摘　　要：HPLC分析了玉米秸杆微粉酶解液中5种单糖组成，主要包括阿拉伯糖、甘露糖、半乳糖、葡萄糖、果糖，其中以葡糖糖与果糖为主。结果表明：粒径大于1200目的玉米秸杆粉酶解液还原糖单糖组分与100～200目的相比，其含量明显高，阿拉伯糖、半乳糖、葡萄糖、甘露糖和果糖分别提高了48．38％、64．29％、37．63％、70．07％和22．34％。此外，在超微细秸杆粉的酶解液HPLC色谱图上出现三个新的未知响应峰，推测可能为岩藻糖、庶糖与纤维二糖。The compositions of five different monosaccharides in corn stalk enzymatic hydrolysate were analyzed by HPLC. They were arabinose, mannose, galactose, glucose and fructose, in which glucose and fructose were the main compositions. The results showed that the reducing sugar composition contents in corn stalk powder with a particle 〉 1 200 mesh was higher than that with a particle size 100 - 200 mesh. The content of arabinose, galactose, glucose, mannose and fructose in enzymatic hydrolysate with particle size of 〉 1 200 mesh increased 48.38% ,64.29% ,37.63% ,70.07% and 22.34% , respectively. addition, three new unknown response peaks occurred in the chromatograms, might be fucose, sucrose and cellobiose.
