OBJECTIVE：To study the purification technology of total tannins from Cibotium baronetz.METHODS：Tannins from C.baronetz was optimized by macroporous adsorptive resins.The types of macroporous adsorptive resins were screened with static adsorption capacity,static adsorption rate,static desorption quantity and static desorption rate as index.The purification technology was optimized with elution rate as index.RESULTS：The optimal purification technology was as follows：D101 macroporous adsorption resin,sample of 6 BV,flow rate of 1 BV/L,eluted by 3 BV water,collecting 10% and 20% ethanol eluent of 4 BV.The elution rate was 92.64% and the content of total tannins was 69.5%.CONCLUSION：The technology is reasonable and feasible,and it can be used for the purification technology of tannins from C.baronetz.
