| Abstract: | The antioxidant and radical scavenging activities of common wild greens
used by the village people in Tiruvallur District, Tamil Nadu were evaluated.
Among the plants studied, the methanol extract of Euphorbia hirta Linn. was
found to be rich in polyphenol content and had a low IC50 value for
DPPH (78.33 µg) and hydroxyl radical scavenging (662.62 µg). It showed high
antioxidant activity. The methanol extract of Senna auriculata (Linn.) Roxb. syn. Cassia auriculata Linn. flowers
and Eclipta prostrata Linn., leaves
were also effective. The efficacies
of the other plants were in the following order: Cardiospermum helicacabum Linn.var. luridum Blume > Boerhavia
diffusa Linn. > Centella asiatica (Linn.) Urban > Cissus quadrangularis Linn. > Celosia argentea Linn. > Marsilea quadrifolia Linn. > Pisonia grandis R. Br. syn. P. alba Span. > Solanum trilobatum Linn.
These plants have been traditionally used by villagers without any noticeable
adverse effects. The present study has indicated that the isolation of some
specific compounds responsible for these activities might help in several
aspects of food chemistry. |
