Abstract:

UPLC method was established for determination of 11 kinds of plant whitening ingredients in cosmetics. Samples were extracted by 50% methanol, then separated by Agilent Eclipse column(100 mm×2.1 mm, 1.8 μm)using methanol and the aqueous solution of 0.1% phosphoric acid as mobile phase with gradient elution. The detection wavelengths were 280 and 237 nm, and the column temperature was 30 ℃. All of the calibration curves show good linear relationship in the range of injection volume and all the correlation coefficients are above 0.999; the average recoveries of astringent, milk and facial mask are in the range of 98.57%~103.44%, 95.09%~112.43% and 92.90%~104.21% respectively, with RSD of 0.42%~2.96%, 0.98%~2.21% and 0.79%~2.67% respectively. The method shows good reproducibility and durability. It can be used for simultaneous determination of 11 kinds of plant whitening ingredients in cosmetics.
