Abstract:
Background
Nigella sativa grain has a rich medical and religious history and consists of powerful chemical compounds that can have many effects on human health. In this study the effect of ethanolic extract of Nigella sativa on antioxidant properties has been investigated.
Methods
The present study was carried out on 28 adult female Wistar rats (weighing 160 - 200 g) in 4 groups (7 mice per group). The 1st group (control group) received no treatment, the 2nd and 3rd groups were treated orally with alcoholic extract of Nigella sativa, at a dose of 400 mg / kg of body weight for 21 days. In addition to oral treatment, the 3rd group was also treated with immobilization stress, and the 4th group was only given immobilization stress. Malondialdehyde (MDA), Ferric Reducing / Antioxidant Power (FRAP) and Catalase (CAT) were measured in liver and kidney. Furthermore, the fatty acids profile of the extracted oil was studied. In addition, the proximate chemical composition and the contents of Calcium and phosphorous of Nigella sativa L. seeds was investigated to 5 times. The results of the study were analyzed using one-way ANOVA and mean comparison was conducted using Tukey’s test at significance level of (P
Results
The results showed Nigella sativa to be rich in fatty acids, especially linoleic, oleic, palmitic, stearic, and linolenic acids were amounting (46.05 ± 1.3, 33.46 ± 1.02, 15.05 ± 0.65, 3.46 ± 0.13, 1.98 ± 0.04%, respectively. P
Conclusions
The results of this study show that extract of Nigella sativa to have necessary chemical characteristics increases antioxidant capacity. Moreover, reduces lipid peroxidation (Oxidative stress) and also the harmful effects of stress on the body’s tissues.
