subsp. campestris harvested at five ontogenesis phases was analyzed by GC, GC/MS and 1H NMR spectroscopy. More than 130 compounds were identified. Terpene hydrocarbons dominated in the oil. Germacrene D (20.3-30.1%), β-pinene (3.7-15.4%) and
Most TPSs (terpene synthases) contain plasticity residues that are responsible for diversified terpene products and functional evolution, which provide a potential for improving catalytic efficiency. Artemisinin, a sesquiterpene lactone from Artemisia annua L., is widely used for malaria treatment
