Aqueous, ethanolic extracts and fractions
of E. prostrata extracts were investigated for
anti-free radical activity by DPPH assay.
Moreover, total phenolic contents and the
prevention of oxidative protein damage
ability by E. prostrata extracts were
determined. From the present finding
demonstrated that the partial purified
EP07 fraction of E. prostrata showed
effective antioxidant activity and total
phenolic content more than crude extract.
Moreover, crude ethanolic extract of this
plant could inhibit the oxidation of BSA
protein. In addition, flavonoids were
found as major constituents in the EP07
fraction. Further study on determination
of toxicity of the E. prostrata extracts
should be carried on in order to use the
plant extracts as antioxidant and dietary
supplement.
