Providing reference for the component analysis and development of acid tea.the contents of water extract,polyphenols and free amino acid were determined according to the national standard method of food.Seven trace elements,such as Fe,Zn,Cr,Cu,Mn and Ni,were determined by flame atomic absorption spectrometry(FAAS) after wet digesting.The contents of moisture,water extracts,polyphenols,free amino acid,soluble sugar,chlorophyll and total flavonoids in acid tea were determined as 7.16%,49.13%,26.29%,0.88%,19.90%,0.054% and 6.56% respectively.The sequence of trace element content in acid tea was Mn,Cu,Cr,Fe,Zn from high to low.However,Ni was not found.The recovery rate of various experimental elements was 98.70%~101.80%,RSD is 0.04%~2.35%,with the accuracy and precision according to the requirements.Polyphenols and soluble sugar were higher;FAAS can be used in determination of metal element contents in acid tea.
