Dear Alina,

A very precise investigation of the effects of temperature and contact time on extraction efficiency of sunflower cake was reported using hexane as solvent (Baümler ER et al., JAOCS 2010, 87, 1489). Extraction at 60°C during 30 min leads to a very high yield (99%) for triacylglycerols and tocopherols and to a reduced phospholipid extraction (66%).

Another method which can be exploited is AUTOMATIC SOXHLET EXTRACTION

The method described by Soxhlet in 1879 is the most commonly used example of a semi-continuous method applied to extraction of lipids from foods. According to the Soxhlet's procedure, oil and fat from solid material are extracted by repeated washing (percolation) with an organic solvent, usually hexane or petroleum ether, under reflux in a special glassware.

For more on this method, please see the following link:

Dear Alina, usually for plant seeds we utilised the Soxlet method with ethyl ether as solvent to obtain a crude lipid extract while when we performed a fat extraction for GC fatty acid determination we utilised a (3:2) mixture of hexan isopropanol. Francesco

Dear Alina,

We used the Soxhlet method for oil extraction from Moringa oliefera seed oil. You can try this method.

Please check the attached file.

Hoping this will be helpful for you.

Dear Sir Hi

there is two method for extracting oil from oleaginous seeds : chemical method using solvant (hexane) with soxhlet apparatus or mechanic method using press extractor

Good chance
