To perform TLC, then use Butanol: Acetic acid: Water (4:1:1).

Spry plate with NP-PEG or 5% KOH.

Mahdi Belguidoum

you must do first a liquid-liquid extraction with ethyl acetate and butanol

Vinesh Kumar

The brief steps are:

Conduct preliminary analysis using laboratory chemical test methods. Then run TLC to know the type of fractions. After that Column Chromatography with HPLC, after isolated pure fraction run FT-IR, LC-MS, HNMR, CNMR for structure elucidation. You can read my papers too.
