Estimation of rate coefficients and branching ratios for gas-phase reactions of OH with aliphatic organic compounds for use in automated mechanism construction [PDF]

open access: yes, 2018
Reaction with the hydroxyl (OH) radical is the dominant removal process for volatile organic compounds (VOCs) in the atmosphere. Rate coefficients for reactions of OH with VOCs are therefore essential parameters for chemical mechanisms used in chemistry ...

Iridoid and Acyclic Monoterpene Glycosides, Kankanosides L, M, N, O, and P from Cistanche tubulosa

open access: yesChemical and Pharmaceutical Bulletin, 2010
Three iridoid glycosides, kankanosides L, M, and N, and two acyclic monoterpene glycosides, kankanosides O and P, were isolated from fresh stems of Cistanche tubulosa (Orobanchaceae) together with eight iridoid glycosides, five acyclic monoterpene glycosides, three phenylpropanoid glycosides, and four lignan glycosides. Their structures were elucidated

Current and Potential Use of Citrus Essential Oils. [PDF]

open access: yes, 2013
Since the Middle Ages, citrus essential oils (EOs) have been widely used for their bactericidal, virucidal, fungicidal, antiparasitical, insecticidal, medicinal and cosmetic proprieties. Also nowadays, they find important applications in pharmaceutical,

Discovery and characterisation of terpenoid biosynthesis enzymes from Daphniphyllum macropodum

open access: yesBMC Plant Biology
Terpene synthase (TPS) enzymes are known to be pivotal in the biosynthesis of terpenoids in plants and microbes. These enzymes catalyse the transformation of ubiquitous acyclic prenyl diphosphate substrates into diverse hydrocarbon skeletons.

Volatile organic compounds: Plant natural defense mechanisms against herbivorous arthropods and an opportunity for plant breeding of cotton [PDF]

open access: yes, 2018
Plants' natural defense mechanisms against herbivorous arthropods include the emission of volatile organic compounds (VOC). Nowadays field observations about plant-insect interactions are better understood thanks to the increasingly scientific ...
