Solvent extraction may be carried out using Rotary evaporator

Greets!! Tou can use Colum chromatography, by using sovlent system start with highest nonpolar solvent then increase polarity gradually, by addition of methanol, like you can start 100% chloroform then start increase polarity by increase % of methanol as 5%,10%,20,30,40,50,,, untile the column silica be clear, each fraction should be collected and test its NMR and Mass spectroscopy, but first you should develop a good TLC plats can detects the diffrents spots of extract
