WebFurther, the antidiabetic effect of Lc-EAF in streptozotocin (STZ)-induced diabetic mice were demonstrated. Ethyl acetate, hexane, and methanol fractions of the L. cuneata showed … WebHexane is non-polar with its symmetrical structure. Ethyl acetate is polar because it has carbonyl bonds, and dipole moment does not cancel each. The different rates created a difference of polarity between mixtures. In mixture 80:20, there was more ethyl acetate than hexane; therefore, the polarity of the solvent.
