New　method　for　rapid　and　quantitative　analysis　of　6-benzylaminopurine　(6-BA)　residues　in　sprout　beans　was　studied　by　using　FAST-SPE　and　portable　surface-enhanced　Raman　spectroscopy　(SERS).　With　homemade　sprout　bean　samples　as　blank　control,　6-BA　solutions　extracted　from　inserted-treatment　samples　showed　typical　characteristic　Raman　peaks　at　1　002　cm(-1)　tested　by　SERS,　and　normalized　1　002　cm(-1)　intensities　had　a　good　linear　relationship　with　gradient　concentrations　of　6-BA　insert-standard　solutions.　The　high　concentration　linear　range　was　0.5　similar　to　14　mu　g　.　mL(-1),　and　the　low　one　was　0.1　similar　to　2　mu　g　.　mL(-1).　The　quantitative　detection　limit　was　down　to　0.02　mg　.　kg(-1)　that　was　below　the　maximum　allowable　residues　(MAL)　of　0.2　mg　.　kg(-1)　in　related　National　Standard.　The　recoveries　were　82.3%similar　to　95.1%　and　the　RSD　was　below　5%.　This　method　with　portable　equipment　and　simple　pre-treatment　showed　good　reproducibility,　short　test　time-consuming　and　easy　operating,　and　thus　it　would　provide　efficient　and　sensitive　solutions　for　large-scale　on-site　and　rapid　detections.
