Antioxidant Capacity of Phenolics from Canola Hulls as Affected by Different Solvents

摘要

Potential use of canola hulls as a source of natural antioxidants was explored. The antioxidant activity of 80-100% (v/v) methanol and 70-80% (v/v) acetone extracts of canola hulls in a P-carotene-linoleate model system was comparable to that displayed by butylated hydroxyanisole (BHA). The scavenging effect of the above extracts, at 40 βg/assay on (DPPH) radical, was over 95%.
