本文建立了糌粑中苯甲酸、山梨酸、糖精钠高效液相色谱检测方法。样品经水溶解，超声波辅助提取后，样液经高速离心，上清液经滤膜过滤后，采用高效液相色谱法测定样品中的苯甲酸、山梨酸、糖精钠。结果表明：该方法测定糌粑中苯甲酸、山梨酸、糖精钠的回收率分别达到94.1%~102.3%、96.2%~107.8%、94.0%~106.3%，相对标准偏差均小于5%。该方法适用于糌粑中苯甲酸、山梨酸、糖精钠的测定。
本文建立瞭糌粑中苯甲痠、山梨痠、糖精鈉高效液相色譜檢測方法。樣品經水溶解，超聲波輔助提取後，樣液經高速離心，上清液經濾膜過濾後，採用高效液相色譜法測定樣品中的苯甲痠、山梨痠、糖精鈉。結果錶明：該方法測定糌粑中苯甲痠、山梨痠、糖精鈉的迴收率分彆達到94.1%~102.3%、96.2%~107.8%、94.0%~106.3%，相對標準偏差均小于5%。該方法適用于糌粑中苯甲痠、山梨痠、糖精鈉的測定。
