Chemical structure
Class of natural product
Market preparations
Isolation of the natural product: Fresh plant from leave or root of citrus
Insect-damaged and fungus-infested roots and leaves
Were removed
Dried in the Laboratory at room temperature until they broke easily by hand
Extracted Successively with hexane, chloroform, ethyl acetate and methanol
Under vacuum on rotatory
evaporator below 50°C
Extract was then evaporated and yield a brownish mass
A well-stirred suspension of silica gel in Petroleum ether at 60°C–80°C was poured into a column
When the absorbent was well settled, the excess of petrol-ether was allowed to pass through the column. The slurry was passed through the silica gel in petrol-ether and was digested to well stirred column. The column was successively eluted with hexane, chloroform, methanol, and their mixtures of increasing polarity.

Side effects
Contraindications Take care that Naringenin can interact with a quantity of pharmaceutical drugs, changing and influencing their blood level. These include
Statins thatare used for cholesterol control antiviral agents used to treat HIV/AIDS
anti-anxiety drugs
calcium channel blockers that are used to treat high blood pressure
non-sedating antihistamines such as Hismanal (astemizole)
immunosuppressive drugs used to prevent rejection of transplanted tissues organ.
3. Class of natural product
Naringenin is
colourless
and better.
Its class is
flavonoid that
belongs to
the flavanone
family.
they are
mainly found
in tomatoes
and citrus
fruits skin.
It have
potent anti-
oxidant and
anti-
inflammatory
activities.

6. Isolation of the natural product
A well-stirred suspension of silica gel in Petroleum ether at 60°C–80°C was poured
into a column
• When the absorbent was well settled, the excess of petrol-ether was allowed to
pass through the column. The slurry was passed through the silica gel in petrol-
ether and was digested to well stirred column. The column was successively
eluted with hexane, chloroform, methanol, and their mixtures of increasing
polarity.

7. Pharmacological actions & Mechanism of actions:
Inhibitory effect
Atherosclerosis
In Diabetes
Heart beneficence
Antioxidant
Inhibition of breast cancer
8. Qualitative Estimation
By HPLC with empower v.2 software for data collection and analysis.
The extract of naringenin is
weighted, mixed with the mobile
phase.
then directly injected into HPLC
system by an amount of 20 µL.
Data were reported as mean of ±
standard deviation.
by comparing the retention time
of the tested compound with the
pure standard compound of
naringenin, identification was
performed
9. Quantitative Estimation
- NP-HPTLC
- in NP-HPTLC plates in which 6mm wide and 8mm apart were the
band size of each track.
- on HPTLC plates, the samples were applied.
10. Quantitative Estimation
- In pre-saturated twin-through chamber, the plates were developed at room
temperature and 60 ± 5 % humidity using toluene, formic acid and ethyl acetate.
- Then at 360 and 270 nm absorbance, the dried and developed plates were
quantitatively analyzed.
12. Contraindications
• Statins thatare used for cholesterol control antiviral agents used
to treat HIV/AIDS
• anti-anxiety drugs
• calcium channel blockers that are used to treat high blood
pressure
• non-sedating antihistamines such as Hismanal (astemizole)
• immunosuppressive drugs used to prevent rejection of
transplanted tissues organ.
