HPLC Fingerprint of Fructus Aurantii Immaturus / 中草药

ABSTRACT

Objective To establish HPLC fingerprint for Fructus Aurantii Immaturus.Methods The HPLC method was used with Diamonsil-C18 column (250 mm?4.6 mm,5 ?m),and a mixture liquid of acetonitrile-0.01% NaH2PO4 as mobile phase in a gradient elution.The HPLC fingerprint for 36 batches of Fructus Aurantii Immaturus was studied on their similarity,cluster,and principal components analyses.The common HPLC fingerprint of Fructus Aurantii Immaturus was established,which was studied with principal components analyses.Results Under the selected spectrum condition,the 36 batches of Fructus Aurantii Immaturus were classified into two groups based on the result of similarity,cluster,and principal components analyses.Conclusion This method is reasonable and reliable to the quality control of Fructus Aurantii Immaturus.
