Synthesis and Characterization of Isothiocyanate Poly(Methyl Eugenol) and Thiosemicarbazide Poly(Methyl Eugenol)

Materials Science Forum, 2022
Abstract. This study investigates the synthesis, chemical, and physical properties of isothiocyanate poly(methyl eugenol) or IPME and thiosemicarbazide poly(methyl eugenol) or TPME. The IPME synthesis as a precursor was firstly carried out by reacting Methyl Eugenol (ME) with potassium hydrogen sulfate and potassium thiocyanate in chloroform solution ...

Determination of estragole, safrole and eugenol methyl ether in food products

Food Chemistry, 2003
Abstract A rapid and effective procedure for the extraction and determination of 4-allylanisole (estragole), 4-allyl-1,3-benzodioxole (safrole) and 4-allyl-1,2-dimetoxybenzene (eugenol methyl ether) in food products was developed. These compounds were isolated from food matrices by employing a simultaneous distillation–extraction (SDE) technique with

Effects of eugenol, α-terpineol, terpin-4-ol, and methyl eugenol on consumption of alfalfa pellets by sheep

Small Ruminant Research, 2007
Abstract Many secondary compounds are typically present in unpalatable shrubs on arid and semi-arid rangelands. However, the relationship between intake by livestock and concentration of individual chemicals has been examined for very few of these compounds. Four experiments were conducted to examine effects of individual volatile compounds on intake

Pharmacophagy of Methyl Eugenol by Males Enhances Sexual Selection of Bactrocera carambolae

Journal of Chemical Ecology, 2007
After pharmacophagy of methyl eugenol (ME), males of Bactrocera carambolae (Diptera: Tephritidae) produced (E)-coniferyl alcohol (CF) along with its endogenously synthesized pheromonal compounds. CF was shown to be released into the air by the ME-fed males only during the courtship period at dusk and attracted significantly more males and females than ...

Action of eugenol as a retarder against polymerization of methyl methacrylate by benzoyl peroxide

Biomaterials, 1997
This study was undertaken to examine an effect of eugenol on polymerization of methyl methacrylate (MMA) by benzoyl peroxide (BPO) and 2,2'-azobisisobutyronitrile (AIBN) in the presence of eugenol. The induction period and initial rate of polymerization (IRP) were determined from polymerization curves of MMA using differential scanning calorimetry (DSC)

Metabolism of Alkenebenzene Derivatives in the Rat. II. Eugenol and Isoeugenol Methyl Ethers

Xenobiotica, 1976
1. The metabolites of 3,4-dimethoxyallylbenzene (eugenol methyl ether) and 3,4-dimethoxypropenylbenzene (isoeugenol methyl ether) in the rat were identified and quantitatively determined by g.l.c. and g.l.c.-mass spectrometry. 2. The major metabolic reactions of 3,4-dimethoxyallylbenzene were oxidation of the allylic side chain to 2-hydroxy-3-(3,4 ...
