The temperature affects partition of dipotassium glycyrrhizinat but the effect is minor. On the same time pH has major impact on the partition of dipotassium glycyrrhizinat. The coefficient is eight times higher when pH reaches 2. The improved Diamond-Hsu model can be used to correlate the partition coefficient of dipotassium glycyrrhizinat in the system of water/ethanol/isobutanol. The result of Infrared and TG analysis indicate the extraction product has the same characteristic features with dipotassium glycyrrhizinat.
