TOTAL PHENOLS AND
ANTIOXIDANT ACTIVITIES OF LEAF AND STEM EXTRACTS FROM CORIANDER,
MINT AND PARSLEY GROWN IN SAUDI ARABIA
Abstract: Leaves and
stems of three different herbs from two different families were used to
extract phenolic compounds and the bioactivity of the extracts was
evaluated by using 1, 1-diphenyl-2-picrylhydrazyl or DPPH scavenging
ability or their antioxidant activities. Extract from leaves of mint,
which belongs to
Lamiaceae family
contained 1.24 mgGAE/100 mL of total phenolic compounds and 34.21%
antioxidant activity which were significantly higher than those in
extracts from coriander and parsley, both of which belong to Apiaceae
family. Extracts of leaves from these herbs showed more quantity of
total phenols and higher antioxidant activities than extracts from stem
parts, however both leaves and stems of these three herbs grown in Saudi
Arabia contained good quantities of total phenols (>1.02 mgGAE/100 mL)
and showed more than 18.3% free radical scavenging activity.
