Chemical composition and phytotoxic effects of essential oils from four Teucrium species.
Laura De Martino,Carmen Formisano,Emilia Mancini,Vincenzo De Feo,Franco Piozzi,Daniela Rigano,Felice Senatore +6 more
TL;DR: The radicle elongation, above all, of radish was significantly inhibited by all oils, in particular by the essential oil of T. arduini, at the highest doses tested.

Detection and Identification of Floral Scent Compounds
Dorothea Tholl,Ursula S. R. Röse +1 more
TL;DR: Several practical approaches to floral scent analysis and their advantages and limitations are discussed in this article, with a selection of collection methods that range from low-tech, inexpensive, quick sampling methods to high-tech methods that require a complicated laboratory setup and can automatically collect samples in short time intervals over several days.

Composition and Antimicrobial Activity of Cymbopogon giganteus (Hochst.) Chiov. Essential Flower, Leaf and Stem Oils from Cameroon
Leopold Jirovetz,Gerhard Buchbauer,Gernot A. Eller,Martin Benoit Ngassoum,Pierre M. Maponmetsem +4 more
TL;DR: Antimicrobial activities of the four oils were found against Gram-(+)- and Gram-(-)-bacteria as well as the yeast Candida albicans, and these results were discussed with the compositions of each sample.

Bactericidal action of lemon grass oil vapors and negative air ions
Amit K. Tyagi,Anushree Malik +1 more
TL;DR: In this paper, the authors investigated the effectiveness of lemon grass oil vapors against Escherichia coli using a special set-up and kill time assays and found that the combination of negative air ion (NAI) with vapor has a greater bactericidal effect than NAI alone (42%) or vapors alone (78%) within 8h exposure.

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.
