Kinetic study of pilot-scale supercritical CO2 extraction of rosemary (Rosmarinus officinalis) leaves

Supercritical carbon dioxide extraction of antioxidants from rosemary (Rosmarinus officinalis) leaves for use in edible vegetable oils.

Supercritical extraction was employed to produce rosemary (Rosmarinus officinalis L.) extracts with different composition and antioxidant activity. CO₂ was utilized as supercritical solvent and diverse extraction conditions (temperature, pressure, amount of cosolvent and fractionation scheme) were applied. The extracts with higher antioxidant content were selected to study their capability as n...

Antioxidant and antimicrobial activity of extracts obtained from rosemary (Rosmarinus officinalis) and vine (Vitis vinifera) leaves

The antioxidant properties and antimicrobial activity of rosemary extracts were compared to those of vine leaf extracts. The phenolics were quantified by HPLC. Rosemary extracts were stronger in reducing power than vine leaf extracts but possessed weaker superoxide anion radical (O2 ) scavenging capability. The antimicrobial activity was confirmed by the broth microdilution test using minimal i...

Pharmacology of rosemary (Rosmarinus officinalis Linn.) and its therapeutic potentials.

The use of plants is as old as the mankind. Natural products are cheap and claimed to be safe. They are also suitable raw material for production of new synthetic agents. Rosemary (Rosmarinus officinalis Linn.) is a common household plant grown in many parts of the world. It is used for flavouring food, a beverage drink, as well as in cosmetics; in folk.medicine it is used as an antispasmodic i...

Anti-proliferative and antioxidant properties of rosemary Rosmarinus officinalis.

Constituents in rosemary have shown a variety of pharmacological activities for cancer chemoprevention and therapy in in vitro and in vivo models. In order to further explore the chemopreventive properties of crude extracts of rosemary (Rosmarinus officinalis L), we studied its anti-proliferative property on several human cancer cell lines and its antioxidant and anti-inflammatory properties in...
