Considering other differences that in leaves of Podocarpus there are three resin ducts under vascular bundle of midrib, mesophyll cells are differentiated into palisade tissue and sponge tissue; in leaves of Nageia, there is only one resin duct under vascular bundle in each vein and no obvious differentiation in mesophyll cells, palisade tissue can be found on both sides, and sclereids can also be found in mesophyll tissue.
结合罗汉松属植物主脉维管束下面有3个树脂道,叶肉分化为栅栏组织和海绵组织,而竹柏属植物每个叶脉维管束下面有1个树脂道,叶肉分化不明显,两面都有栅栏组织,叶肉中还具有大量石细胞等特征,认为罗汉松属和竹柏属在叶脉、叶形态和结构方面存在明显差异,2个属分开是比较合理的。

The contents are mainly divided into three parts: The first part describes mechanism and metabolism rule of natural products and its classification ; The second part is about the growth and development of plants and their mutual relationship, natural biological active substances which are produced in the course of defending plant diseases and insect damages. The third part is not only the function and principle of medicine, anticancer and antioxygen activity of different kinds of natural products such as resin ,essential oil, high molecule, grease and so on but also their application. The fourth is security problem of Plant Natural Products. Through the lessons, we can correctly understand and use the relationship between plants and environment.
其课程分为13章,内容主要分为4大部分,一是阐述植物天然产物的发生机理和代谢规律,介绍相关主要植物种类,并对天然产物进行化学分类;二是讲述植物天然产物和自身生长发育之间的关系、天然产物如何影响植物之间的相互关系、以及植物如何利用天然生物活性物质抵御病虫害的威胁;三是详细描述了各种天然产物,如植物自身生长发育过程中所产生的活性物质、植物与其它生物之间的相互关系中所产生的生物活性物质、植物毒性物质、植物药理活性物质、植物抗生物质、植物树脂、植物精油、植物高分子、植物油脂、植物抗氧化活性成分等,并阐述它们的药理活性、抗癌性、抗氧化性等对人类健康起作用的的功能和原理;四是提出了植物天然产物的安全性问题,并介绍相关案例和介绍相关法规;在此基础上还专门讲述了树脂、精油、高分子、以及油脂类等天然产物的应用。

Based on relative literatures,this part has included five resesearch aspects as below.1 Fifteen compounds were isolated and purified by extraction,column chromatography,and their structures were determined on the basis of spectral analysis: acteoside(Ⅰ-1),isoacteoside(Ⅰ-2),crenatoside(Ⅰ-3),cistanoside F(Ⅰ-4),sinapoyl-4-O-β-D-glucoside(Ⅰ-5),adenosine(Ⅰ-6),β-siterol(Ⅰ-7),oleanic acid(Ⅰ-8), succinic acid(Ⅰ-9),caffeic acid(Ⅰ-10),protocatechuic aldehyde(Ⅰ-11),p-hydro xybenzyl alcohol(Ⅰ-12),β-daucosterol(Ⅰ-13),D-galacitol(Ⅰ-14),D-mannitol(Ⅰ-15).Ⅰ-4~15 were obtained from this plant for the first time,andⅠ-6,7,9,and 13 were isolated from Orobanche genus for the first time.2 The scavenging test of DPPH showed that most compounds have comparative antioxidant activity as L-ascorbic acid and part of them show better activity such as the O.coerulescens extract and phenylethanoid glycosides.Acteoside showed potent free radical scavenging effects with a median inhibition concentration of 25.6μg/ml.3 The anti-HBV activities of acteoside,isoacteoside and crenatoside were measured,and all of them showed suppressive activity on the expression of HBsAg and HBeAg in the HepG2.2.15 cell line.
本论文在文献调研基础上对紫花列当化学成分及生物活性进行了研究,并从免疫抗病毒角度探讨紫花列当中特征性成分类叶升麻苷的肝保护作用及其机制。1采用大孔树脂、硅胶和Sephadex LH-20等色谱技术对紫花列当进行系统的植物化学研究,从中分离得到19个化合物,利用UV和NMR等波谱手段及理化性质鉴定了其中的15个化合物,分别为类叶升麻苷(Ⅰ-1)、异类叶升麻苷(Ⅰ-2)、crenatoside(Ⅰ-3)、cistanoside F(Ⅰ-4)、sinapoyl-4-O-β-D-glucoside(Ⅰ-5)、腺苷(Ⅰ-6)、β-谷甾醇(Ⅰ-7)、齐墩果酸(Ⅰ-8)、琥珀酸(Ⅰ-9)、咖啡酸(Ⅰ-10)、原儿茶醛(Ⅰ-11)、对羟甲基苯甲酸(Ⅰ-12)、β-胡萝卜苷(Ⅰ-13)、D-半乳糖醇(Ⅰ-14)和甘露醇(Ⅰ-15除化合物Ⅰ-1、Ⅰ-2和Ⅰ-3外,其余化合物均为首次从该植物中分离得到。2)通过大孔树脂富集该药材有效部位苯乙醇总苷,并采用HPLC测得其所含特征性成分类叶升麻苷的含量可达80%以上。3DPPH自由基清除试验显示紫花列当提取物及其所含的苯乙醇苷类化合物均具有较好的抗氧化能力,其清除DPPH自由基能力接近于抗坏血酸。4采用卡介苗整体致敏、脂多糖离体攻击构建大鼠原代肝细胞免疫性损伤模型,在体外观察类叶升麻苷的保肝作用。
