Methods:The water extract of dried rehmamnia root was subjected to HPLC, with catalpol as the assay standard of iridoid glycosides, so as to compare the purification effect of 101 fruit juice clarifier with that of Keyang 1 + 1 natural clarifier, as well as to compare the separation effect of alcohol with that of nonpolar macroreticular resin. Results: Iridoid glycosides in the water extract of dried rehmannia root could be effectively separated with nonpolar macroreticular resin after the glycosides had been purified with Keyang 1 + 1 natural clarifier. Conclusion: In industrial production, iridoid glycosides of dried rehmanniae root can be purified and separated with Keyang 1 + 1 natural clarifier in combination with nonpolar macroreticular resin.Read More
