Abstract

Abstract: 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.

Key words: Rhododendron simsii, fluorescent pigment, antibacterial effect
