Abstract

To perform proficiency test for determining anti-impotence drug-like compounds in food, interlaboratory test has been done. Targets were 6 such as sildenafil, tadalafil, vardenafil, homosildenafil, hydroxy-homosildenafil and pseudo-vardenafilI. Total 13 institutes were participated and all is in charging of food analysis. To do double blind test, the reference materials were made as 13 different ginseng drink samples and each sample had random 3 targets. By the official method for anti-impotence drug-like compounds in food code, sample was just diluted in water, extracted in organic solvents, determined by HPLC/UV and then confirmed by LC/MS. The analytical duration was 60 days after receiving sample. Ten out of 13 institutes were satisfied by evaluation of Z-score and RSZ according to the regulation for managing analytical quality assurance.
