Separation of some water-soluble vitamins is done by thin layer chromatography on heulandite, a natural zeolite (45 \(\mu\)), as an absorbent. The separation was affected within the distance of 5 cm by ascending tic technique at optimised conditions using dimethyl formamide. The heulandite does not require a binder and was found to be a good adsorbent, comparable and some­times better than silica gel G.
