LC-MS/MS法同时测定烟草中的16种游离氨基酸和6种Amadori化合物
Simultaneous determination of sixteen free amino acids and six Amadori products in tobacco by LC-MS/MS
摘要
Abstract
To develop a rapid method for simultaneous determining 16 free amino acids and 6 Amadori products (APs)in tobacco,a method based on liquid chromatography-tandem mass spectrometry(LC-MS/MS)was developed. After extracting with water,tobacco samples were separated on an Acclaim Explosive E2 column with the gradient elution mobile phase of methanol and 0.1%(V/V)formic acid aqueous solution. The mass spectrometry detection was carried out by means of electrospray ionization in positive mode(ESI +)with multiple reaction monitoring(MRM)method. The results showed that:1)The correlation coefficients(r2)were higher than 0.996 for the all calibration curves,the standard recoveries of the spiked samples ranged from 82.0% to 109.5%,the intra-day and the inter-day relative standard deviations(RSDs)were 0.6%-4.8%(n=6) and 1.3%-10.9%(n=6),respectively. 2)This method was simple,rapid,accurate,and suitable for the simultaneous determination of the free amino acids and APs in tobacco samples.关键词
