Kinetics of anionic polymerization of β‐myrcene in hydrocarbon solvents

Polymer International, EarlyView.
The process of anionic polymerization of β‐myrcene in hydrocarbon solvents was examined by kinetic studies and quantum chemical calculations. Abstract The kinetics of anionic polymerization of β‐myrcene initiated by sec‐butyllithium were examined in saturated and unsaturated hydrocarbon solvents, i.e. cyclohexane, cyclohexene, 4‐vinylcyclohexene and dl‐

PERCOBAAN FRAKSIONASI-DISTILASI MINYAK TERPENTIN DARI PINUS MERKUSII JUNG ET DE VRIESE

Jurnal Penelitian Hasil Hutan (Journal of Forest Products Research), 2017
Turpentine  oil  was optained  from  rosin  factory   in Paninggaran,   Central  Java,  and  Sukun,  East  Java.   Both  samples were  separated   by  fractional  distilation   into  several  fractions.

Unsaturated biobased polyesters from bicyclic α‐pinene‐based diols

Polymer International, EarlyView.
We present the synthesis of four biosourced unsaturated polyesters made from chiral terpene‐based diols and esters of renewable diacids. The resulting materials harbor a bicyclic pinene ring in their backbones which leads to enhanced thermal properties while still conferring susceptibility to enzyme hydrolysis for chains having a cis alkene.

Chemical Compositions and Enantiomeric Distributions of Foliar Essential Oils of Chamaecyparis lawsoniana (A. Murray bis) Parl, Thuja plicata Donn ex D. Don, and Tsuga heterophylla Sarg.

Plants
As part of our continuing interest in the essential oil compositions of gymnosperms, particularly the distribution of chiral terpenoids, we have obtained the foliar essential oils of Chamaecyparis lawsoniana (two samples), Thuja plicata (three samples ...

Composition and Seasonal Variation of the Essential Oil from from Hokkaido, Japan

Natural Product Communications, 2009
The composition of the steam-distilled essential oil from the leaves of Abies sachalinensis (F. Schmidt) Mast. cultivated in Hokkaido (Japan) was studied by GC-MS. The seasonal variation in the main volatile constituents was also investigated.

A walk in the park—Identifying healthy greenspaces using scents

PLANTS, PEOPLE, PLANET, EarlyView.
As urbanisation accelerates globally, access to nature is increasingly recognised as vital for public health and wellbeing. We captured and analysed plant‐emitted airborne ‘scent signatures’ across Oxford's urban greenspaces to assess their potential health relevance.

Compositional and Enantiomeric Analysis of the Essential Oil of from India

Natural Product Communications, 2016
The leaf essential oil composition of Taxodium distichum L., collected from the foothills of Uttarakhand, India was analyzed using gas chromatography-flame ionization detection (GC-FID) and gas chromatography-mass spectrometry (GC-MS) equipped with DB-5 (

Aboveground herbivory elevates belowground rhizosphere volatile organic compound concentrations in ambient and polluted air, independent of volatile sampling methodology

PLANTS, PEOPLE, PLANET, EarlyView.
The effect of air pollution on plants is still underexplored, especially belowground. We used a field facility that released diesel exhaust and ozone at concentrations equivalent to those near a busy road in Reading, UK, to measure belowground gas exchange of Scots pine together with feeding by large pine weevils, a major pest of conifers.

Microbiota‐Mediated Sequential Gallery Colonization by Adults and Larvae of an Invasive Bark Beetle

Integrative Zoology, EarlyView.
Dispersing adult beetles harbor more pinitol‐degrading microbes to colonize novel host pines with high levels of pinitol stress. These microbes from the beetle's exoskeleton and gut will be transmitted into the gallery via adults’ feeding and frass, whose proliferation in the gallery contributes to the formation of a low‐pinitol microhabitat.

Rosmarinus officinalis essential oil components promote anaesthesia in Colossoma macropomum (Cuvier, 1818) through behavioural and cardiorespiratory modulation

Journal of Fish Biology, EarlyView.
Abstract Anaesthetic management plays a crucial role in maintaining the welfare and physiological stability of fish during routine aquaculture and research procedures. The essential oil of Rosmarinus officinalis (ROEO) has emerged as a promising natural anaesthetic; however, its cardiophysiological effects in Amazonian species remain underexplored ...
