The invention relates to fields of daily chemicals and pharmaceuticals industry, in particular to 6-amino-6-deoxyinulin as well as preparation and application thereof. In the 6-amino-6-deoxyinulin shown as a formula (I), the average value range of n is 10-35. The preparation comprises the steps of undergoing a helogenation reaction of inulin or undergoing esterification of inulin and sulfonyl chloride, respectively undergoing a reaction of the product obtained through the helogenation reaction of the inulin or the esterification and sodium azide or azido lithium at a temperature of 40-70 DEG C for 8-24 hours to obtain 6-azido-6-deoxyinulin, and reducing the 6-azido-6-deoxyinulin by utilizing triphenylphosphine or lithium aluminium hydride to obtain the 6-amino-6-deoxyinulin. In the invention, the 6-amino-6-deoxyinulin is obtained through an effective synthetic means; an inulin six-position easily-leaving group is obtained through utilizing halogen to substitute the primary hydroxyl ofthe inulin or through the esterification of inulin and sulfonyl chloride; and the 6-amino-6-deoxyinulin with high substitution is obtained through azido nucleophilic substitution and reduction. The 6-amino-6-deoxyinulin synthesized by the preparation method provided by the invention is simple in the synthetic step and easy to popularize; and the required equipment and raw materials are easy to get. The formula (I) is shown in the specification.
