摘要: 采用正相高效液相色谱,建立了化妆品中α-,β-熊果苷的含量测定方法。采用S-Chiral A色谱柱(250 mm×4.6 mm,5 μm)和二极管阵列检测器,以V(正己烷)∶V(乙醇)=70∶30的混合溶液为流动相,流速为0.8 mL/min,检测波长为226 nm,柱温为30 ℃。α-,β-熊果苷的检出限(S/N=3)分别为1.5和3.6 ng,定量限(S/N=10)分别为1.6和6.3 ng,10~500 mg/L内,峰面积与质量浓度呈良好的线性关系,相关系数分别为1.000 0和0.999 0。高、中、低不同水平的加标回收率为99.61%~103.36%,RSD不大于0.80% (n=6)。该方法操作简便,准确度、灵敏度和稳定性高,可用于化妆品中α-,β-熊果苷的含量测定。

Abstract: An analysis method was established for determination of α-,β-arbutin in cosmetics by normal phase high performance liquid chromatography. The separation was performed on an S-Chiral A column (250 mm×4.6 mm,5 μm) with n-hexane-ethanol (volume ratio 70∶30) as the mobile phase at a flow rate of 0.8 mL/min. The detection wavelength was 226 nm. Operating temperature was 30 ℃. The limit of detection of α-,β-arbutin are 1.5 and 3.6 ng respectively,and the limit of quantification are 1.6 and 6.3 ng respectively. A good linear relationship is obtained between the peak area and the mass concentration of α-,β-arbutin in the range of 10~500 mg/L and the correlation coefficient are 1.000 0 and 0.999 0 respectively. The recoveries of α-,β-arbutin at different spiked level are 99.61%~103.36% with the relative standard deviations (RSD) no more than 0.80%.
