[Method] HP-20 and HP-SS macroporous resin were applied to separate and purify macranthoidin B and dipsacoside B from Flos Lonicerae. The extract of Flos Lonicerae was first loaded onto an HP-20 column to enrich saponins, which were then separated by an HP-SS macroporous resin column to get pure macranthoidin B and dipsacoside B.[Result] The optimal HP-20 purification conditions included： a concentration of sample liquid at 4.8 mg/ml, a sample volume of 2 BV, an adsorption flow rate at 1.5BV/h, an ethanol concentration for desorption at 60%, a desorption volume of 3 BV,and a desorption flow rate at 1.5 BV/h. Total saponins were then separated by an HP-SS macroporous resin column which was eluted sequentially by water, 20%ethanol, 30% ethanol, 40% ethanol and 50% ethanol. Two purified compounds were obtained in fractions eluted by 40% ethanol and 50% ethanol, respectively. The two compounds were identified as macranthoidin B and dipsacoside B by13 C and1H nuclear magnetic resonance spectroscopy. [Conclusion] The combination of HP-20 and HP-SS macroporous resin could efficiently separate macranthoidin B and dipsacoside B from Flos Lonicerae.展开更多
