Through preliminary chemical counting, we found that rapeseed contains flavonoids, alkaloids, saponins, tannins, sterols, triterpenes and reference compounds and is rich in oils. To determine the antioxidant activity, a methanolic extract was prepared, which gave an estimated yield of 6.274%, and the amount of polyphenols and flavonoids in the methanolic extract was estimated as µgAG E/mg EX 0.43±133.7 and µg Qu E/mg EX16.28±81.48. The oil was also extracted using Soxley, and the yield was 37.6%. To estimate the antioxidant activity, the activity was studied using free radical DPPH (the largest activity in inhibiting free radicals was in the methanolic extract g/ml, which was estimated at IC50 = 51.90 µg/ml, while the activity of the oil was estimated at IC50 = 41.62 ± 3.45 mg/ml.Arrapeseed oil napus Brassica, flavonoids, phenols, antioxidant activity.السلجم الزيتيMaster
