| Abstract: | In
the present study eleven different fruits and leaves of commonly used
vegetables in diet in Asian subcontinent have been evaluated for antioxidative
constituents and free radical scavenging activities. Fifty per cent ethanolic extracts of Abelmoschus esculentus (Linn.) Moench (fruits), Trigonella foenum-graecum Linn. (leaves), Spinacia
oleracea Linn. (leaves), Brassica
oleracea Linn. var. capitata and B. oleracea var. botrytis (leaves, inflorescence
and young stems), Coriandrum
sativum Linn. (seeds and leaves), Capsicum
annuum Linn. var. grossum
(Willd.) Sendt. (fruits), Cucurbita
maxima Duch. (fruits), Cyamopsis
tetragonoloba Linn. (fruits), Anethum
graveolens Linn. (fruits and seeds), Solanum
melongena Linn. (fruits)
were tested for the determination of free radical scavenging potentials and
quantification of antioxidant agents such as ascorbic acid and phenolic
compounds. Amongst the tested vegetables the sample of B. oleracea var. botrytis
has shown (67.2%) the highest 1, 1-Diphenyl-2-picryl hydrazine (DPPH radical)
scavenging potential while B. oleracea
var. capitata was found to be the
most effective (58.4%) inhibitor of lipid peroxidation. The extract of S. oleracea (43.9%) and S. melongena (32.8%) were found to be
effective in ferrous ion chelating abilities. The maximum amount (25.60mg/100g)
of vitamin-C was found in A. esculentus
while the amount of total phenolics was noted maximum (13.30 mg/g) in C. maxima. With some exceptions the
activity profiles of all other samples were found to be good to moderate. |
