Hii.. I'm doing a riset with plant extract and I have got the pure compound from it.. I like to know the antioxidant activities from the crude extract and the compound. But, both of my samples don't soluble in methanol or ethanol.
Can I use Chloroform, acetone or Acetonitrile as the solvent instead of methanol since my samples are insoluble in methanol?
For information, I'm using alpha tocopherol as positive control.
