In this experiment root of Cichorium intybus L. as a raw material, hot water was used as solvent to optimize the conditions for maximum extraction of inulin from Cichorium intybus L. by orthogonal design and artificial neural network model. Results showed that the ratio of material and solvent 1 :8 (g/mL), extraction temperature 75℃, and time 2 h, under the condition of extraction once, extraction ratio of inulin reached to 33.29%.
