Intraindividual variations of volatile terpene contents in Pinus caribaea needles and its possible relationship to Atta laevigata herbivory
TL;DR: Results indicate that intraindividual variations in the contents of volatile terpenes in Pinus caribaea needles are significant even in regard to interindividual differences, and could be related to the foraging pattern of the leafcutting ant Atta laevigata.
Journal ArticleDOI
Carum copticum and Thymus vulgaris oils inhibit virulence in Trichophyton rubrum and Aspergillus spp
TL;DR: Thymol and T. vulgaris with flu Conazole can be exploited to potentiate the antifungal effects of fluconazole against drug-resistant strains of T. rubrum and Aspergillus spp.
Journal ArticleDOI
Effects of cyclamen mite (Phytonemus pallidus) and leaf beetle (Galerucella tenella) damage on volatile emission from strawberry (Fragaria x ananassa Duch.) plants and orientation of predatory mites (Neoseiulus cucumeris, N. californicus, and Euseius finlandicus).
TL;DR: The naïve generalist predatory mites, Neoseiulus cucumeris, Neosesiulus californicus, and Euseius finlandicus did not prefer P. pallidus- or G. tenella-damaged plants over intact plants in a Y-tube olfactometer, suggesting that these predatory mite species are not attracted by the herbivore-induced volatiles being released from young strawberry plants.

Variation of Malva sylvestris essential oil yield, chemical composition and biological activity in response to different environments across Southern Italy
Sebastiano Delfine,Mariangela Marrelli,Filomena Conforti,Carmen Formisano,Daniela Rigano,Francesco Menichini,Felice Senatore +6 more
TL;DR: The study demonstrates that the crop performance was greatly influenced by the pedo-climatic conditions, and particularly fertility of the environment and the crop management (water supply) that increased also mallow crop yield.
Journal ArticleDOI
Effect of cold plasma on essential oil content and composition of lemon verbena.
TL;DR: Investigation of low‐pressure cold plasma (LPCP) treatments on the essential oil (EO) content and composition of lemon verbena leaves showed that by increasing the LPCP treatment duration, the EO content was reduced from 1.2 to 0.9%.

A generalization of the retention index system including linear temperature programmed gas-liquid partition chromatography.
H. van Den Dool,P. Dec. Kratz +1 more
TL;DR: The equation given by Kovats for the calculation of the retention index in case of isothermal operation is transformed to a more general form to include also the case of linear temperature programmed operation and gives the same retention index for both ways of operation.
Journal ArticleDOI
Gas‐chromatographische Charakterisierung organischer Verbindungen. Teil 1: Retentionsindices aliphatischer Halogenide, Alkohole, Aldehyde und Ketone
TL;DR: In this article, a simple relation exists between the retention index of a compound on a non-polar stationary phase and its boiling point, which is defined as the ratio of the boiling point of the compound to its retention index.

The identification of sesquiterpene hydrocarbons from gas-liquid chromatography retention data
TL;DR: In this article, the identification of sesquiterpenes by gas-liquid chromatography was evaluated, and the most reproducible form of GLC data was found to be the SESQUERPene data.
