| description | In recent years, the illegal addition of male sexual function-regulating compounds in traditional Chinese medicine (TCM) has attracted widespread attention. These illegally added compounds may have specific pharmacological and toxic side effects, which can endanger lives when taken with other related therapeutic drugs. In 2009, National Medical Products Administration of China established a standard detection method for illegal sexual function-regulating compounds in TCM. However, this method has limits of long detection time, low qualitative accuracy, and narrow detection range, making it inadequate for regulatory requirements. In this study, a method of ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF MS) combined with UNIFI software was developed for detecting illegally added compounds used to treat premature ejaculation (PE) and erectile dysfunction (ED) in TCM. Sample preparation methods were selected according to different TCM formulations. Chromatographic separation was performed on an ACQUITY UPLC HSS T3 column (2.1 mm×100 mm, 1.8 μm). The mobile phase consisted of acetonitrile-0.1% formic acid solution with gradient elution at a column temperature of 30 ℃. Data acquisition was conducted in MSE mode under positive electrospray ionization with a mass scan range of m/z 50-1 200. A targeted screening database for illegal additives was constructed in UNIFI software based on chromatographic retention time, precise mass of parent ions and fragment ions of reference standards. Screening conditions were set according to EU SANTE/11312/2021 guidelines, and automated screening and analysis of detection results were achieved through the UNIFI software. Compared with the standard detection method, this method reduces the detection time from 160 min to 12 min, and expands the detection range from 11 ED treatment compounds to 31 compounds, including 11 new ED-treating compounds and 9 PE-treating compounds. The limits of detection are 0.25 to 15.00 mg/kg (or mg/L). In the detection of 20 batches of kidney-tonifying and yang-strengthening TCM samples, illegal additions are found in 7 batches, with 4 batches containing compounds beyond the scope of the standard detection method. This method has advantages of rapid detection, high accuracy, broad detection range, and flexible expansion capability, which can provide more robust technical support for regulatory oversight of illegal additions in TCM. |
