A molecular perspective on terpene variation in Australian Myrtaceae [PDF]

, 2015
The terpenoid-dominated essential oils in Australian Myrtaceae mediate many ecological interactions and are important industrially. Of all the significant essential oil-producing families, Myrtaceae is the only one for which there is no molecular ...

Bioinspired Design and Synthesis of Polyphenolic Star‐Like and Hyperbranched Polyester Models

Chemistry – A European Journal, EarlyView.
Gallotannin‐inspired star‐like and hyperbranched aromatic polyesters were synthesized from D‐glucose and ABn‐type phenolic acid monomers, such as protocatechuic acid. This bioinspired approach afforded polyphenolic polymeric nanoparticles able to encapsulate hydrophobic dyes, opening new perspectives for biobased encapsulation and delivery systems ...

Spatial and developmental expression of key genes of terpene biosynthesis in Tanacetum parthenium

, 2014
Feverfew (Tanacetum parthenium) is a medicinal plant belonging to the Asteraceae family. To improve understanding terpene metabolism in feverfew, the relative gene expression of four key genes coding 3-hydroxy-3-methylglutarylcoenzyme A reductase (HMGR ...

Structure Elucidation and Total Synthesis of Granolides A–C: Ethyl‐branched Sesquiterpenes From the Tropical Frog Gephyromantis granulatus

Chemistry – A European Journal, EarlyView.
Males of the tropical frog Gephyromantis granulatus carry unique ethyl‐branched sesquiterpenoid macrolactones in their scent glands. Their structure elucidation was performed by GC/MS, leading to the proposed structures of the granolides. A flexible enantioselective synthesis confirmed the structures and allowed determination of their absolute ...

Release of multicomponent pheromones from porous fibres

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Surface engineering empowers a polymer exclusion net to serve dual functions: physical exclusion and pheromonal release, allowing for pest control in agricultural crops. In previous work, a net woven from porous fibres releasing simple, single‐component alarm pheromones showed promising results in field tests.
