摘要 建立了同时测定膏剂化妆品中1,3-二羟甲基-5,5-二甲基乙内酰脲(DMDMH)、1-羟甲基-5,5-二甲基乙内酰脲(1-MDMH)和5,5-二甲基乙内酰脲(DMH)的高效液相色谱法。采用Waters Atlantis T3 C18液相色谱柱(250 mm×4.6 mm,5μm);流动相为乙腈+0.1%甲酸溶液,流速1.0 m L/min,梯度洗脱;二极管阵列检测器,检测波长210 nm;柱温35℃。结果表明,DMDMH,1-MDMH和DMH质量浓度分别在17.86~595.20,17.65~588.39和18.05~601.67 mg/L范围内与相应的峰面积具有良好的线性关系,相关系数分别为0.999 5,0.999 7和0.999 8,空白样品加标回收率分别为82.6%~106.2%,98.4%~110.7%和98.6%~113.0%。 A HPLC method for simultaneous determination of 1,3- dihydroxylmethyl- 5,5- dimethylhydantoin( DMDMH),1- hydroxymethyl- 5,5- dimethylhydantoin( 1- MDMH) and 5,5- dimethylhydantoin( DMH) in cream type cosmetic products was established. The separation is performed on a Waters Atlantis T3C18column( 250 mm × 4. 6 mm,5 μm) with the mobile phase consisting of acetonitrile + 0. 1% formic acid solution at flow rate of 1. 0 m L / min for gradient elution. The detector is diode array type with wavelength of210 nm. The column temperature is set at 35 ℃. Results showed that the calibration curves display good linearity within the ranges of 17. 86- 595. 20,17. 65- 588. 39 and 18. 05- 601. 67 mg / L with correlation coefficient of 0. 999 5,0. 999 7 and 0. 999 8 for DMDMH,1- MDMH and DMH respectively. The recoveries are within ranges of 82. 6%- 106. 2%,98. 4%- 110. 7% and 98. 6%- 113. 0% respectively.
