چکیده

The present study investigated the effect of sumac (SWE) and Rosemary water extracts (RWE) on microbial growth in ground beef meat during refrigerated storage. The meat samples were explored for changes in TVC, E.coli (0157:H7) and S.aureus populations. Antimicrobial effectiveness of extracts was more pronounced against Gram-positive strain compared with Gram-negative strain. Antimicrobial impact of extracts was also studied on ground beef meat. It was observed that antimicrobial activity of the water extracts was mostly dependent on the types of microorganisms present in meat. The greatest antimicrobial effect of SWE and RWE was found on S.aureus. Furthermore, the antimicrobial activity of RWE was lower than that of SWE. The results indicated the strong potential of SWE and RWE as a natural preservative for ground beef meat.

People believe that sumac is used as reducing fat. In the present study, the hypolipidemic effect of sumac fruits was compared with lovastatin in patients suffered hypercholesterolemia. In a randomized double-blinded-controlled trial, 172 patients diagnosed as hypercholesterolemia (high LDL level) and indicated for lipid-lowering schedules were randomly allocated to receive lovastatin (20 mg/da...

Background: Few anthelmintics are available for the treatment of hydatid disease caused by the parasite Echinococcus granulosus. The appearance of resistance to synthetic anthelmintics and the adverse side effects of chemical drugs, stimulated the research of alternatives, such as medicinal plants. In the present study, the scolicidal effect of methanolic extract of sumac (Rhus coriaria) was in...

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...

In this experimental study, 30 adult male Wistar rats divided into 5 groups (n=6). Experimental rats were treated with one intraperitoneal injection of 120 mg/kgbw Alloxan monohydrate alone or in combination with 28 days of oral administration with aqueous extract of Rhus coriaria (50, 100 and 250 mg/kgbw) while the control rats received normal saline. At the end of the study, blood glucose, ma...
