Abstract:
Objective To investigate the chemical constituents of Ulva fasciata and identify the material base of the efficacy.Methods The constituents of Ulva fasciata were separated and purified on chromatography of silicon gel,and then their structures were identified based on their physical and chemical nature and the specula.DPPH method was used to evaluate free radical scavenging activity of the compounds.Results Five compounds were isolated from Ulva fasciata and identified as 5-hydroxy-3,6,7,3',4'-pentamethoxyflavone,5-hydroxy-6,7,3',4'-tetramethoxyflavone,2,5-keto-pyrrolepiperazidine,p-hydroxybenzcic acid,succinic acid.Conclusions All the compounds were isolated from Ulva fasciata for the first time,of which compound 1 and 2 showed relatively strong antioxidant activity.
