Abstract
Purpose:
To determine the antioxidant and free radical scavenging
properties of the ethanol and aqueous extracts from
roots of Carissa carandas and
Pergularia daemia in various in vitro
systems.
Methods:
Reducing power, DPPH radical, superoxide radical, nitric
oxide radical and hydrogen peroxide radical scavenging
assays were carried out to evaluate the antioxidant
potential of the ethanol and aqueous extracts from roots
of C. carandas and P. daemia. Total
phenolic content and total flavonoids were also
evaluated.
Results: In the DPPH radical scavenging assay the IC50
values were 178.84 and 169.39 µg/ml for ethanol extract
of C. carandas and P. daemia respectively.
In the nitric oxide radical scavenging assay the ethanol
extract of P. daemia showed maximum percentage
inhibition (65.14±0.0115), while the aqueous extract of
P. daemia exhibited least percentage inhibition
(62.69±0.0461) on superoxide radical scavenging, when
compared with other extracts. The aqueous extract of
C. carandas and P. daemia exhibited 50%
scavenging activity at 208.07 and 243.09 µg/ml on H2O2
radical. The reducing power of the extracts increased
dose dependently. All the extracts exhibited significant
antioxidant (p < 0.01) activity.
Conclusion:
The extracts of the roots of C.
carandas and P. daemia possess antioxidant
properties and could serve as free radical inhibitors or
scavengers.
