Abstract:

A method for determination of the content and isomer distribution of a cosmetic raw material, i.e., hydroxypropyl tetrahydropyrantriol, was established by high performance liquid chromatography. Samples were extracted with water and then were separated by CAPCELL PAK ADME column and determined by differential refractive index detector. The column temperature was 35 ℃, the detector temperature was 40 ℃, and the flow rate was 1.0 mL/min. The results showed that, it had good linearity within the range of 0.1-2.0 mg/mL for hydroxypropyl tetrahydropyrantriol, with the correlation coefficient above 0.999 9. The recoveries were 99.3%-99.6%, with the relative standard deviations (n=3) lower than 0.76%. The limit of detection and the limit of quantitation were 0.03% and 0.10%, respectively. This method is simple, accurate and reproducible, which is suitable for both determination of the content and the isomer distribution of hydroxypropyl tetrahydropyrantriol.

Key words: hydroxypropyl tetrahydropyrantriol, high performance liquid chromatography, determination, isomer distribution
