INTRODUCTION
Background of the Study
Plant oils:
useful in health, food applications and in
the industrial world
great demand of
plant oils, few
sources available
Necessary to find
alternative sources
of oils
Related plants found to have oils used in food
and industrial applications
Sterculia striata Sterculia foetida

CONCLUSION
Sterculia sp.(seeds) can be a source
of plant oil. This type of oil can be
used in many commercial
applications.
RECOMMENDATION
• more comparisons with other types of
oil
• subject Sterculia sp. to higher
pressures and to study further...
