Question

A study extracted rosemary with three different solvents, methanol, ethanol, and acetone. These extracts were then tested for their content of phenolic compounds. These extracts were found to have 150, 117, and 97 mg gallic acid equivalents/g extract. Why do you think that they contained different levels of phenolics, and why would it matter, if the ultimate goal is to use the rosemary extract to protect oils against lipid oxidation?
