Dietary seabuckthorn (Hippophae rhamnoides L.) reduces toxicity of oxidized cholesterol in rats

Protective effect of seabuckthorn berry juice against acrylamide-induced oxidative damage in rats

Acrylamide (AA), classified as a probable carcinogen, can be neurotoxic, genotoxic, and can damage DNA. This study explored the ability of seabuckthorn berries juice (SBJ) to alleviate AA-induced toxic injury in rats. Twenty-four adult male Sprague-Dawley (SD) rats were randomly divided into four groups: control group, AA group (40 mg/kg), AA + SBJ (40 mg/kg AA and 5 mL/kg SBJ), and AA + vitamin C (VC) group (positive control group, 40 mg/kg AA and 100 mg/kg VC). At the end of the experiment, rats in AA group showed a marked decrease in the rate of weight gain, hind extremity abduction, and ataxia. Obvious anomalies were seen in plasma biochemical parameters (P < 0.05), and different degrees of injury were observed upon histological examination of five tissues (hippocampus, cerebellum, liver, small intestine, and kidney). Compared to the control group, levels of superoxide dismutase, catalase, and glutathione were significantly decreased, while malondialdehyde was elevated (P < 0.05). SBJ treatment reduced the abnormal of behavior, hematological index, antioxidant enzyme, and tissue damage caused by AA in rats. PRACTICAL APPLICATION: Seabuckthorn berries are wild berries rich in vitamin C and polyphenols, which have good antioxidant properties. In this experiment, SBJ has a significant alleviating effect on AA-induced oxidative damage in rats. Therefore, we speculate that SBJ may relieve the oxidative damage caused by diet or other forms of AA exposure in the general population. At the same time, this experiment also provides new ideas for alleviating AA-induced in vivo toxicity.

Sea buckthorn (Hippophae rhamnoides L.) as a potential source of nutraceutics and its therapeutic possibilities - a review

Sea buckthorn (Hippophae rhamnoides L.) is in the focus of interest mainly for its positive effects on health of both human and animal organisms. The whole plant of sea buckthorn and especially its berries are a source of a large number of different bioactive compounds. The greatest attention has been drawn to its high content of vitamins, minerals, natural antioxidants, n-3 and n-6 fatty acids, and proteins. Sea buckthorn is valued for its antioxidant, cardioprotective, antiatherogenic, antidiabetic, hepatoprotective, anti-carcinogenic, immunomodulatory, antiviral, antibacterial, anti-inflammatory and vasorelaxant effects. Due to these and other positive effects, the plant is included in both human and animal nutrition, in the latter case to increase the biological value of animal products. This review summarises the botanical characteristics of sea buckthorn, lists the bio-active substances contained in individual parts of the plant, their effects in the prevention of a number of different diseases and their possible utilisation in human and animal nutrition.

Sea buckthorn seed oil protects against the oxidative stress produced by thermally oxidized lipids

Thermally oxidized vegetable ghee was fed to the rabbits for 14 days with specific doses of sea buckthorn seed oil (SO). The ghee and SO were characterized for quality parameters and fatty acid composition using GC-MS. Rabbits serum lipid profile, hematology and histology were investigated. Major fatty acids were palmitic acid (44%) and oleic acid (46%) in ghee, while SO contains oleic acid (56.4%) and linoleic acid (18.7%). Results showed that oxidized vegetable ghee increases the serum total cholesterol, LDL-cholesterols, triglycerides and decrease the serum glucose. Oxidized ghee produced toxic effects in the liver and hematological parameters. Sea buckthorn oil supplementation significantly lowered the serum LDL-cholesterols, triglycerides and increased serum glucose and body weight of the animals. Sea buckthorn oil was found to reduce the toxic effects and degenerative changes in the liver and thus provides protection against the thermally oxidized lipids induced oxidative stress.
