摘  要:
建立了测定蜂王浆中羟甲基糠醛含量的固相萃取-反相高效液相色谱法。蜂王浆样品用水溶解提取,提取液用亚铁氰化钾溶液和乙酸锌溶液沉降蛋白后,再用C18固相萃取小柱净化。羟甲基糠醛用甲醇从C18小柱上洗脱,氮吹浓缩至近干,残渣用流动相溶解,过0.45μm滤膜后,用高效液相色谱仪在285nm测定。本方法线性范围为0.1~20mg/L,线性相关系数R2=0.9993;在0.2~10mg/kg添加水平时,回收率在87.2%~93.1%之间,相对标准偏差为0.9%~3.4%,方法检出限为0.2mg/kg。

摘  要:
A reversed-phase high performance liquid chromatographic method was described for determination of HMF (hydroxymethylfurfural) in royal jelly. The sample was extracted with water and removed proteins using the zinc acetate and potassium ferrocyanide solutions. The sample extract was cleaned up by C18 SPE cartridge, while the HMF was eluted off via C18 SPE cartridge with methanol and evaporated to dryness on nitrogen dry evaporator, and residues were dissolved in mobile phase and passed through 0.45μm filters for determination by a liquid chromatography UV detection with the wavelength of 285 nm. The linear range of the method are 0.1~100 mg/L and the linear correlation coefficient is 0.9993. In the ranges of 0.2~10 mg/kg , the fortification recoveries are 87.2%~93.1%, the relative standard deviations are 0.9%~3.4%. The limit of detection for the method is 0.2 mg/kg.
