【Abstract】 <Abstrcat>Using phosphoric acid as the catalyst, the synthesis technics of bioactive oligosaccharide with glucose by solid phase reaction under microwave irradiations was studied. The optimum reaction conditions was that microwave power 800 W,microwave irradiation time 10 min, adding 30% water to initiate reaction, adding 10% heteropoly acid A as the catalyst, the yield ratio of product was 50.6%. The product was characterized with HPLC and included glucose 49.34%, maltose 10.03%, isomaltose 18.03%, maltotriose 5.40%, panose 10.13%, isomaltotriose (5.30%,) tetrasaccharide and pentasaccharides 1.61%.更多还原
