ABSTRACT
OBJECTIVE:To establish HPLC fmgerprints of Naodesheng solid dispersion capsules.METHODS:HPLC method was adopted.The determination was performed on Hyspersil ODS2 column with mobile phase consisted of acetonitrile-0.05％ phosphoric acid (gradient elution) at the flow rate of 1.0 mL/min.The detection wavelengths were 210 nm (puerarin),345 nm (hydroxfsaffior yellow A).The column temperature was 30 ℃,and sample size was 10 μL.Using puerarin and hydroxysaffior yellow A as reference,HPLC fingerprints of 10 batches of sample were determined.Similarity evaluation,common peak identification and chemical components confirmation were performed by using Similarity Evaluation System of TCM Chromatographic Fingerprints (2012 edition).RESULTS:There were 29 and 23 common peaks in HPLC fingerprints of 10 batches of samples at 210 nm and 345 nm,respectively.The similarity was higher than 0.90.The medicinal material attribute of common peaks were Panax notoginseng,Ligusticum chuanxiong,Carthamus tinctorius,Pueraia lobata and Crataegus pinnatifida.Moreover,7 chemical components were identified at 210,345 nm,respectively.CONCLUSIONS:Established HPLC fingerprints can provide reference for identification and quality evaluation of Naodesheng solid dispersion capsules.
