| Abstract: | The extraction and purification conditions of tara tannic acid were studied. Among the orthogonal experiment,the optimum extraction conditions are as follows: extraction time 3h,extraction temperature 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 requirements of industrial tannic acid content. |
