Eleven
major volatile
compounds were found in the
dichloromethane extracts of both
male and female G. c. Reticulata
Octane
5.6
3,5Androstadien17-one
8.1
Consisted
of an alkane (octane),
four aldehydes (benzaldehyde,
heptanal, octanal, and nonanal),
a phenol (p-cresol), two alkaloids
(indole and 3-methylindole), two
carboxylic acids (tetradecanoic
and hex- adecanoic acids), and a
steroid (3,5-androstadien-17one).

levels of p-cresol in giraffe
hair are sufficient to repel some
ticks.

5. What can be done by this property?
Such kind of volatile nanoparticals or nanounits can be filled
in jar which will help us repelling insects, microorganisms,
and ticks. It is easy to make and will help protect people from
various diseases such as lime disease and malaria.
The reticulated giraffe might inspire innovation
in paint manufactures to protect the coat and
finishes. This discovery will also takeaway insects
from your house.

6. IS IT FEASIBLE and SUISTAINABLE ???
Idea is sustainable because all of the ingredients in it are nontoxic and fairly common.
From studying the giraffe’s hair we can watch the process of
how the chemicals are made and mix together. After that, it is a
simple matter of making an artificial version.

7. Compound
As mentioned in earlier discussion we
know composition of all compounds so
we only require knowledge of
temperature ,pressure conditions…
For this ,we have to study the reaction
conditions in natural synthesis of that
scent.
