Antiproliferative activity of hexane extract from Tunisian Cistus libanotis, Cistus monspeliensis and Cistus villosus.
Mariem Ben Jemia,Mohamed Elyes Kchouk,Felice Senatore,Giuseppina Autore,Stefania Marzocco,Vincenzo De Feo,Maurizio Bruno +6 more
TL;DR: The chemical composition of the hexane extracts from the three Cistus species can be useful in the chemosystematics of this complex genus and deserve further investigations to determine the compounds, or their combinations, which are the main responsible for the antiproliferative activity and its possible mechanism of action.

Antimicrobial and Insecticidal Activities of the Endemic Thymus broussonetti Boiss. and Thymus maroccanus Ball
TL;DR: The investigation by the agar-diffusion method of the antibacterial activity of EOs proved that they have antibacterial effects against Staphylococcus aureus, Salmonella sp.
Journal ArticleDOI
Essential oil composition of geranium (Pelargonium sp.) from the plains of Northern India
TL;DR: Agarwal et al. as discussed by the authors reported that the geranium oil produced at Lucknow is comparable to that produced in southern hills of India in terms of its citronellol and geraniol content.

Impact of four hemp (Cannabis sativa L.) varieties and stage of plant growth on yield and composition of essential oils
Mahnaz Abdollahi,Fatemeh Sefidkon,M Calagari,Amir Mousavi,M. Fawzi Mahomoodally,M. Fawzi Mahomoodally +5 more
TL;DR: E-caryophyllene was found at the highest percentage in the oils of non-native samples at vegetative stage, and to obtain the highest amount of β-pinene and 1,8-cineole, the flowering and seeding stages of hemp are recommended.

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.
