Objective: To optimize separation and purification technology of iridoid glycosides from Lonicerae Japonicae Flos by macroporous resin. Method: The content of loganic acid
7-epi-loganin
sweroside and secoxyloganin was determined by UPLC
static adsorption-elution test was adopted to screen type of macroporous resin
separation and purification process conditions of iridoid glycoside were optimized by single factor tests. Result: H-103 macroporous resin was selected
optimum technology was:sample solution concentration of 100 g·L-1
adsorption flow rate of 2.0 BV·h-1
sample liquid volume of 2.5 BV
eluted by 2.5 BV of water and 3.0 BV of 30% ethanol at elution flow rate of 2.0 BV·h-1.Under these conditions
elution rate and purity of iridoid glycosides were 90.0% and 25.6%
respectively. Conclusion: Iridoid glycosides from Lonicerae Japonicae Flos are purified effectively with H-103 macroporous resin
