Determination of total anthraquinones in Xiaofan lotion by HPLC method / 药学实践杂志

ABSTRACT

Objective To develop a method for the determination of total anthraquinones in Xiaofan lotion by HPLC.Methods Rhubarb anthraquinones were simultaneously separated and assayed on a Kromasil C18 column(250 mm×4.6 mm,5 μm) with the mobile phase of 0.1％phosphoric acid-methanol (15∶85) at 30 ℃.The detection wavelength was 207 nm.Results The linear relationship is good for Aloe-emodin and other five standard ingredients.The average recovery was 99.45％, RSD 1.68％.Conclusion The method is simple, rapid and accurate.It is suitable for determination of total anthraquinones in Xiaofan lotion.
