Method for detecting asiaticoside and madecassoside in cosmetics

A method for detecting asiaticoside and madecassoside in cosmetics, comprising:

• step 1, preparing a reference solution and standard working solutions;
• step 2, preparing a test sample solution;
• and
• step 3, detecting the asiaticoside and the madecassoside by high performance liquid chromatography (HPLC), and analyzing detection results,
• wherein the HPLC is conducted under the following conditions:
• in a chromatographic column, octadecylsilane chemically bonded silica is used as a packing;
• the chromatographic column is at a column temperature of 30-40° C.;
• a mobile phase is a mixture of methanol, acetonitrile and water, and a volume ratio of the methanol, the acetonitrile and the water is in a range of 1.5-3.0:1.0-2.5:6;
• and
• the mobile phase has a flow rate of 0.5-1.5 mL/min.
