| Abstract: | A method for determining methyl-p-hydroxybenzoate and propyl p-hydroxybenzoate in the talcum powder by HPLC was developed. Methanol was used as an extraction solvent in this study. The targets substance would pass through a 0.45 Ixm filter membrane to be detected by a diode-array detector. The target substance then went through RP-HPLC with water and methanol before being quantified by external standard method. At the addition level of 5.0-20.0 mg/kg, a recovery of 82.5%~89.2 % and coefficient of variation of 3.7%-6.2% was expected. |
