Abstract:
AIM: To apply the solid phase extraction (SPE) on salvianolic acids in Radix Salvia Miltiorrhizae by means of high performance liquid chromatography with mass spectroscopic detector (HPLC MSn). METHODS: A C 18 solid phase column and negative ion electrospray ionization (ESI) mode were used by orthogonal design to optimize four factors which might affect recoveries of samples, which included vacuum tightness, sample size, amount of eluting agent and eluting power. RESULTS: The optimized results were as follows: vacuum tightness was 0.002?106 Pa, sample size was 0.75 mL, amount of eluting agent was 15mL and eluting power was 1.0mL?s -1 . CONCLUSION: The established method is simple, reliable and suitable for the usual quality control method of salviamolic acids in Radix Salvia Miltiorrhizae.
