Abstract:
AIM: To study the purification of Naomaitong Granules(Radix et Rhizoma rhei,Rhizoma chuanxiong,Radix Puerariae lobatae.etc) by macroporous absorption resin. METHODS: Naomaitong Granule was purificated by macroporous absorption resin AB-8.UV spectrothotometry was used to determine the contents of total anthraquinones,total ginsenosides,total alkaloids,and the content of puerarin was determined by HPLC.The technic of purification was optimized according to the content above. RESULTS: The optimized technological conditions consisted of eoncentranon of original sample 120 mg/mL,the diameter and height was in proportion of 1∶10,the ratio of maximum adsorption to resin volume was 1∶6,water elution was 2B multiple of resin volume,8B multiple of resin volume 50% alcohol was the elution. CONCLUSION: AB-8 macroporous absorption resin can be used to purify Naomaitong Granules.
