Abstract:
Objective:Eighteen inorganic elements were measured from the rhizoma and fibrous root of Polygonatum Cyrtonema Hua. The contents of K, Fe,Mg,Ba,Cu,Mn and Bi of them in rhizoma were higher than that of fibrous root, where as the contents of Na,Al,Ca,Ge,P,Zn and Sr elements in rhizoma were lowere than that of fibrous. Both contained As,Hg,Pb and Cd elements. In the meantime, 16 mino acid were determined. The total content of them was 8.92% for rhizoma and 9.61% for fibrous. Cystine, cysteine, tryptophan and ornithine couldn't be detected.
