The increase in the resistance to antimicrobial drugs in use has attracted the attention of the scientific community, and medicinal plants have been extensively studied as alternative agents for the prevention of infections. The Candida genus yeast can become an opportunistic pathogen causing disease in immunosuppressive hosts. The purpose of this study was to evaluate dichloromethane and metha...

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 ...

An improved HPLC method is reported for the determination of rosemary's principal phenolic antioxidants, rosmarinic and carnosic acids, providing a fast and simultaneous determination for both of them by using a solid phase column. The analysis was performed with fresh methanolic extractions of Rosmarinus officinalis. To quantify the amount of antioxidants in a fast and reproducible way by mean...

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...

For this purpose, ad gamma rays in the presence (experimental) or absence (control) of r were necropsied and their blood was collected at days 1, 3, 5, 10 number of erythrocyte and leucocyte counts, hemoglobin content control group; whereas a recovery pattern was recorded in e hematological p...

in this work, copper oxide nanoparticles have been synthesized via extractive rosmarinus officinalis leaves by simple and economic co-precipitation method at ambient conditions which it has used (ch3coo)2cu+h2o individually as cu sources. it was found that uniform copper oxide nanoparticles have been successfully produced at various temperature, namely 400, 600, and 800 0c. powder x-ray diffrac...

abstract background and purpose: in traditional medicine, herbal products still remain the principal source of pharmaceutical agents. the present study aimed to investigate the antifungal effects of echinophora platyloba and rosmarinus officinalis extracts on c. albicans species. materials and methods: the aqueous and ethanolic leaf extracts of e. platyloba and r. officinalis, collected from th...
