Abstract:
OBJECTIVE:To study the infuence of mixed decoction of Cortex Phellodendri,Radix Glycyrrhizae and Ramu?lus Loranthi on extraction rate of berberine.METHODS:The extraction amount from Cortex Phellodendri,Radix Glycyrrhizae and Ramulus Loranthi mixed decoction was determined by HPLC.The HPLC conditions were:Hypersil BDS C 18 column;mobile phase,acetonitrile-33mmol/L KH 2 PO 4 -triethylamine(20∶72∶0.1);detecting wavelength,345nm;column temperature25℃;flow fate1.0ml/min.RESULTS:Decoction of Cortex Phellodendri,Radix Glycyrrhizae and Ramulus Loranthi in combi?nation obviously decreased the extraction rate of berberine.CONCLUSION:Cortex Phellodendri should be extracted separately in formulating extract technic for preparations containing above-mentioned herbs.
