Identifying dietary alternatives for artifcial antioxidants capable of boosting antihemolytic and antioxidative defense has been
an important endeavor in improving human health. In the present study, we studied antihemolytic and antioxidative efects
of germosprout (i.e., the germ part along with sprouted stems plus roots) extract prepared from the pregerminated rice. Te
extract contained considerable amounts of antioxidant -carotene (414 ± 12 ng/g of extract) and phytochemicals such as total
polyphenols (12.0 ± 1.1 mg gallic acid equivalent/g of extract) and favonoids (11.0 ± 1.4 mg catechin equivalent/g of extract). Te
antioxidant potential of the extract was assessed by its DPPH- (2,2-diphenyl-1-picrylhydrazyl-) free radical scavenging activity
where we observed that germosprout extract had considerable antioxidative potentials. To evaluate antihemolytic efect of the
extract, freshly prepared erythrocytes were incubated with either peroxynitrite or Fenton’s reagent in the absence or presence of the
extract. We observed that erythrocytes pretreated with the extract exhibited reduced degree of in vitro hemolysis. To support the
proposition that germosprout extract could act as a good antioxidative agent, we also induced in vitro oxidative stress in erythrocyte
membranes and in the aorta, brain, heart, and liver tissue homogenates in the presence of the extract. As expected, germosprout
extract decreased oxidative stress almost to the same extent as that of vitamin E, as measured by lipid peroxide levels, in all the
mentioned tissues. We conclude that rice germosprout extract could be a good natural source of antioxidants to reduce oxidative
stress-induced hemolysis and damage of blood vessels and other tissues.
1. Introduction
Oxidative stress is essentially an imbalance between the
production of free radicals and the ability of the body to
counteract or detoxify their harmful efects through neu-
tralization by its own antioxidants [1, 2]. Oxidative stress
has been reported as the contributing factor in various dis-
eases such as infammatory diseases, ischemic heart diseases,
hypertension, hypercholesterolemia, stroke, various liver dis-
eases, hemochromatosis, neurodegenerative disorders, and
smoking-related diseases [3–8] and in the impairment of
erythrocyte functions including hemolysis [9]. An excess
of oxidative stress can lead to the oxidation of lipids and
proteins, which is associated with changes in their structures
and functions. Te recent growth in the knowledge of
free radicals and their detrimental efects on human health
is leading a medical revolution, promising a new era of
disease management [10–13]. Ironically, oxygen, an element
indispensable for life, under certain situations has deleterious
efects on the human body [12, 13]. Most of the potentially
harmful efects of oxygen are due to the formation of a
number of chemical compounds, known as reactive oxygen
species (ROS) or reactive nitrogen species (RNS), which have
a tendency to donate electron to other cellular components.
Recently, study of free radicals and antioxidants has provided
important understanding of disease mechanisms, thus paving
the way for their prevention and treatments [12, 13]. However,
synthetic antioxidants have been reported to be harmful
