摘　　要：研究了用液-液萃取和固相萃取两种方法同时分离饲料中克伦特罗和沙丁胺醇。液-液萃取法中,采用乙酸乙酯+正己烷+异丙醇混合溶剂,克伦特罗和沙丁胺醇萃取率分别可达85.20%、83.00%;固相萃取法中,采用Amberlite XAD-2大孔吸附树脂,效果较液-液萃取更好,萃取率为91.25%和86.10%。两种分离方法用于饲料中克伦特罗和沙丁胺醇的测定,结果满意。The methods are studied that simultaneous separation clenbuterol and saltbutamol in feed by liquid-liquid extraction and solid phase extraction. In liquid-liquid extraction ,extraction yield of CL is 85.20% and extraction yield of SA is 83.00% by using acetic ether、hexane and isopropanol mixed solvent extraction. In solid phase extraction, extraction yield of CL is 91.25% and extraction yield of SA is 86.10% by Amberlite XAD-2 resin. The result is satisfaction determining CL and SA in feed by the two methods.
