The main compounds identified by high performance liquid chromatography were gallic acid, (+)-catechin, (-)-epicatechin, the dimeric procyanidins B1 and B2, the trimeric procyanidin C1 and epicatechin gallate.

Oilseeds are crucial for the nutritional security of the global population. The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n-hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high …

Production Process for Sunflower Seed Oil. Expeller pressed sunflower oil and solvent extraction methods are two common production processing for sunflower oil. Using the pressing method typically results in an oil residue rate of around 7%, whereas solvent extraction can reduce the oil residue rate to about 1%.

Percent Oil Extraction Using Hexane. Table 2 shows that the percent oil extracted using hexane were ranged from 17.93 to 33.07 with the mean value of 27.43%, for different combination of the independnt variables viz., particle size, extraction temperature, and residence time. Tsaknis et al. (1999) studied the solvent extraction of oil from …

Solvent extraction is the most widely used method. The extraction of natural products progresses through the following stages: (1) the solvent penetrates into the solid matrix; (2) the solute dissolves in the solvents; (3) the solute is diffused out of the solid matrix; (4) the extracted solutes are collected.
