摘　　要：用大孔吸附树脂DiaionHP-20和SephadexLH-20对杜鹃花瓣中色素进行分离和纯化,获得高浓度的植源性荧光物质,并对荧光物质进行抑菌实验。结果表明:花瓣浸提液中的色素经SephadexLH-20分离纯化,可以清晰看到5种不同荧光区域,其中绿黄色荧光效果最为明显。抑菌试验显示,该荧光色素对双球菌生长有很好的抑制作用。Diaion HP-20 and Sephadex LH-20 were used to isolate and purify pigments from Rhododendron simsii,and a fluorescent pigment with high concentration was obtained from plant organs.Meanwhile,the antibacterial activity of this pigment was also evaluated.The results revealed that 5 different fluorescent regions in the petal extract from Sephadex LH-20 purification were observed.The strongest fluorescent region is a yellow-green region.In addiiton,this fluorescent pigment revealed an obvious inhibitory effect on the growth of Diplococcus.
