Objective: To investigate application of micro-emulsion thin layer chromatography (ME-TLC) in separation and identification of flavonoids in Shujin Dingtong capsules and Su's Jiegu capsules. Method: Using microemulsion as developing agent in combination with polyamide film as the stationary phase
factors for microemulsion resolution
such as types and concentrations of surfactants
co-surfactants
the oil phase
impact of moisture and organic modifier were investigated by adjusting composition of each component in microemulsion system to find the best TLC conditions for separation and detection of flavonoids in Shujin Dingtong capsules and Su's Jiegu capsules. Result: Naringin in Shujin Dingtong capsules were separated and identified simultaneously with developing agent of micro-emulsion form-acetic acid (9: 1)
micro-emulsion was sodium dodecyl sulfate (SDS)-n-butyl alcohol-n-octane-H2O (3.4: 7.3: 2.0: 75.0).Hyperin in Su's Jiegu capsules was separated and identified simultaneously with developing agent of micro-emulsion form-acetic acid (9: 1)
micro-emulsion was SDS-n-butyl alcohol-n-heptane-H2O (2.7: 6.3: 1.0: 75.0).Compared with the organic developing solvent
separation effect of micro-emulsion was improved. Conclusion: METLC is a new and efficient method for separation and identification of flavonoids in Shujin Dingtong capsules and Su's Jiegu capsules.
