| Abstract: | Objective] The study was to provide theoretical basis for further study and development and application of Porphyra tenera Kjellm.in coastal wetland.Method] With P.tenera in coastal wetland as material,the fresh frond was dried and grinded as sample.The content of amino acids,Vc and trace element in the sample was determined.Result] 15 kinds of free amino acids and 16 kinds of hydrolysis amino acids in the sample were detected out.The essential amino acids accounted for 24.35% of total free amino acids and that made up 39.81% of total hydrolysis amino acids.The species of vitamin and trace element were more and their content was high.In each 100 g sample,the content of Vc was 17.2 mg,and that of VE was 4.08 mg.Among trace elements,the content of Na was the highest,up to 356.7 mg per 100 g sample,the following was Ca,Mg and K,and the content of Pb and Cu was much lower than that of index value.Conclusion] There were abundant of amino acids,vitamins and trace elements in P.tenera of coastal beach,and it was worthy of further study,development and utilization. |
