Phytochemical Screening Analysis
For phytochemical analysis, flavonoids
and hydrolysable tannins were found as
major constituents in ethanolic extract of
E. prostrata while flavonoids and phenolics
were found in fraction EP07. Similar results
were previously reported that triterpenoids,
flavonoids and phenolic acids were found
as major constituents in methanolic extract
of E. prostrata [29]. Tannins, flavonoids,
coumestans, saponin and alkaloids were
also presented in methanolic extract of the
plant, E. prostrata [30]. Thus, the presence of
flavonoids in E. prostrata was likely to be
responsible for the free radical scavenging
activity in this study.
