How do I characterize my ethanol and water extract?

10 June 2025 0 10K Report

I have two extracts of octopus ink- ethanol and water extract, I need to isolate compounds from the same. Can silica gel column chromatography be used? since both are polar solvent extracts will this work? Or using Sephadex LH-20 column is better? If I use silica gel column can I prepare silica gel with 70% ethanol because that will be my eluent?
