The developed method for diagnostics of molecular structure and composition of pharmaceutical preparations is presented by example of citramonum and aspirin. The method is based on fiber-optical recording of photoluminescence spectra excited by ultra-violet laser (266 nm). Difference photoluminescence spectra were calculated which allow one to establish the discrepancy in structure and composition of the preparations. The method can be used for quality control of a large class of the bioactive structures that are luminescing when exposed to ultraviolet emission.
