3. INTRODUCTION
Background of the Study
Plant oils:
useful in health, food applications and in
the industrial world

4. great demand of
plant oils, few
sources available
Necessary to find
alternative sources
of oils

5. Related plants found to have oils used in food
and industrial applications
Sterculia striata Sterculia foetida

6. What’s new in this study?

25. CONCLUSION
Sterculia sp.(seeds) can be a source
of plant oil. This type of oil can be
used in many commercial
applications.

26. RECOMMENDATION
• more comparisons with other types of
oil
• subject Sterculia sp. to higher
pressures and to study further the
fatty acids
• Other chemical analysis
