Abstract: In this paper , we represent seven compounds [ tricin-7-O-β- D-glucoside (1 ) , naringenin-7-O-β- D-glucoside ( 2) , esculetin (3) , β-sitosterol (4) , 7α-hydroxyl-β-sitosterol (5) , 7α-methoxyl-β-sitosterol (6) and palmitic acid (7) ] .
All compounds were isolated from Ceratophyllum demersum L . which was collected from Lijang . We compare them with compounds isolated form the material collected from Kunming by TLC . The results show that the types of main secondary metabolite in Ceratophyllum demersum L . in Yunnan are similar .

Key words: Ceratophyllum demersum
