Abstract:
The total phenolic and flavonoid contents and antioxidant potential of hot aqueous and
methanol extracts of whole plant of Enicostemma littorale Blume was investigated. The
percentage yield of hot aqueous extractive value (36.3%) was greater than the percentage yield
of hot methanol extractive value (21.8%) and the total phenolic and flavonoid contents in hot
methanol extract were found to be higher than in the hot aqueous extract of Enicostemma
littorale. Overall results of in-vitro antioxidant activity assays indicated that in comparison to
the standard trolox, Enicostemma littorale showed low antioxidant activity in DPPH, ABTS
and FRAP methods. Iron chelating activity not found at highest possible concentration of
both extracts. Although the total phenolic and flavonoids components were detected in the hot
methanol and aqueous extracts, these does not appear to be reported a comparison between the
observed in-vitro antioxidant activity and extractive values with total phenolic and flavonoids
contents of Enicostemma littorale.
