资助项目:In this thesis, the chemical constituents of two medicinal plants, Pogostemon cablin (Blanco) Benth and Jasminum sambac (L.) Ait, were systematically studied. Thirty-three compounds, including five new ones (one monoterpene and four sesquiterpenoids), have been obtained by using varied chromatographic methods and separation techniques. These compounds referred to monoterpenes, sesquiterpenoids, secoiridoids, flavonoids, benzyl alcohol derivatives, phenylpropanoids, lignans, tannins and so on. Their structures were elucidated by detailed spectroscopic analysis, including 1D, 2D NMR, UV, IR and MS techniques. In addition, the chemical and bio-activities researches on the family Fagaceae were summaried. The detailed contents are shown as following: Chapter 1. The chemical constituents of Pogostemon cablin. P. cablin belong to the genus Pogostemon of Labiatae. As a native species of Philippines, Malaysia and India, it has been introduced into China and cultivated widely in Guangdong, Hainan, Guangxi, Taiwan and Yunnan provinces of China. Thirteen compounds, including eight sesquiterpenoids and five flavonoids, were identified from the methanol extracts of the P. cablin. Of eight sesquiterpenoids, four were the new ones. The results of this study will provide the basis for the further using of the herb. Chapter 2. The chemical constituents of Jasminum sambac. J. sambac is one of the family Oleaceae. Its flowers have been commonly used for smoking jasmine tea. J. sambac was native to the south and west of China, India and Arab. The main growing place is Persian Gulf. In this chapter, 20 compounds including one new monoterpenes were obtained from the flower of J. sambac after smoking tea. These constituents referred to monoterpenes, secoiridoids, benzyl alcohol derivatives, flavonoids, phenylpropanoids, lignans, tannins and so on. These results will provide some basic for further using of this plant. Chapter 3. The Advance of Chemical Components and Bioactivity of Fagaceous Plants since 1970. The above research resulted three papers, including two research articles and one review.
