摘要
研究了反相高效液相色谱法测定化妆品中熊果苷的含量。熊果苷浓度在 0~ 5 0 0mg/L范围内 ,浓度与峰面积呈良好的线性关系。对 5 .0× 10 -4 mol/L熊果苷标准溶液 9次平行测定 ,相对标准偏差为 0 .46 %。
The method of determining the concertration of arbutin in cosmetics was developed by RP HPLC.The good linear calibration curve was obtained for 0~500 mg/L.Nine times to parallel detemine its stadard solution(5.0×10 -4 mol/L),the RSD is 0.46%.
