Detection of illegally added drug components in health food

This standard specifies the liquid chromatography-mass spectrometry/mass spectrometry method for the determination of yohimbine, vardenafil, sildenafil, and tadanafil in health foods. This standard is applicable to the quantitative determination and confirmation of yohimbine, vardenafil, sildenafil, and tadanafil in tablets, capsules, and oral liquid health foods. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document. GB/T 6682 Analytical Laboratory Water Specifications and Test Methods 3 Principle Tablets, Capsule Samples: Yohimbine, Vardenafil, Sildenafil, and Tadanafil were extracted by methanol ultrasound, and the extract was diluted and filtered. The oral solution was directly diluted and filtered, and determined by liquid chromatography-mass spectrometry/mass spectrometry, and quantified by external standard method
