The diverse types of tracheary elements and perforation plates in secondary xylem of A. asiatica show that previous knowledge about the tracheary elements and perforation plates in secondary xylem of A. asiatica is not complete and thus any inferences about the aboriginality and evolution of a taxon made depending on these traits are not reliable.
根据类叶升麻次生木质部中多变的管状分子类型,认为以往积累的有关毛茛科植物管状分子类型及导管穿孔板类型是不全面的,因此以该性状为参考作出的有关某一个类群的原始性和进化性的推论也是不可靠的。

The tracheary elements in secondary xylems of Actaea asiatica root and rhizomes were observered with a scanning electron microscope and found to contain abundant types, which mainly included tracheids, tracheid-like vessels, fibriform vessels, and typical vessels. Of these types, the tracheids, tracheid-like vessels, fibriform vessels were first found. Scalariform perforation plates, reticulate perforation plates, mixed perforation plates and simple perforation plates were observed in the typical vessels and the reticulate perforation plates ,mixed perforation plates were first founded the lateral-wall perforation plates, multiple end walls and pit membrane vestige were also observed in the tracheary elements.
利用扫描电子显微镜对毛茛科类叶升麻根和根状茎次生木质部中的管状分子进行观察,发现其管状分子类型丰富,主要有:管胞、管胞状导管、纤维导管和典型的导管分子,其中管胞、管胞状导管和纤维导管为在该类群中首次报道;在导管分子中,存在着梯状穿孔板、网状穿孔板、混合型穿孔板和单穿孔板,其中网状穿孔板和混合型穿孔板为在该类群中的首次报道;对其导管分子上的侧壁穿孔板、多穿孔板和纹孔膜残余也进行了描述。

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。
