The adsorption mechanism of Rosmarinus officinalis L. as corrosion inhibitor for Al AA8801 alloy in 1.0M HCl was studied using gravimetric method and thermodynamics studies at 303, 313, 323 333K. Inhibitor concentrations ranged between 0 1000mg/L. Results show that the is via physisorption, generally endothermic accompanied by a resulting decrease disorder. efficiency largely decreased with inc...

The current study aimed to investigate ethanolic extracts from the following medicinal plant species cultivated in western Romania: Melissa officinalis L., Rosmarinus officinalis L. (RO) and Salvia officinalis L. (SO). Antioxidant activity, total phenolics content and a profile of the main hydroxycinnamic acids (HCAs), including caffeic, ferulic, coumaric and rosmarinic acids, was determined fo...

The MeOH extract of the leaves of rosemary (Rosmarinus officinalis L.) completely inhibited the motility of cultured epimastigotes of Trypanosoma cruzi at the concentration of 2 mg/ml after 2 h of incubation. Activity-guided fractionation of the MeOH extract has resulted in the isolation of three triterpene acids, betulinic, oleanolic and ursolic acids. Ursolic acid stopped the movement of all ...

Bioassays of Rosmarinus officinalis L. essential oil and blends of its major constituents were conducted using host-specific strains of the two-spotted spider mite, Tetranychus urticae Koch, on bean and tomato plants. Two constituents tested individually against a bean host strain and five constituents tested individually against a tomato host strain accounted for most of the toxicity of the na...

Medicinal plants with the hepatobiliary mode of action remain essential therapeutic agents for the treatment of cholestasis. They are denoted as cholagogues (promoting the flow of bile from the liver and gall bladder into the intestines) and choleretics (increasing bile production). Cholagogic and choleretic properties of rosemary (Rosmarinus officinalis) [1] and other medicinal plants have bee...

Salvia rosmarinus Spenn (synonym: Rosmarinus officinalis L.) is economically and medically important grows naturally in Al-Marj (Libya). Macro, micro morphological chemical characteristics were studied. Leaf venation, leaf anatomy compounds of essential oils carried out according to traditional methods. The objective the present study provide detailed description this species. Morphological cha...

the infections risk related to pathogenic germs increases at the present time considering the increased resistance which certain microbes acquire, whose usual antibiotics are ineffective to treat the infectious disease. the aim of this study was to determine antimicrobial effect of the aqueous and ethanolic extracts of lavandula stoechas l. and rosmarinus officinalis l. on listeria monocytogene...
