Triterpenes are group of biologically active compounds which can be found in higher plants. Their main source are plants bark, leaves, twigs, fruits, resins or oils. The biological activity of triterpens is very diversified and many studies have already confirmed the following therapeutic effects: anti-inflammatory, antimicrobial, antiviral, antifungial, immunomodulatory, and hepatoprotective. Synthesis of triterpenes derivates can be performed by chemical or enzymatic reactions, however biotransformation is more specific and eliminates the side products and the molecule alterations. These processes use isolated enzymes or microorganisms. Cell culture in vitro eliminates problems like extract variability as well as instability of the compounds being obtained during the extraction process. What is more, it ensures high reproducibility and optimal regio-and enantioselectivity. The most widely used technique is a classical screening of a series of microbial strains. Studies on triterpene biotransformation give a lot of information about new biologically active compounds and let predict the metabolism of biological compounds. This review presents most important advancements in the metabolic engineering of microorganisms for the production of triterpenoids. Moreover, the review highlights general strategies to obtain rich biochemical diversity of plants by employing the biocatalysts produced by microorganisms or tissue cultures.

Gas chromatographic analysis of the volatile terpenes of the leaves, buds, and twigs of white spruce has confirmed that major changes take place only in the new shoots during the early part of summer. Minor changes were recorded for the older shoots during the same period. The relative amounts of β-pinene, limonene, and myrcene in the volatile oil of the buds change significantly during fall and winter. In contrast, the volatile oil of the leaves and twigs remains constant in quantitative composition during late summer, fall, and winter. The sequence in which the relative amounts of each terpene are laid down in the new growth is complex and no correlation with accepted biosynthetic pathways for monoterpenes could be found. During May substantial amounts of sesquiterpenes are present in the new growth, but these appear to be metabolized further as the summer progresses. The implications for chemosystematic studies are discussed.
