“…Therefore, a simple and rapid method to determine these three components simultaneously is highly desired for controlling drugs quantity validly. So far, several methods such as colorimetric method [12], ultraviolet spectrophotometric method [13], thin layer chromatography (TLC) [14], high-performance liquid chromatography (HPLC) [15][16][17], RP-HPLC [18,19], and highperformance capillary electrophoresis (HPCE) [20][21][22][23], MEKC [24] have been reported for the determination of water-soluble components in Salvia miltiorrhiza Bunge or in pharmaceutical preparations. Nevertheless, the first two methods were usually interfered by other compounds, TLC lacked quantitative precision, while HPLC appeared to be efficient and time-consuming; most of the CE methods only focused on one or two compounds of water-soluble constituents in Danshen.…”
