Abstract:
AIM: To select optimum macroporous resin and adsorption conditions of crocin in Fructus gardeniae. METHODS: The content of crocin was determined by UV spectrophotometer with crocin Ⅰ as standard. Property of adsorption and desorption, adsorption dynamics and factors affecting the adsorption were investigated by static adsorption method. RESULTS: The macroporus resin of HPD series had the best performance; the adsorption quantily of HPD300,HPD450,HPD400、HPD600 was 100.60 、 91.15 , 100.95 、 72.27mg?g -1 , desorption efficiency 84.05% , 87.22% , 93.83% , 78.38% , time of adsorption equilibrium was 4,3,3,2 hours respectively; the purer the sample, the higher the adsorption quantity was; the adsorption quantity had no remarkable difference when pH was less than 8 and concentration of ethanol was less than 1.5% . CONCLUSION: HPD400 was the optimum macroporous resin; the appropriate adsorption conditions consisted of 15% alcoholic sedimentation after extraction in neutral solution.
