Tea polysaccharide was abstracted with warm water, tea polysaccharide-Fe（Ⅲ）complex(TPC) was synthesized with tea polysaccharide and FeCl3 under the alkaline condition, The determination of Fe（Ⅲ） was conducted with the method of ferroin-Fe（Ⅱ） and atomic absorption spectrophometry. The results showed that: TPC is heavy brownish red and shapeless powder. It can dissolve in water, its solution is very stable at the pH from 3 to 12. Content of Fe（Ⅲ）in TPC is 20.71% by the method of ferroin- Fe（Ⅱ）and 20.13% by the method of atomic absorption.
