Introduction. Hippophae rhamnoides L., the common sea buckthorn, deciduous shrubs in the
family Elaeagnaceae. The plant is being used in different parts of the world for its nutritional and
medicinal properties.
Aim of the study. The present study focused on the antioxidant activity determination and total
phenolic content of leaves (fresh/dried) and fruits (fresh/dried) of Hippophae rhamnoides L.
Materials and methods. In vitro antioxidant activity of extracts was assayed by DPPH, ABTS,
and Iron chelating activity (ferrozine) tests. Total total phenolic content was determined by using
the Folin-Ciocalteu assay.
Results. In all assays, the leaves of H. rhamnoides L. showed higher value of antioxidant activity
(fresh: DPPH – IC50=28.88 μg/ml; ABTS – 28.79 μM TE/g dried weight; Iron chelating activity
– 33.40 %; dried: DPPH – IC50=25.67μg/ml; ABTS – 29.04 μM TE/g dried weight; Iron
chelating activity – 53.06 %) than fruit extracts (fresh: DPPH – IC50=357.97 μg/ml; ABTS –
16.44 μM TE/g dried weight; Iron chelating activity – none; dried: DPPH – IC50=689.52 μg/ml;
ABTS – 9.03 μM TE/g dried weight; Iron chelating activity – none). The total phenolic contents
in the examined leaves and fruits of H. rhamnoides extracts were 2.91 (died) – 4.57 (fresh) and
0.54 (fresh) – 2.30 (dried) mg GAE/g, respectively.
Conclusions. H. rhamnoides leaf extracts have shown considerable antioxidant properties. The
consumption of this may play a role in preventing several human diseases, which involve the
free radicals, such as cancer, cardiovascular disease, and premature aging. Thus, further
investigations on the in vivo antioxidant activity and other antioxidant mechanisms are
warranted. |
