Embodiment

[0042] (1) Dry the bagasse xylan in a vacuum drying oven at 60° C. to a constant weight to obtain dry basis bagasse xylan.

[0043] (2) Weigh 16g of ferulic acid into a 250mL four-neck flask, add 22mL of analytically pure acetic anhydride and 13mL of analytically pure pyridine therein, and react at 4-30°C for 8 hours.

[0044] (3) Pour the material obtained in step (2) into a beaker, and add 20 mL of hydrochloric acid solution with a mass fraction of 30% to it under stirring with a glass rod until a white precipitate precipitates out in the beaker. After standing for 25 minutes, pour the supernatant into a recovery bottle.

[0045] (4) The white precipitate obtained in step (3) was washed three times with 20 mL of distilled water, and then sent to a constant temperature drying oven at 50° C. to dry to constant weight to obtain acetyl ferulic acid.

[0046] (5) Weigh 8g of acetylferulic acid obtained in step (4) and add it to a 250mL four-necked flask, and add 40mL of analytic...

Abstract

The invention discloses a preparation method of active bagasse xylan ferulate-g-LME / AA / AM. Firstly, bagasse xylan ferulate was synthesized with bagasse xylan as raw material and ferulic acid as esterification agent; Under the action of methylenebisacrylamide solution and initiator ammonium persulfate solution, it is further contacted with maleic acid-6-L ascorbic acid monoester (LME), acrylic acid (AA), acrylamide (AM) mixed monomer branch, to obtain a bioactive bagasse xylan ferulate-g-LME / AA / BA compound denatured derivative. Compared with sucrose xylan ferulic acid ester, the target product obtained in the present invention has greatly improved biological activity and greatly improved stability, and has a certain application prospect in the utilization of anticancer activity.

Description

technical field [0001] The invention relates to a preparation method of bioactive bagasse xylan ferulic acid ester-g-LME / AA / AM. Background technique [0002] In recent years, with the increase of cancer cases and the absence of truly effective drugs or vaccines, exploring and developing new, cheap, safe and efficient anti-cancer agents has become a new field that needs to be expanded urgently. Studies have shown that extracting anticancer active substances from natural products will be an effective development direction for the development of new anticancer agents. As one of the natural products with high biological activity, bagasse xylan is not only rich in content, but also degradable , anti-cancer, anti-oxidation, anti-inflammation, lowering blood pressure, immune regulation and other biological functions. Due to the defects of xylan itself, the modification of xylan by esterification and graft copolymerization can effectively change its molecular space structure to fur...
