Objective: To investigate the antioxidant capacity of aqueous extract from Cordia dichotoma (C. dichotoma) fruits in-vitro and their effect on nutritional parameters in rats fed on high-fat diet. Methods: In-vitro antioxidant capacity of C. dichotoma extract were evaluated and compared to two standard materials, ascorbic acid and butylated hydroxytoluene. Metabolic experiments were set out using rats fed on high-fat diet. The extract was tested with two dosages: 0.5 and 1.0 g/kg body weight/ day for four weeks. Lipid constituents of diet and faeces and lipid profile of serum and liver were determined. Results: The administration of the C. dichotoma extract with two dosages caused a significant improvement in the lipid metabolism of rats, compared to the hyperlipidemic control which showed significant disturbance in lipid profile. C. dichotoma extract reduced total body weight gain and total feed intake, and enhanced the fresh and dry weight of faecal excretion. The superior effect was recorded with the high dosage of extract. C. dichotoma minimized fat and cholesterol intake significantly and maximized those in faecal excretions in comparison with hyperlipidemic control values, and low dosage was better than the high one. C. dichotoma extract at two dosages normalized the lipid profile of the serum and liver compared with hyperlipidemic control. Conclusions: The protective effect of C. dichotoma extract against hyperlipidemia may be attributed to the reduced ability of an animal to ingest and absorb fat and cholesterol, and enhanced ability to get rid of them in faecal excretion.

Objective To evaluate in-vitro antioxidant, anti-inflammatory and antitumor abilities against human breast adenocarcinoma (MCF7) and human prostate cancer (PC3) as well as the suppressor effect of bacterial exopolysaccharide (BAEPS) on Ehrlich ascites carcinoma (EAC). Methods In-vitro antioxidants characters of BAEPS were determined using various methods, while anti-inflammatory activity was estimated against cyclooxygenase (COX-1 and COX-2). In-vitro study, anticancer against MCF7 and PC3 were assessed by the mitochondrial dependent reduction of yellow MTT. In in-vivo study against EAC progression, mice were inoculated with EAC cells and then were orally administered BAEPS at 200 mg/kg after 24 h (equals to 0.10 of determined LD

Objective To evaluate the hypocholesterolemic and hypotriglyceridemic activities of four Marrbium vulgare herb extracts using Triton WR-1339-induced hyperlipidemia in mice. Methods Hyperlipidemia was developed by intraperitoneal injection of Triton (200 mg/kg body weight). The animals were divided into main four groups of eight mice each: normal control group, hyperlipidemic control group, hyperlipidemic plus tween-40 control and treated group. The fourth one was divided into four subgroups, petroleum ether extract group, chloroform extract group, ethyl acetate extract group and methanol extract treated group each of them contains two sub-sub group for treating animals with two doses at 0.1 and 0.25 LD
