Process of Guanxinning for Injection purified with macroporous adsorption resin / 中成药

AIM:To study the purified factors of Guanxinning for Injection(Radix et Rhizoma salviae miltiorrhizae,Rhizoma Chuanxiong,etc). METHODS: The total of salvianolic acid B、protocatchuci aldehyde and ferulic acid were used to evaluate for the study of type of macroporous adsorption resin,sample volume,the ratio of diameter to height,pH value and sample consistency etc. RESULTS: pH value Guanxinning extract was adjusted to 3.0,through D101 resin finally reached the ratio of diameter to height 1∶2,4 times of water was applied to elution and then 3 times of 70% ethanol for re-elution and collected. CONCLUSION: These factors are approprite for purifying Guanxinning for Injection.
