Many plants contain antioxidant compounds where it protects
cells against the damaging effects of reactive oxygen species
(ROS) such as singlet oxygen, superoxide, peroxyl radicals,
hydroxyl radicals and peroxynitrite which results in oxidative
stress leading to cellular damage. Cell damage caused by ROS
appears to be a major contributor to aging and to degenerative
diseases of aging such as cancer, cardiovascular disease,
cataracts, immune system decline, and brain dysfunction. The
study was carried out to demonstrate the antioxidant property
in
Embelia ribes
seeds.
Embelia ribes
, commonly known as
Vayu
vilanga
, is a medicinally valuable, woody climber, a well-known
drug in
Ayurvedic system
.
E. ribes
is identified and recognized by
Medicinal Board, Government of India.
E. ribes
is one of the red
list plant mainly found in semi evergreen and deciduous forests at
an altitude of 400 to 1500 m of Northern Western Ghats of India,
Sri Lanka, China. The dried powdered seeds were subjected to
sequential extraction by solvents like acetone, petroleum ether,
water, methanol, and chloroform in increasing order of their
polarity. The phytochemical screening of seed extracts revealed
that the seeds were rich source of secondary metabolites. The
results of DPPH and ABTS assays for antioxidant activity showed
great free radical scavenging activity under low concentrations
for methanolic extracts. Upon quantification of methanol and
acetone extract, they showed the highest amount of flavonoid and
phenolic compounds, respectively. The presence of flavonoids
and phenolics are responsible for the antioxidant activity as they
are free radical scavengers
