WebFeb 24, 2014 · Both methods rely on chloroform and methanol to form a monophasic solvent system to extract and dissolve the lipids. A biphasic system is then produced in a purification step by the addition of water, leading to the separation of polar and non-polar compounds into an upper and lower phase respectively [10], [11]. WebExtraction without methanol. Under the exact same conditions, the use of methanol produced an HEM weight of 32.5 mg. Without methanol, the average weight of the hexane extractable material was 18.8 mg – a difference of 42% by weight! Seems like methanol plays a pretty important role in oil and grease extractions!
