The antioxidant activity (AOA) measured by auto oxidation of
ß-carotene and linoleic acid coupled reaction varied from 15.3%
(CHF-CA-4) to 60.7% (CHF-CA-21) in extracts of different genotypes
under the present investigation. Zhang and Hamauzu (2003) examined antioxidant activity using ß-carotene/linoleic acid assay in
different colored bell peppers (C. annuum L.) and reported that
the phenolic extracts of green pepper (13.8%) had highest activity
followed by red (8.6%) and yellow peppers (8.1%).
