Activated bleaching earth was tried as an adsorbent instead of silica gel for the thin-layer chromatography (TLC).
Good results were obtained in TLC as well as in silica gel from following matter :
1. The mixture of stearyl alcohol, cholesterol and liquid paraffin.
2. The mixture of sperm whale alcohols and cholesterol.
3. Unsaponifiables obtained from woolwax, beeswax, insect wax and sperm whale oil.
n-Hexane-ethyl ether (1/1, vol/vol) was better developer than other solvents tested.
