Rice bran , instead of using as animal feed, was stablized , studied from the phytochemical , pharmacological, toxicological and formulation points of view. It is developed to be used in bakery, nutraceutical, cosmoceutical preparations with soild scientific proof of evidence.

2. Diamonds are buried and ignored in deserts and mountains
for thousands of years….
Till picked up , polished and then they
glow forever Egyptian Rice Residues could be these
diamonds … !!!!
(Remember ,, Diamonds are JUST
CARBON
)
3. Paddy rice in Malaysia is roughly
more than 2.5 Million Tons;
giving more than 250 000MT
rice bran.
However due to non stabilization of Rice Bran
it is still discarded or used as animal feed despite its
high content of bioactive substances
It is here where an UNTOLD WEALTH of vitamins,
minerals and newly discovered disease fighting
antioxidants are found as well as Nutraceuticals for
alleviation of major illness symptoms (CVD, DM type II,
elevated Cholesterol levels, Anti inflammatory &
Hypertension).
4. Rice Bran is considered as one of the most nutritive ingredients of the rice crop,
where about 60% of the total nutritive value of rice itself resides.

These components can be obtained from other sources of nature separately, but Rice

Stabilized Rice Bran;
As bakery ingredient; US$ 250/ MT (20 %
replacement of wheat flour with better taste and more
nutritional data). This can utilize the majority of Rice
Bran in Malaysia
As Functional Food , US$ US$ 500 / MT ( For
elderly people, School children, lactating women,
athletics..etc)
9. NON Stabilized Rice Bran Extract
Polutry Feed; US$ 1 / liter

Chronic Toxicity Studies
Rice Bran extract showed no toxic effect on body weight,Result:
haematological parameters, liver & kidney functions, blood

:AMES Test
: Rice Bran extract showed no mutagenic activity on theResult
DNA.
Toxicological Activity; Prof. Dr. Ola A. Heikal GUC
17. Rats were rendered hypertensive by the intra-
peritoneal injection of L-NAME twice daily for 1 week.
By the end of that period, the animals showed a
significant rise in blood pressure.
Hypertensive rats were treated orally for 1-2 weeks
with Rice Bran Extract (RBEX).
Systolic blood pressure (SBP) and heart rate (HR) of
animals measured non-invasively.
20. Rice bran extract has definite potential to
lower blood pressure in animals with
established hypertension.
Antihypertensive effect is not associated with
appreciable changes in heart rate.
21. Standardized rice bran extract (SRB) tested on 2
models of inflammation:
Acute model: Carrageenan rat paw oedema
Chronic model: Adjuvant – induced arthritis
Samples of blood taken to determine:
a) myeloperoxidase: measure of antioxidant
activity
b) TNFα: mediator of inflammation.
c) IL – 10: anti-inflammatory mediator.
23. Rats rendered arthritic by subplantar injection of
Freund‘s complete adjuvant in right hind paw.
SRBE and diclofenac (reference standard drug)
given orally at same time and continued for 28 d.
Paw volume measured at regular intervals.
Blood samples collected for measuring mediators
(TNFα and IL-10) and myeloperoxidase (MPO)
activity.
29. Rice bran extract exerts potent anti-inflammatory
effects against acute and chronic processes in
vivo.
Effect associated with some anti-oxidant activity
and inhibition of inflammatory mediators (TNFα)
as well as enhancing antiinflammatory ones(IL-10)
In vivo effects supported by in vitro findings
30. Rice bran extract was incubated with neuro-
blastoma cells (SH-SY5Y) in vitro for 12 h.
Unesterified cholesterol levels measured.
Effect compared with pravastatin
31.
32. RBE was nearly as effective in lowering
unesterified cholesterol in vitro as pravastatin
which was taken as a representative of the
statin family known for its potent blood
cholesterol lowering effect.
Results encouraging: in vivo experiments in
progress
33. RBE incubated with mouse brain homogenates.
After incubation, homogenates cenrifuged, and
supernatants tested for lipid peroxidation by
measuring malondialdehyde (MDA) and
hydroxynonenal (HNE) levels
Effect compared with Trolox (Vit. E derivative)
known to have antioxidant activity.
34.
35. Acute and Subchronic Toxicity studies (28
days).
Acute results showed no toxic effects > 2g/Kg
Chronic testing 0.5g, 1g and 2g/kg/day orally
to male and female rats for 28 days.
Examination of effect on body weight,
haematological parameters, liver & kidney
functions, blood glucose, electrolytes, etc…
Organs examined histologically at end of study.
