fennel (foeniculum vulgare mill.) is an industrial medicinal plant with different pharmaceutical and food applications. in this study, the leaf essential oil composition of 12 iranian accessions of fennel collected from different geographical regions was assessed. the essential oil yield of fennel leaves ranged from 0.65% (varamin accession) to 2.03% (tabriz accession). trans-anethole, fenchone...

Background and Aim: Sciatic nerve injury is a common condition that can lead to significant functional deficits. Although current treatments are effective in reducing symptoms, more safer still required. In this research, the effect of trans-anethole (TA) was investigated on improving sciatic function rat model. Methods Materials/Patients: Twenty-eight adult male Wistar rats were divided into f...

Star anise (Illicium verum) is widely used as a medicinal herb and spice. The extracts, essential oil oleoresin, can be produced by hydro-distillation steam distillation, while solvent supercritical fluid extraction to extract oleoresin. In this work, the star distilled obtain oil, subsequently, its residue extracted get Whole grounded fruit for 8, 12, 16, 20, 24 hours, thus highest yield obtai...

Essential oil of star anise as well as phenylpropanoids and sesquiterpenes, for example, trans-anethole, eugenol, β-eudesmol, farnesol, β-caryophyllene and β-caryophyllene oxide, which are present in many essential oils, were examined for their antiviral activity against herpes simplex virus type 1 (HSV-1) in vitro. Antiviral activity was analyzed by plaque reduction assays and mode of antivira...

Basil (O. gratissimum L) is a aromatic and medicinal plant widely used in traditional medicine in Morocco. The aim of this work was to study the effect of three plant growth regulators gibberellic acid (GA), indole 3-acetic acid (IAA) and benzylaminopurine (BAP) on the content and composition of essential oils of this plant, especially on the main compound (methyl chavicol) and its isomer (the ...

Trans-anethole was studied for antifertility activity in rats at dose levels of 50 mg, 70 mg and 80 mg/kg po. Dose-dependent activity was observed, a 100% anti-implantation activity being achieved at 80 mg/kg, po. The compound showed a significant estrogenic activity and did not possess anti-estrogenic, progestational, anti-progestational, androgenic or anti-androgenic activities. In an earlier...

This study aims to develop eco-friendly botanical pesticides. Dried fruits of star anise (Illicium verum Hook.f. (Austrobaileyales: Schisandraceae)) were extracted with methyl alcohol (MA), ethyl acetate (EA), and petroleum ether (PE) at 25°C. The constituents were determined by gas chromatography-mass spectrometry, and the repellency and contact toxicity of the extracts against Sitophilus zeam...

Certain alkenylbenzenes (AB), flavoring chemicals naturally occurring in spices and herbs, are established to be cytotoxic and hepatocarcinogenic in rodents. The purpose of the present study was to determine the DNA damaging potential of key representatives of this class using the Turkey Egg Genotoxicity Assay. Medium white turkey eggs with 22- to 24-day-old fetuses received three injections of...
