Quality Control of Punarnava is highly essential for obvious reasons. Available methods fail to ensure quality of Punarnava in a rapid, simple and economical way. A TLC method incorporating the above objectives has been developed using Chloroform: Ethyl acetate: methyl alcohol (4:4:2) / Chloroform: Methanol (85:15) as solvent system and as Alcoholic sulphuric acid (10 %) visualizing agent. This method seems to be reasonably good and refinements to fine tune the results are underway
