탐토료공업급탑랍단저산적제취급순화공예，병유정교시험학정료최우제취조건：제취시간3 h，제취온도50℃，료액비1∶15 g/mL，제취차수3차；규조토、활성백토화활성탄최가첨가량균위1.5％，탑랍단저산질량분수가체도80％이상。
The extraction and purification conditions of tara tannic acid were studied.Among the or-thogonal experiment,the optimum extraction conditions are as follows:extraction time 3h,extraction temper-ature 50℃,the solid -liquid ratio 1∶15,extraction three times.The optimum adding amount of diatomite, activated clay and activated carbon are 1.5%.The verification experiment showed that by adding diatomite, activated clay and activated carbon,tara tannic acid content can reach more than 80%,according with re-quirements of industrial tannic acid content.
