中文摘要本论文由三部分共6 章组成。第一部分报道了余甘子、细叶草乌和土荆皮等三种药用植物的化学成分研究成果;第二部分报道了细叶草乌和土荆皮中分离得到的化合物的活性测试,以及这两种植物的质谱分析;第三部分概述了土荆皮的研究现状。第一部分包括1-3 章。在第1 章、第2 章和第3 章中分别报道了余甘子(Phyllanthus emblica L.) 、细叶草乌(Aconitum richardsonianum var.pseudosessiliflorum) 和土荆皮( pseudolarix kaempferi) 的化学成分。采用正、反相硅胶柱层析等各种分离方法,从余甘子中共分离出10 个化合物,其中1 个为新化合物,另外还有2 个为首次从该植物中分离得到。细叶草乌的化学成分研究尚未见报道,我们从该植物中共分离出15 个化合物,其中6 个为二萜生物碱,9个为非生物碱成分。从土荆皮中分离得到16 个化合物,其中8 个二萜、1 个三萜和7 个其它类型化合物,其中有4 个化合物为首次在该植物中分离得到;从土荆皮挥发油中分离鉴定出了22 个化合物,占挥发油总量的90%。第二部分包括4-5 章。第4 章报道了从细叶草乌和土荆皮中分离得到的13个化合物的药理活性研究,结果显示,展花乌头宁和土荆乙酸葡萄糖苷等表现出较高的组织蛋白酶K 抑制活性;土荆乙酸葡萄糖苷表现出较高的组织蛋白酶B抑制活性;8-去乙酰滇乌碱表现出较高的蛋白质酪氨酸磷酸酶抑制活性。第5 章报道了细叶草乌和土荆皮总浸膏的质谱( ESI-MS ) 分析,研究结果表明,ESI-MS 法可以简单快速地检测这两种植物的主要成分;通过ESI-MS2 分析初步探讨了一些化合物的裂解规律,尝试质谱在其结构测定中的具体应用。第三部分为第6 章。从化学成分、药理、构效关系、主要成分的定量分析、及其合成研究等方面概述了土荆皮的研究进展。 This dissertation consists of three parts. The first part elaborate thephytochemical investigation of three medicinal plants, Phyllanthus emblica L.,Aconitum richardsonianum var. pseudosessiliflorum and pseudolarix kaempferi. Thesecond part reported the bioassay of 13 constituents from Aconitum richardsonianumvar. pseudosessiliflorum and pseudolarix kaempferi, and ESI-MS analysis of these twoplant . The third part is a review on the research progress of pseudolarix kaempferi.The first part is composed of three chapters. Chapters 1-3 focus on the isolationand identification of chemical constituents from Phyllanthus emblica L., Aconitumrichardsonianum var. pseudosessiliflorum and pseudolarix kaempferi. 10 compoundsincluding a new tannin were isolated from the fruits of Phyllanthus emblica by repeatcolumn chromatography over normal and reversed phase silica gel, 2 of them werefirstly reported in this plant. The chemical constituents of Aconitum richardsonianumvar. pseudosessiliflorum never reported before, 15 compounds including 6 diterpenealkaloids were isolated and identified from the roots of this plant. 16 compoundsincluding 8 diterpenes , 1 triterpene and 7 other compounds were isolated from the bark of pseudolarix kaempferi, among them, 4 compounds were firstly reported fromthe EtOH extracts of this plant, and 22 compounds were identified from its essentialoil, representing 90% of the total essential oil.The second part includes chapters 4 and 5. Chapter 4 reported thepharmacological activities of 13 compounds isolated from Aconitum richardsonianumvar. pseudosessiliflorum and pseudolarix kaempferi. Results demonstrated that chasmanine and pseudolaric acid B-β-D-glucoside exhibit relatively high anti-Cathepsin K activities; pseudolaric acid B-β-D-glucoside exhibits relatively highanti-Cathepsin B activity; 8-deacetyl-yunaconitine exhibits relatively high anti-PTP1Bactivity. Chapter 5 reported the ESI-MS analysis of extractions from Aconitumrichardsonianum var. pseudosessiliflorum and pseudolarix kaempferi, it was showedthat ESI-MS can be used as an useful tool in analyzing the major constituents of thesetwo plant much quick and easy, in addition, the fragmentation rules of somecompounds were discussed, in order to find some applications of ESI-MS2 method in their structure determination.The third part is a review on the research progress of pseudolarix kaempferi,including the chemical constituents, pharmacology, structure-activity relationship(SAP), quantitative analysis and synthesis of the major constituents.
