So I use Gracilaria sp. for my research. I have tried to use 70% ethanol but I didnt get phytochem compounds. So I'm thinking to try again but I'm still confused,should i use 80% or 96%? I read that 80% is the ideal concentration but im still not sure. Do any of you have literature about this? Thank you
