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.

The Following Carcinogenic Essential Oils Should Not Be Used In
Aromatherapy Undiluted- Safety and Ethics Copyright © Tony Burfield and Sylla Sheppard-Hanger (2005) [modified from a previous article “A Brief Safety Guidance on Essential Oils” written for IFA, Sept 2004]. Intro In the last 20 years aromatherapy has spread its influence to the household, toiletries and personal care areas: consumer products claiming to relax or invigorate our psyche’s have invaded our bathrooms, kitchen and living room areas. The numbers of therapists using essential oils in Europe and the USA has grown from a handful in the early 1980’s to thousands now worldwide. We have had time to add to our bank of knowledge on essential oils from reflecting on many decades of aromatherapeutic development and history, the collection of anecdotal information from practicing therapists, as well as from clinical & scientific investigations. We have also had enough time to consider the risks in employing essential oils in therapy. In the last twenty years, many more people have had accidents, been ‘burnt’, developed rashes, become allergic, and become sensitized to our beloved tools. Why is this? In this paper, we hope to shed light on this issue, clarify current safety findings, and discuss how Aromatherapists and those in the aromatherapy trade (suppliers, spas, etc.) can interpret this data for continued safe practice. After a refresher on current safety issues including carcinogenic and toxic oils, irritant and photo-toxic oils, we will look at allergens, oils without formal testing, pregnancy issues and medication interactions. We will address the increasing numbers of cases of sensitization and the effect of diluting essential oils. -
Visible-Light-Driven Photooxidation of Alcohols Using Surface-Doped Graphitic Carbon Nitride
Electronic Supplementary Material (ESI) for Green Chemistry. This journal is © The Royal Society of Chemistry 2017 Visible-Light-Driven Photooxidation of alcohols using surface-doped graphitic carbon nitride Wuyuan Zhang, Anna Bariotaki, Ioulia Smonou, and Frank Hollmann* Material and Methods Materials Unless stated otherwise all chemicals were purchased from Sigma-Aldrich, Fluka, Acros or Alfa-Aesar with the highest purity available and used without further treatment. Synthesis of g-C3N4 and carbon nanodots doped (CD-C3N4) The g-C3N4 was synthesized via the simple calcination (Carbolite furnace; CWF 12/5, 2400 W) of urea (10.0 g) at 600 °C for 4 h (5 °C/min), a yellowish powder was obtained after the cooling to room temperature.1 The carbon nanodots were synthesized via the thermal decomposition of sucrose with slight modification.2 Briefly, 0.75 g of sucrose was dissolved in 30 mL of MilliQ water and stirred at room temperature for 0.5 h. The solution was transferred into a 45 mL Teflon-lined stainless steel autoclave reactor, and heated at 180 °C for 5 h (10 °C/min). After cooling the reactor to room temperature, a brown mixture was obtained. The mixture was centrifuged (8000 rpm for 20 min), and the pellet was washed with water (3×) and freeze-dried. 3 In order to deposit carbon nanodots to the surface of g-C3N4, Liu et al’s procedures were adopted. Firstly, a stock solution of carbon nanodots (1 mg in 25mL water) was prepared. 15.0 mL of this stock solution was mixed with 15.0 mL of NH4OH (28 %) and sealed in a 45 mL Teflon-lined autoclave reactor. -

ABSTRACT Oxidation of 4-Methoxybenzyl alcohol by different Cr (VI) oxidants [PDC and PCC] has been studied in acetic acid-H2O medium in the presence of PTSA spectrophotometrically. The reactions are found first order with respect to both the oxidants, [H+], and [substrate].Michaelis-Menten type kinetics is observed. The reaction rate decreases with increasing volume percentage of acetic acid in reaction mixture. The reaction was studied at different temperature [298-318 K] and activation parameters were computed. The oxidation product was identified as Cr (III) and corresponding aldehyde. The oxidation rate order was found with respect to the oxidants are: PCC > PDC KEYWORDS Oxidation, 4-Methoxybenzyl alcohol, PTSA, PCC and PDC. 1.

Effect of Different Extraction Methods on Yield and Quality of Essential Oil from Four Rosa Species
Floriculture and Ornamental Biotechnology ©2007 Global Science Books Effect of Different Extraction Methods on Yield and Quality of Essential Oil from Four Rosa Species Adnan Younis1* • Muhammad Aslam Khan1 • Asif Ali Khan2 • Atif Riaz1 • M. Aslam Pervez1 1 Institute of Horticultural Sciences, University of Agriculture, Faisalabad, Pakistan 2 Department of Plant Breeding and Genetics, University of Agriculture, Faisalabad, Pakistan Corresponding author : * [email protected] ABSTRACT In the present study rose oil was extracted from the petals of four Rosa species i.e. R. damascena, R. centifolia, R. borboniana and Rosa 'Gruss an Teplitz' through solvent extraction through hexane, solvent extraction through ether and steam distillation. R. damascena yielded (0.145%) of absolute oil, R. centifolia yielded 0.11% whereas R. 'Gruss an Teplitz' yielded the least (0.035%) absolute oil. Solvent extraction through hexane yielded more absolute oil (0.11%) than steam distillation (0.075%) and solvent extraction (0.07%) through ether on petal weight basis. Gas-chromatography of the rose oil was carried out for the qualitative and quantitative analysis of the oil constituents. Major compounds identified were citronellol, methyl eugenol, geraniol, geranyl acetate, phenyl ethyl alcohol, linalool, benzaldehyde, benzyl alcohol, rhodinyl acetate, citronellyl acetate, benzyl acetate and phenyl ethyl formate. Both techniques (solvent extraction and steam distillation) yielded oil with differences in the percentage composition of each component, but solvent extraction through hexane proved better (i.e. higher yield and more components) than steam distillation for extraction of essential oil from roses. _____________________________________________________________________________________________________________ Keywords: citronellol, essential oil composition, Rosa centifolia, solvent extraction, steam distillation INTRODUCTION essential oil, which is slowly liberated from the plant material (Durst and Gokel 1987; Wilson 1995). -

Calle 64 x Carrera 65 Autopista Norte. AA 3840. Medellín, Colombia. (Recibido el 18 de febrero de 2011. Aceptado el 23 de mayo de 2012) Abstract The biotransformation of trans-cinnamic acid by whole cells of the Colombian native phytopathogenic fungus Colletotrichum acutatum was studied. Initially, fungitoxicity of this compound against C. acutatum was evaluated; trans-cinnamic acid exhibited a moderate to weak toxicity against the microorganism and apparently a detoxification mechanism was present. Then, in order to study such mechanism and explore the capacity of this fungus to biotransform trans-cinnamic acid into value-added products, the microorganism was incubated with the substrate using three different culture media (Czapeck-Dox, Sabouraud and PDB) at room conditions. Using Czapeck-Dox medium, whole cultures of C. acutatum reduced trans-cinnamic acid, first to aldehydes (trans-cinnamaldehyde and 3-phenylpropanal), then to alcohols (cinnamyl alcohol and 3-phenyl-1-propanol). Subsequently, these alcohols were transformed to the corresponding acetyl esters. Nevertheless, some of these products were absent or present at different concentration when culture medium was changed. -
