The millimetre-wave spectrum of estragole

Chemical Physics Letters, 2013
Abstract The rotational spectrum of estragole has been investigated using a free-jet millimetre-wave spectrometer. Computational chemistry calculations at different levels of theory predict three possible conformers of estragole that are within 200 cm − 1 of each other.

Evaluating the effects on steroidogenesis of estragole and trans-anethole in a feto-placental co-culture model

Molecular and Cellular Endocrinology, 2019
In this study, we determined whether estragole and its isomer trans-anethole interfered with feto-placental steroidogenesis in a human co-culture model composed of fetal-like adrenocortical (H295R) and placental trophoblast-like (BeWo) cells.

Modeling the hydroxylation of estragole via human liver cytochrome P450

Journal of Molecular Modeling, 2021
Natural compounds derived from plants are generally regarded safe and devoid of adverse effects. However, there are individual ingredients that possess toxic, genotoxic, and carcinogenic activities. These compounds when exposed at specific level become hazardous to health. Estragole (1-allyl-4-methoxybenzene) is a common component of spice plants.

Study of the Metabolism of Estragole in Humans Consuming Fennel Tea

Chemical Research in Toxicology, 2009
The metabolism of the potent carcinogen estragole was investigated in humans after consumption of fennel tea by analyses of its metabolites in blood plasma and urine. Stable isotope dilution assays based on LC-MS/MS detection revealed that 1'-hydroxylation of estragole happened very fast as the concentration of conjugated 1'-hydroxyestragole in urine ...

Isomerization of Estragole to Anethole

Synthetic Communications, 1980
Abstract Anethole (trans-isomer, I) is an industrially significant organic which has found use predominantly as a flavor and fragrance (licorice) chemical. I is a component of many essential oils, e.g., fennel oils, from which it is isolated for application.

In vivo genotoxicity of estragole in maleF344 rats

Environmental and Molecular Mutagenesis, 2014
Estragole, a naturally occurring constituent of various herbs and spices, is a rodent liver carcinogen which requires bio‐activation. To further understand the mechanisms underlying its carcinogenicity, genotoxicity was assessed in F344 rats using the comet, micronucleus (MN), and DNA adduct assays together with histopathological analysis.

Estragole, a potential attractant of the winged melon aphid Aphis gossypii

Pest Management Science, 2023
AbstractBACKGROUNDAphids are sap‐sucking insect pests of economic importance. They exhibit polyphenism, producing two kinds of morphotypes; winged (alate) and wingless (aptera) morphs. While wingless morphs can be controlled by insecticides, winged morphs are a challenge for targeted control measures as they can fly.

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

Immunochemical Identification of Hepatic Protein Adducts Derived from Estragole

Chemical Research in Toxicology, 1998
Hepatic protein adducts derived from the allylbenzene food flavor estragole, which is hepatocarcinogenic when given to rodents at high doses, have been identified using immunochemical approaches. Male Fischer 344 rats were given estragole orally and hepatic protein adducts were detected by immunoblotting, using antisera raised by immunizing rabbits ...

Biotransformation of estragole by the plant cultured cells of Caragana chamlagu

Plant Biotechnology, 2011
Estragole (EG) is biosynthesized in herbs including anise, basil, bay, tarragon, fennel and marjoram, and is thought to be a useful biomass for the food and health industries. Moreover, the metabolites from estragole are useful intermediates in organic synthetic chemistry.
