    Abstract:
    OBJECTIVE: To develop an HPLC method to determine the contents of danshensu, hydroxysafflor yellow A, rosmarinic acid, lithospermic acid, salvianolic acid B in the water extract of mixed Salviae Miltiorrhizae Radix et Rhizoma and Carthami Flos simultaneously. METHOD: The separation were carried out at 30 degrees C on a ZORBAX Eclipse Plus C18 column (4.6 mm x 100 mm, 1.8 microm) with formic acid-500 mmol x L(-1) ammonium formate-water solution (0.5:10:90) as mobile phase A and acetonitrile-formic acid solution (100: 0.5) as mobile phase B in gradient mode at a flow rate of 0.5 mL x min(-1). Detection wavelengths were 280 nm for danshensu, rosmarinic acid, lithospermic acid, salvianolic acid B, and 380 nm for hydroxysafflor yellow A. RESULT: The 5 components were separated well with a good linearity (R2 > 0.999 3) in the range of the test concentration. The average recoveries of danshensu, hydroxysafflor yellow A, rosmarinic acid, lithospermic acid, and salvianolic acid B were 99.1%, 102%, 102%, 98.5% and 101%, respectively. CONCLUSION: This method is simple, accurate, and repeatable.
