How is oil extracted from Jatropha seed collections from Ethiopia?

The present study focuses on the determination of oil contents of thirteen different jatropha seed collections from Ethiopia. The oil was extracted with a Soxhlet extractor using n-hexane which was selected out of four different solvents: diethyl ether, ethanol, n-heptane, and n-hexane. Cotton and thimble were used as filter for the extractions.

How much oil is extracted from seed collections from southern Ethiopia?

The average oil extracted from the seed collections from southern Ethiopia was calculated to be 40.43%. The smallest oil yield (30.66%) was obtained from Kako seed collection.

Which solvent is used to extract oil from plant seeds?

Different solvents can be used to extract oil from plant seeds. Hexane, petroleum ether, diethyl ether, ethanol, n-heptane, isopropanol, acetone, chloroform, methanol, and 1-butanol were some of the most commonly used and reported solvents for oil extraction [ 17, 20, 21 ].

Can hexane extract oil from Jatropha seeds?

Except a few researches on oil extraction using hexane and petroleum ether, no research has been reported on oil extraction from jatropha seeds from different parts of Ethiopia by drying the seeds at an appropriate temperature [ 25] and using different solvents.
