Anaerobic Degradation of Bicyclic Monoterpenes in Castellaniella defragrans
Metabolites, 2018 The microbial degradation pathways of bicyclic monoterpenes contain unknown enzymes for carbon–carbon cleavages. Such enzymes may also be present in the betaproteobacterium Castellaniella defragrans, a model organism to study the anaerobic monoterpene ...

Adaptation of hydroxymethylbutenyl diphosphate reductase enables volatile isoprenoid production
eLife, 2020 Volatile isoprenoids produced by plants are emitted in vast quantities into the atmosphere, with substantial effects on global carbon cycling. Yet, the molecular mechanisms regulating the balance between volatile and non-volatile isoprenoid production ...

Solubilization of polystyrene into monoterpenes [PDF]
Advances in Polymer Technology, 2008 AbstractThe ability of certain monoterpenes from the essential oils of Abies sachalinensis and Eucalyptus species to dissolve polystyrene (PS) was studied. These two essential oils themselves were also examined. The aim of this study is to recycle PS without a melting process and without using petroleum‐derived solvents.

Oxidative Rearrangements of the Alkaloid Intermediate Geissoschizine
Angewandte Chemie, EarlyView.19E‐geissoschizine is a key precursor in the biosynthesis of monoterpene indole alkaloids such as strychnine, ibogaine, and vinblastine. Using enzymatic assays and gene silencing, three CYPs were identified from C. roseus that oxidize this compound to four alkaloid scaffolds: strychnos, sarpagan, akuammiline, and mavacurane. Mutational analysis reveals

Comparison of terpene components from flowers of Artemisia annua
Bangladesh Journal of Pharmacology, 2012 Terpene constituents of essential oils obtained by steam distillation from Artemisia annua flowers at the pre-, full- and post-flowering stage was investigated by gas chromatography (GC) and gas chromatography-mass spectrometric detector (GC-MS). The aim
