Abstract:
AIM:To establish a method for determing loganin and paeonol in Liuwei Dihuang Granules(Radix Rehmannial praeparata,Fructus Corni,Cortex Moutan,Rhizoma Dioscoreae,etc.).METHODS:Loganin was determined using acetonitrile-water(15∶85) as the mobile phase with UV detection at 236 nm,and paeonol was determined using methanol-water(70∶30) as the mobile phase with UV detection at 274 nm by HPLC with Diamonsil C_ 18(150 mm?4.6 mm,3 ?m) column.RESULTS:The linear ranges of loganin and paeonol were in the ranges of 2.34-234 ?g/mL(r=0.999 99),7.07-141.40 ?g/mL(r=0.999 6),respectively.The average recoveries of loganin and paeonol were 100.06%,95.75% with RSD of 3.10%,0.65%,respectively.CONCLUSION:This method is simple,accurate,reproducible and can be used for determining loganin and paeonol in Liuwei Dihuang Granules.
