Differently, the ethanol-precipitates from HWE (HWE-EtOH ppt) were mainly composed of galactose (~38 mol%), followed by arabinose (28 mol%), glucose (~13 mol%), rhamnose (~13 mol%), mannose (~6 mol%), and fucose (~3 mol%).

不同地，HWE经乙醇沉淀物(HWE-EtOH ppt)之单糖组成以半乳糖(37.5 mol%)为主，其次为阿拉伯糖(28 mol%)、葡萄糖(~13 mol%)、鼠李糖(~13 mol%)、甘露糖(~6 mol%)、及岩藻糖(~3 mol%)。

By this reaction, an aldose is converted into another aldose and the corresponding ketose, and a ketose is converted into the corresponding two aldoses.

单糖的异构化涉及羰基和相邻近的羟基，通过这个反应，一种醛糖转化为另一种醛糖，和相对应的酮糖，一种酮糖转化为相对应的两种醛糖。

Acid concentration in hydrolysis, the temperature and the time were important factors influencing the measurement results of monosaccharide content.

葡聚糖的纯度一般由酸水解后的单糖含量表示，水解时酸的浓度、温度和时间是影响单糖含量测定结果的重要因素。

Finally, the corn silk soluble polysaccharides was preliminarily analyzed to be composed by rhamnose, arabinose and mannose, three monosaccharide, through the method of the gas chromatographic analysis.

然后，玉米须多糖用硫酸水解得到单糖，衍生后经GC检测，初步鉴定玉米须多糖是由葡萄糖、木糖及鼠李糖3种单糖组成。

The results indicated that GLP was a linear (1→3)β-D-Glcp main chain linkage. Its monosaccharide component was predominantly composed of D-Glc, and small amount of galactose, mannose, xylose and idose, residues of branches terminated with substituted at 1→6 by a small number of singleunit β-D-Glcp side-chains, it's also observed that the (1→3)-linked β-D-glucan contained a triple-helical conformation, which was composed of a repeating unit with a structure as below:.

结果表明：灵芝多糖含有三螺旋体构型，GC-MS分析灵芝多糖的主要单糖组分为葡萄糖，还有少量的半乳糖、甘露糖、木糖和艾杜糖，IR及1HNMR分析多糖为β-构型，HIO4氧化、Smith降解和甲基化分析表明：多糖主要为(1→3)糖苷键连接构型，并伴有少量的1→6位支链键连接的结构，灵芝多糖是由D-葡萄糖单元通过β-(1→3)糖苷键连接葡聚多糖，其主要构型特征为(1→3)β-D-线性连接的骨架结构。

Results showed that a small amount of monosaccharide,mainly glucose was presented in the unhydrolyzed aloe while mannose and glucose were predominantly presented in the hydrolyzed aloe.

结果表明：未经水解的芦荟中含有少量的单糖，主要为葡萄糖；水解后的单糖主要为甘露糖和葡萄糖。
