The monosaccharide are made up of rhamnose, glucose, mannitose, galactose and xylose. It offers foundation for boosting biological activities by hydrolyzing saponins.

硅胶薄层层析证明刺嫩芽皂甙的单糖可能由鼠李糖、葡萄糖、甘露糖、半乳糖和木糖组成，这为酶水解提高刺嫩芽皂甙活性研究提供了依据。

GuangXi is the main section of sugar production in our country Sugar segregator is thekey equipment of sugar that influence the qualit\ of sugar. Therefore.

广西是全国重点产糖区，而糖分离机是糖厂生产成品糖的关键设备，其性能好坏直接影响成品糖的质量。

During these years (1997-2000) in the research area of annonaceous acetogenins 5 natural products and a number of chiral-pure analogs of annonaceous acetogenins have been synthesized using sugars as the starting materials. Their high activity and selectivity against cell line of colon tumor and a relationship between activity and configuration have been found too. In the respect of inhibitor of sialidase two new methodologies for the synthesis of chiral-pure 3-deoxy-ulosonic acid using hetero-Diels-Alder reaction or asymmetric propargylation as the key reaction were developed. On the topic of anti-leukemia marine natural product clavulactone a synthetic method based on the free radical cyclization and starting from sugar has been developed. In other title of PKC inhibited agent sphingosine a new synthetic route with SN2' as the key reaction has also been disclosed.

项目期间（1997-2000）在番荔枝内酯方面从糖出发合成了五个天然产物和一批手性纯的类似物，它们对肠癌细胞有很高的活性和选择性，并与构型有关；在唾液酸酶抑制剂方面发展了二类全新手性纯高碳糖的合成方法－杂原子D－A反应或丙炔基不对称加成为关键的反应；抗白血病海洋天然产物群柱虫内酯方面研究了由糖出发和自由基环化反应的合成方法；对PKC 起抑制作用的鞘氨醇方面也开创了新的合成途径－由糖出发并以SN2'反应为关键反应。

For amylase way to hydrolyze and produce glucose, Liguefaction temperature, PH value and saccharification time condition are strictly controlled, contents of disaccharide, trisaccharide and the Polysaccharides which are over tetrasaccharide can be reduced, and glucose quality can be improved.

淀粉酶法水解生产葡萄糖，严格控制好液化的温度、H值、化时间条件，可降低二糖三糖四糖以及四糖以上多糖的含量，提高葡萄糖的质量。

The sugar chains are usually trisaccharide or tetrasaccharide, and the aglycones are classified into three groups, i.e., solanidane, spirosolane, and other steroidal derivatives.

糖苷生物碱是主要分布于茄科和百合科植物中的糖苷类次级代谢产物，糖链通常由3或4个单糖组成，苷元通常为三类甾体生物碱：茄次碱烷、螺旋甾碱烷和其他甾体衍生物。

Compound 9 is glycosylated in the presence of TMSOTf with rhamose-derived trichloroacetimidates to provide target trisaccharide Saponin 1, oleanolic acid 3-yl-2,4-di-O-a-L-rhamnopyranosyl -p-D-glucopyranosideCoumpond 18 is prepared with oleanic acid and Bromide 11 through phase-thansfer catalysis glycosylation manner.

三糖皂苷Saponin 1是以葡萄糖齐墩果酸皂苷为起始原料，用BBTZ(1-苯甲酰苯并噻唑)选择性保护葡萄糖3′，6′-羟基得到化合物9，然后以化合物9为糖基受体，进行一步糖苷化可以在化合物9的2′，4′-羟基上同时引入两分子鼠李糖，最后脱掉所有的保护基得到目标化合物Saponin1。

The results showed that depending relatively largely on temperature, the solubility of xylitol decreased with adding ethanol and increased with adding impurities such as sorbitol or adonitol.

结果表明，木糖醇属于溶解度温度系数较大的一类物质；乙醇的加入可降低木糖醇的溶解度；而阿东糖醇、山梨醇等杂质会适当增大木糖醇的溶解度。

The loading process of trehalose has no effect on apoptosis of platelets. The efficacy of trehalose plus phosphate in suppressing apoptosis of platelets during cryopreservation is superior to that of only trehalose. Compared to 6% DMSO and 2% DMSO plus TS, trehalose plus phosphate can retain the same platelet count, superior hypotonic shock response and platelet aggregatory reaction to ADP, and lower apoptosis rate of platelets. Platelets cryopreserved with trehalose plus phosphate can retain intact ultrastructure.

结论血小板负载海藻糖的过程不会促进血小板的凋亡；海藻糖保存血小板时，联合应用磷酸盐在抑制血小板凋亡方面的效果优于单独应用海藻糖；海藻糖联合磷酸盐冻存血小板的长期效果较稳定，其维持血小板回收率的效果与6%DMSO及2% DMSO联合TS相同，维持血小板低渗休克反应、聚集功能及抑制血小板凋亡的效果优于6%DMSO及2%DMSO联合TS，并能较好地维持血小板的超微结构。

The content of tri-/tetra- antennary complex type N-glycans was decreased and the biantennary complex type N-glycan was increased on the surface of HL-60 cells by the treatment of ATRA or PMA, but the content of high-mannose type/hybrid type N-glycan was increased by these treatments, the change was just opposite to that of SMMC 7721 cells.

ATRA和PMA也均使HL-60细胞表面三/四天线N-糖链减少和二天线N-糖链增加，但却使高甘露糖型/杂合型N-糖链增加。
