The invention discloses a preparation method of active bagasse xylan ferulate-g-LME/AA/AM. The preparation method includes: using bagasse xylan as the raw material and ferulic acid as the esterifying agent to synthesize bagasse xylan ferulate; using the bagasse xylan ferulate as the main body to further graft with maleic acid-6-L ascorbic acid monoester (LME), acrylic acid (AA) and acrylamide (AM) mixed monomers under the initiation action of a crosslinking agent N,N'-methylene bisacrylamide solution and an initiator ammonium persulfate solution to obtain the bagasse xylan ferulate-g-LME/AA/BA composite modified derivative with biological activity. The preparation method has the advantages that the biological activity of the prepared target product is increased greatly as compared with that of bagasse xylan ferulate, the stability of the product is increased greatly, and the product has certain application prospect in terms of antitumor activity application. 本发明公开了种活性蔗渣木聚糖阿魏酸酯-g-LME/AA/AM的制备方法。首先以蔗渣木聚糖为原料，阿魏酸
