water methanol polarity
Methanol 100% is a good organic solvent to extract most of the compounds but it is not that polar compared to water. So combination of methanol-water will be good for most of the compounds from polar-non polar.Many papers are available on natural products,Burdick & Jackson solvents are arranged in order of increasing polarity index, a relative measure of the degree of interaction of the solvent with various polar test solutes. ... Methanol, 5.1. Pyridine, 5.3. 2-Methoxyethanol, 5.5 ... Water, 10.2
