Antioxidant, antibacterial and insecticidal activities of cypress ( L.) essential oil.

The aerial parts of cypress ( L.) of three collect regions (Bizerte, Ben-Arous and Nabeul) were reported for their essential oil (EO) compositions, antioxidant, antimicrobial and insecticidal activities. Results showed that the higher EO yields were observed in Bizerte and Ben Arous (0.

Screening of antimicrobial and insecticidal properties of essential oils extracted from three Tunisian aromatic and medicinal plants.

The essential oils (EOs) of , and have been screened for their insecticidal activity against , and and for their antimicrobial activity against Gram (+), Gram (-) bacteria and against yeast strain. EO showed good insecticidal activity with 24-h against (LC = 29.7) and against (66.

Phenolic constitutents, antioxidant and repellent activities of coriander ( L.) fruits using different solvent extracts.

The organic solvent extracts (hexane, chloroform, acetone, methanol and water) of coriander fruits were reported for their antioxidant and repellent activities. The methanol and acetone extracts revealed the highest antiradical activity as compared to the other solvent extracts. HPLC analysis revealed that phenolic acids were the major compounds in chloroform and acetone extracts, whereas flavonoids in methanol and water extracts.

Coupled extruder-headspace, a new method for analysis of the essential oil components of Coriandrum sativum fruits.

A new method involving concurrent single screw extruder combined with continuous headspace dynamic for the extraction and identification of the essential oil of Coriandrum sativum L. fruit was developed. The effect of six different nozzle diameters (5, 6, 7, 8, 9 and 10 mm) on the content and chemical composition of the essential oil of coriander fruit was studied.

Antioxidant activities of the essential oils and methanol extracts from myrtle (Myrtus communis var. italica L.) leaf, stem and flower.

This study was designed to examine the chemical composition and antioxidant activity of the essential oils and methanol extracts of Myrtus communis var. italica L. leaf, stem and flower.
