Abstract :

This study was performed to investigate the possibility of functional materials of Rudbeckia laciniata through analyzing for nutritional components and antioxidant activity. General component of Rudbeckia laciniata is crude protein 22.36%, crude fat 4.38%, ash 12.17%, and total dietary fiber content 42.63% in Dry base. The highest content of minerals is potassium the following calcium, magnesium were found, in this result suggest Rudbeckia laciniata was alkaline material. The content of total phenolic compounds of Rudbeckia laciniata 70% EtOH extract is 161.29mg/g and the content of total flavonoid content is 40.41mg / g. ABTs radical scavenging activity of Rudbeckia laciniata 70% EtOH extract is 203.87 mg AA / 100g and DPPH radical scavenging activity of Rudbeckia laciniata 70% EtOH extract is 265.86�±5.795.
