THE ANTIOXIDANT AND ANTICANCER ACTIVITIES OF STRAWBERRY SEEDLING (Fragaria X ananassa c .v. Sweet Charlie) EXTRACTS

Studies were conducted to evaluate the antioxidant and
anticancer activities of strawberry seedlings shoots extracts (SS) and
strawberry seedlings roots extracts (SR) using different solvent
systems. SS and SR extracts had high antioxidant activity % on
linoleic acid system, where butanol fraction (BUF) of SR had the most
antioxidant activity (IC 50=28.32 μg /ml) In comparison with BHT
(IC 50=31.5 μg/ml) and BHA (IC 50=33.75 μg /ml).
SS AND SR extract had high scavenging activity on di phenyl
picryl hydrazyl (DPPH) radical, where the highest scavenging activity
was observed in butanol fraction (BUF) of SS (93.55%) followed by
ethyl acetate fraction (EAF) of SS (93.16%), EAF of SR (93.08%) and
BUF of SR (92.79%) at concentration 25 μg /ml while ascorbic and
BHT had lower scavenging activity (90.30% and 90.80% respectively)
The observed data revealed a positive relationship between
antioxidant activity and the extracts content of total phenols and
flavonoids and also between reducing power value.
The obtained result showed that SS fractions had a higher anti
cancer activity than SR fractions where EAF of SS had the highest
anticancer activity (81.70%) while EAF of SR had (53.18 %) at
