Abstract The presence of a sildenafil derivative, the thiosildenafil, in an herbal product has been evidenced first by HPTLC and later determined by isolation and analysis of spectroscopic data. The analyzed product is nowadays marketed as dietary supplement containing herbal extracts and claimed for male and female sexual improvement. This report is noteworthy since it is clear that adulterated materials can cause serious health problems if they are consumed as herbal "natural" products, generally considered deprived of toxicity by the consumers. The use of a simple and reliable method, based on HPTLC, to determine synthetic adulterations is reported in this paper.
