| Abstract: | The basic chemical composition,amino acids and trace elements in leaves of Rhizophora stylosa were studied systematically in this paper.The percentage contents of moisture,ash,acid infusible ash,sulphide,crude fat and crude protein in leaves of Rhizophora stylosa were 69.18%,3.04%,0.094%,0.052%,7.75%,and 7.14% respectively;Seventeen kinds amino acids with total amount of 10.7mg/g were determined in leaves of Rhizophora stylosa,there were seven kinds of essential amino acids and accounting for 26% in total amino acid.Thirty one kinds of trace elements Al,B,Ba,Ca,Cr,Cu,Fe,K,Mg,Mn,Na,Ni,P,S,Si(soluble),Sr,Ti,Zn,As,Bi,Cd,Co,Ge,Hg,Mo,Pb,Sb,Se,Sn,V and W were analyzed,the contents of the eighteen kinds of elements Al,B,Ba,Ca,Cr,Cu,Fe,K,Mg,Mn,Na,Ni,P,S,Si,Sr,Ti and Zn in them were measured by ICP.There were plenty mineral elements which were essential for human beings. |
