Effect of monoterpenes on lipid oxidation in maize
The monoterpenes 1,8-cineole, thymol, geraniol, menthol and camphor strongly inhibited the root growth of Zea mays L. seedlings. They induced an oxidative stress as measured by the production of malondialdehyde, conjugated ...
Insecticide and acaricide activities of polyhalogenated monoterpenes from chilean Plocamium cartilagineum
Four new alicyclic monoterpenes based on the 1-(2-chlorovinyl)-2,4,5-trichloro-1,5-dimethylcyclohexane skeleton were isolated from Plocamium cartilagineum from the Chilean coast, together with four known cyclic monoterpenes. ...
Bark and ambrosia beetle (Coleoptera : Scolytidae) responses to volatiles from aging loblolly pine billets
(Amer Entomol Soc, 1999-08-01)
Many species of bark and ambrosia beetles use host volatiles as cues for breeding site location. In a study where the objectives were to identify the different volatiles released by Pinus taeda L. billets as they age, to ...
Antioxidant effects of the monoterpenes carvacrol, thymol and sabinene hydrate on chemical and sensory stability of roasted sunflower seeds
BACKGROUND: Oxidation products and rancid flavors decrease the sensory quality of food products, making them unacceptable to consumers. Synthetic antioxidants are used in many foods to prevent rancidity, though their safety ...
Isolement et synthese de l'espintanol, nouveau monoterpene antiparasitaire
(Journal of Natural Products, 1991)
Abstract.-The in vitro leishmanicidal and trypanocidal activities of a petroleum ether extract of Oxandra espintana have been investigated. Four aromatic monoterpenes were isolated, of which two are novel: espintanol ...
Variations in the halogenated monoterpene metabolites of plocamium cartilagineum of the chilean coast
Examination of six samples of the red alga P. cartilagineum collected along 1600 km of Central Chilean coast yielded a number of polyhalogenated monocyclic monoterpenes. Acyclic compounds were not found. Two common compounds ...
Changes in the composition of phospholipid fatty acids and sterols of maize root in response to monoterpenes
(Springer Verlag Berlín, 2005-07)
Terpenes are thought to be important in plantYplant interactions because of their phytotoxic action on seed germination and growth. Herein, the effects of five volatile monoterpenes on root sterols and phospholipid fatty ...
