Micelle-mediated extraction of tanshinones from Salvia miltiorrhiza bunge with analysis by high-performance liquid chromatography

A new method for analysis of sunset yellow in food samples based on cloud point extraction prior to spectrophotometric determination

“…The solubilization of polar solutes also decreases owing to dehydration of the polyoxyethylene chains accompanied by coiling more tightly [20][21][22][23][24][25]. Surfactant molecules in water at concentrations above its critical micellar concentration (CMC) form micelles.…”

Determination of fifteen bioactive components in Radix et Rhizoma Salviae Miltiorrhizae by high‐performance liquid chromatography with ultraviolet and mass spectrometric detection

“…Previously, several methods have been established for the quality evaluation of RRSM, including TLC (Li et al, 1993), HPLC (Ma et al, 2006;Liu et al, 2006;Shi et al, 2004Shi et al, , 2005, HPCE (Chen et al, 2005), and LC-MS (Zhang et al, 2005). Unfortunately, the abovementioned methods could only employ a few phenolic acids or diterpenoids separately as chemical markers to evaluate the quality of RRSM, and few reports have dealt with both the hydrophilic and lipophilic bioactive compounds (Zhou et al, 2006).…”

Cloud point extraction-HPLC method for determination and pharmacokinetic study of flurbiprofen in rat plasma after oral and transdermal administration

“…Thus, Genapol X-080 was chosen as the CPE surfactant in this paper. Its critical micellar concentration (CMC) is 0.05 mmol/l (0.028%, w/v) and cloud point is 42 • C in pure water [37]. Fig.…”
