摘要: 实验探讨了大孔吸附树脂Diaion HP20富集纯化山茱萸总苷的工艺条件和山茱萸总苷的抑菌活性。结果表明,大孔吸附树脂Diaion HP20最优吸附条件为:上样液取自然pH值,盐离子浓度0.5mol/L、上样液浓度2.55mg/ml、上样量6BV。吸附完全后,用4BV去离子水以1.5ml/min的流速除去水溶性杂质,再用6BV30%乙醇解吸,可以较好地分离山茱萸总苷。通过抑菌实验,发现山茱萸总苷对金黄色葡萄球菌、绿脓杆菌、白菜软腐病菌、姜瘟病菌、柑桔溃疡病菌都有较明显的抑制效果。

Abstract: The separation technology with Diaion HP20 resin and antibacterial activity of glycosides from Cornus officinalis Sieb. et. Zucc. fruits were investigated in this study. The results indicated that optimal separation conditions with Diaion HP20 resin are:intrinsic pH value of extract of Cornus officinalis fruits,NaCl solution concentration 0.5 mol/L,original concentration of the extract 2.55 mg/ml and sample volume 6 BV. After being absorbed completely by macroporous resin HP-20,glycosides of Cornus officinalis were eluted with water(4 BV) and 30% ethanol(6 BV) in turn at 1.5 ml/min velocity of flow. The glycosides of Cornus officinalis have obviously antibacterial activity in vitro,against such pathogens as Staphy lococcusaureus,Pseudomonas aeruginosa,Erwinia carotovora var. carotovora,Ginger bacterial wilt and Xanthomonas citri.
