RESUMEN
The applicability of high-performance liquid chromatography with ultraviolet light (HPLC-UV) for the determination of the presence of statins in macromycetes of the genus Pleurotus was analyzed. The fungi were obtained by liquid-state fermentation (LSF) using unconventional sources of carbon as substrates and solid-state fermentation (SSF) employing agro industrial wastes. Five statins were used as standards: lovastatin and simvastatin in the lactone form (LOVL and SIML), their corresponding hydro-acidic forms (LOVH and SIMH) and pravastatin (PRA). The following measures were evaluated: the linearity, accuracy and precision, detection limit (DL) and quantification limit (QL). The results demonstrated HPLC-UV to be an effective tool for detecting the presence of statins in extracts of LSF and SSF products. Likewise, it was hypothesized that the strains that were used for the study do not produce statins. This finding highlights the importance of continuing to evaluate other strains of the same genus by using techniques such as HPLC to first separate sufficient quantities of the compounds that were detected using the standard technique but that did not match the retention time (tR) of any of the standards used.
