The present study aims to investigate the bioactive compounds content and antioxidant activity of the agricultural remnants (strawberry and cauliflower leaves). This study will also see if eating strawberry and cauliflower leaves powder can help with the complications associated with obesity in rats. Data indicated that the bioactive compounds assayed content was ranged as follow: total phenolics from 189.15 to 233.94 mg EGA.100 g-1, total carotenoids from 39.56 to 47.21 mg.100 g-1, total flavonoids from 42.83 to 52.06 mg RE.100 g-1, lutein from 53.17 to 56.4 mg.100 g-1, total anthocyanin's from 19.21 to 23.96 mg.100 g-1, total chlorophylls from 306.32 to 349.73 mg.100 g-1, and dietary fiber from 23.44 to 28.06 g.100g-1. Also, the hydro-ethanolic extract of strawberry and cauliflower leaves demonstrated a wide range of antioxidant activity. For the all plant parts tested and their mixture, a positive and highly significant (p≤ 0.05) relationships between total bioactive compounds assayed and antioxidant activity was recorded. Normal rats fed diet-induced obesity (DIO) (model control) had higher body weight than the control/normal group. At the end of the experiment (8 weeks), rats of the normal group recorded increasing on body weight rate by 77.57% from the starting point of the experiment while obese group was 1114.60%. Dietary intervention with the tested plant parts and their mixture on the diet by 10% induced significant (p≤ 0.05) decreasing on body weight, improving of the serum lipid profile parameters, decreasing of the oxidative stress and positively manipulated obesity-related histopathological changes in adipose tissues of the obese rats. These data support the use of strawberry and cauliflower leaves for obesity treatment and prevention. Furthermore, the findings suggest the benefits of dietary changes, such as strawberry and cauliflower leaves supplementation, in reducing the complications linked with obesity, such as oxidative stress problems. |
