Antioxidant activity and α-glucosidase inhibition by essential oils from Hertia cheirifolia (L.)
Kaouther Majouli,Malek Besbes Hlila,Assia Hamdi,Guido Flamini,Hichem Ben Jannet,Abderraouf Kenani +5 more
TL;DR: In this paper, the essential oils from Hertia cheirifolia L. were evaluated for antioxidant activities by the 1,1-diphenyl-2-picrylhydrazyl (DPPH), reducing power and carotene/linoleic acid and inhibitory properties against αglucosidase.

Insecticidal formulation based on Xylopia aethiopica essential oil and kaolinite clay for maize protection
TL;DR: Insecticidal formulations based on the essential oil of Xylopia aethiopica and kaolinite-clay (particles size less than 50 μm) are efficient in protecting stored grains and depended on storage conditions and duration.
Journal ArticleDOI
In vitro antimicrobial and antiviral activities of the essential oil and various extracts of Salvia cedronella Boiss.
TL;DR: The methanol extract showed a good anti-influenza virus effect, the growth of both A/Weybridge and A/Aichi was reduced significantly and a positive correlation was observed between biological activity potential and amount of phenolic compounds of the extracts.
Journal ArticleDOI
Chemical composition of essential oils and in vitro antioxidant properties of extracts and essential oils of Calamintha origanifolia and Micromeria myrtifolia, two Lamiaceae from the Lebanon flora
TL;DR: In this paper, the chemical composition of essential oils of Calamintha origanifolia (Labill.) Boiss and Micromeria myrtifolia Boiss, two Lamiaceae species collected in Lebanon, and to characterize the in vitro antioxidant activities of their extracts and of the essential oils.
Journal ArticleDOI
Constituents of Cajanus cajan (L.) Millsp., Moringa oleifera Lam., Heliotropium indicum L. and Bidens pilosa L. from Nigeria.
TL;DR: The essential oils of four plant species from Nigeria have been extracted by hydrodistillation and analyzed by GC and GC-MS, and the observed chemical patterns differ considerably from previous investigations.

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.

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.
