Confirmation of Vardenafil Derivative KD-027 in Food by LC-MS and NMR Technology Combined with Chemspider Database Search
A novel compound was screened out in 3 batches of food products by high resolution mass spectrometry,and the mass spectrometry data of the compound showed that it was a vardenafil derivative. NMR spectroscopic characterization demonstrated the evidence of coexisting
cis-trans
tautomerism of the compound,which resulted in the molecular structure of the compound difficult to identify. Subsequently,according to combining with molecular formula search of Chemspider database,3 vardenafil analogs were finally locked among 32 isomers. Further compared the data of the suspected compound with commercial standard,it was finally confirmed as vardenafil derivative KD-027. The results of quantitative analysis by ultra-high performance liquid chromatography-tandem mass spectrometry revealed that KD-027 was well regressed with the mass concentration,and correlation coefficient(

) was 0.999 6 in the range of 1.0-100 ng/mL. The limit of detection and limit of quantitation were 20 μg/kg and 50 μg/kg,respectively. An average recoveries of 86.2%-115% at low,medium and high spiked levels in the matrix of liquor,pressed candy and solid beverage were obtained,with relative standard deviations(RSDs) of 2.7%-7.3%. The method was used to detect actual samples,and KD-027 was detected in two batches of pressed candies and one batch of solid beverage,with content ranged of 482-2 707 mg/kg. This method could provide a technical reference for the efficient detection of exogenous illegal additives in food.
