ABSTRACT
A simple method based on solid liquid extraction with low-temperature partition (SLE-LTP) coupled with high performance liquid chromatography-mass spectrometry (HPLC-MS) was developed for the determination of 6-benzylaminopurine (6-BA) in edible mushrooms. The samples were extracted with acetonitrile followed by low-temperature partition at -30â for 4 h. The separation was performed on a Hitachi LaChrom C18 column (250 mm×4.6 mm, 5 µm) with 0.02 mol/L ammonium acetate (containing 0.1% (v/v) glacial acetic acid)-methanol (64, v/v) as the mobile phases with isocratic elution. The compound was detected in positive electrospray ionization mode, and quantified by external standard method. The results showed that the limit of detection (LOD, S/N>3) for the analyte was 0.006 mg/kg, and the limit of quantification (LOQ, S/N>10) was 0.02 mg/kg. The calibration curve showed good linear in the range of 0.05-2.0 mg/L, and the correlation coefficient (r2) was 1.0000. The spiked recoveries were between 81.3% and 93.7% with the relative standard deviations (RSDs, n=6) of 0.7%-2.4% at the spiked levels of 0.1 mg/kg and 0.5 mg/kg. The developed method is simple, reliable and can be applied for the accurate determination of 6-BA residue in edible mushrooms.
