糖基

The monosaccharides in LBP-4 identified by GC were xylose , galactose , mannose , Rhamnose , glucose and arabinose with the molar ratio of 4. 45: 1. 20: 1. 0: 0.98: 0.90: 0.85. The content of calcium, magnesium, zinc and iron in LBP-4a were 127. 9070mg·g〓, 32. 3953mg·g〓, 0.3845mg·g〓 and 0.2930mg·g〓, respectively. The content of galacturnic acid in LBP-4a was 55. 45% while the content of protein is 3. 80%. According to IR spectra, it contains -COOH group,-NH- roup,-OH group,-NH〓 group and β-D-glucose. The backbone of sugar residues chain in LBP-4a were contained 1→6 indican bond according to periodate oxidation and the results of β-elimination reaction indicated that the chain of polysaccharides and protein were connected by O-linked chemical bond. The photograph of LBP-4a got by laser scanning confocal microscope and scanning electron microscope showed that the LBP-4a combined both with each other and with itself in its crystalloid. The crystalloid was flake and anisotropic.

由LBP-4a的红外光谱图知：LBP-4a中含有-COOH、-OH和-NH〓或-NH-基团，糖链中含有β-D-吡喃葡萄糖；高碘酸氧化实验知LBP-4a糖链中不具有连二羟基和连三羟基结构的单糖残基：具有连二羟基结构的单糖残基：具有连三羟基结构的单糖残基=57.0：16.2：1，六碳糖残基的连接中含有1→6连接的糖苷键；通过β消去反应证明LBP-4a中多糖链和氨基酸间为-O-型连接；由激光扫描共聚焦显微镜和扫描电镜对LBP-4a结晶观察结果推测：LBP-4a结晶中同时存在分子间和分子内结合的现象，LBP-4a分子相互结合时，并不是无规则的相互缠绕形成无规线团结构，而是形成片层结构，并且LBP-4a结晶可能具有各向异性的性质。

Monosaccharides are classified according to (1) the number of carbon atoms present in the molecule and (2) whether they contain an aldehyde or keto group, thus a monosaccharide containing six carbon atoms is called hexose; a monosaccharide containing an aldehyde group is called aldose; and one containing a keto is called a ketose.

单糖的分类按照（1）分子中碳原子的数目（2）是否含有一个醛基或酮基，因此一个单糖含有6个碳原子叫做己糖；一个单糖含有醛基叫醛糖；含有酮基叫酮糖。

The correlations of eleven floral and fruit quantitative traits of Liriodendron interspecific hybrids(L. chinense×L. tulipifera) and its parent species were analysized.The aglycone and glycoside of flavonoid and carotinoids of perianth segment in the three groups were studied qualitatively and quantatively by high performance liquid chromatography.The results were as followed: The aglycone such as cyanidin, 6-hydroxyflavone and trans-chalcone and the glycoside such as glucose, rhamnose and galactose were discovered in Liriodendron interspecific hybrids and Liriodendron chinense,carotinoids such as lycopene and β-carotene were also discovered.

Moreover, MeJA induced defense genes, such as pathogenesis-related proteins (PR2a), phenylalanine ammonia-lyase, BX9, and TPS. MeJA also increased DIMBOA and Vannillic acid content of leaves and roots significantly but leaf p－Hydroxybenzoic acid concentration was decreased significantly and Protocatechuric acid was produced in roots only.
