Abstract
Purpose: To evaluate the effect of boiling
on in vitro bioactivities potency of Balanites
aegyptiaca L. Delile (desert date) aqueous extract, a
juice used traditionally for cooking ready-to-eat millet
flour paste.
Methods: Desert date fruits (1.5 kg) were
soaked in water (1:2, fruit: water) for 24 h and sieved.
The extract was divided into two parts - fresh extract (Fext)
and boiled extract (Bext) which was obtained by boiling
a portion of Fext for 10 min. The extracts were tested
against the stomach cancer cell line SGC7901 and for
antioxidant activity by 1,1-diphenyl-2-icrylhydrazyl
DPPH, hydroxyl radical and ferric reducing power
methods.
Results: Both fresh extract (Fext) and
boiled extract (Bext) exhibited pronounced antioxidant
activity with DPPH values of 88.2 and 97.0 %,
respectively, at hydroxyl radical concentration of 5
mg/ml. The extract contained a significant amount of
vitamin C (42.3 and 38.9 mg/100 g for Fext and Bext,
respectively). Boiling had significant effect (p < 0.01)
on its antioxidant activity and also on its cytotoxic
effect (56 % and 44 % dead cells respectively for Bext
and Fext at respectively, at a concentration of 200 μg/ml).
Conclusion: It is concluded that B. aegyptiaca
aqueous extracts have remarkable cytotoxic activity
against stomach cancer cell SGC7901.
