Retention Indices for Frequently Reported Compounds of Plant Essential Oils
Retention Indices for Frequently Reported Compounds of Plant Essential Oils V. I. Babushok,a) P. J. Linstrom, and I. G. Zenkevichb) National Institute of Standards and Technology, Gaithersburg, Maryland 20899, USA (Received 1 August 2011; accepted 27 September 2011; published online 29 November 2011) Gas chromatographic retention indices were evaluated for 505 frequently reported plant essential oil components using a large retention index database. Retention data are presented for three types of commonly used stationary phases: dimethyl silicone (nonpolar), dimethyl sili- cone with 5% phenyl groups (slightly polar), and polyethylene glycol (polar) stationary phases. The evaluations are based on the treatment of multiple measurements with the number of data records ranging from about 5 to 800 per compound. Data analysis was limited to temperature programmed conditions. The data reported include the average and median values of retention index with standard deviations and confidence intervals.

Chickos* and William Hanshaw 4 Department of Chemistry and Biochemistry, University of MissourisSt. Louis, St. Louis, Missouri 63121 5 6 The temperature dependence of gas chromatographic retention times for n-heptadecane to n-triacontane 7 is reported. These data are used to evaluate the vaporization enthalpies of these compounds at T ) 298.15 8 K, and a protocol is described that provides vapor pressures of these n-alkanes from T ) 298.15 to 575 9 K. The vapor pressure and vaporization enthalpy results obtained are compared with existing literature 10 data where possible and found to be internally consistent. Sublimation enthalpies for n-C17 to n-C30 are 11 calculated by combining vaporization enthalpies with fusion enthalpies and are compared when possible 12 to direct measurements. 13 14 Introduction 15 The n-alkanes serve as excellent standards for the 16 measurement of vaporization enthalpies of hydrocarbons.1,2 17 Recently, the vaporization enthalpies of the n-alkanes 18 reported in the literature were examined and experimental 19 values were selected on the basis of how well their 20 vaporization enthalpies correlated with their enthalpies of 21 transfer from solution to the gas phase as measured by gas 22 chromatography.3 A plot of the vaporization enthalpies of 23 the n-alkanes as a function of the number of carbon atoms 24 is given in Figure 1. -

When used as a pesticide, it is primarily a mosquito and tick repellent, or used against mites. Most studies show geraniol poses little risk to the environment or human health, although a portion of the population suffers from sub-lethal allergies upon dermal or inhalation exposure. Pesticidal Uses: As a pesticide, geraniol is used as a mosquito and tick repellent and as an insecticide for other target pests (including mites). It has antimicrobial and fungicidal applications as well. Formulations and Combinations: Often formulated with other essential oils, including citronellol, farne- sol, nerolidol, eugenol, thymol, lemongrass oil, cinnamon oil and cedarwood oil. May be formulated with sodium lauryl sulfate, glycerin, isopropyl myristate, ethyl lactate, cinnemaldehyde, 2-phenylethyl propio- nate, potassium sorbate and mineral oil. -

This study describes the cloning and functional characterisation of PmSTPS1 and PmSTPS2, two sesquiterpene synthase genes that were identified from P. minus transcriptome data mining. The full-length sequences of the PmSTPS1 and PmSTPS2 genes were expressed in the E. coli pQE-2 expression vector. The sizes of PmSTPS1 and PmSTPS2 were 1098 bp and 1967 bp, respectively,with open reading frames (ORF) of 1047 and 1695 bp and encoding polypeptides of 348 and 564 amino acids, respectively. -
