Abstract


Selaginella (Selaginella sp.) Plant belongs ferns door Dansong Gang Selaginellaceae, is a perennial herb, is ancient and modern plant kingdom on earth is an important part of the world there are about 700 kinds of about 60 species, distributed throughout the country, extremely rich in resources. There are more than 20 kinds of which can be used as medicinal. In recent years, pharmacological studies with plant resources and the deepening of Selaginella more and more Chinese and foreign researchers' attention, especially the genus is rich in flavonoids dual anti-tumor and anti-viral role of obvious , is a potential anti-tumor and antiviral drugs. Yanzhou Selaginella (Selaginella involvens Spring.) Is a kind of folk use antiviral drugs with rare Selaginella plants used for the treatment of hepatitis B virus. In order to further the development and application of Yanzhou Selaginella medicinal value, this paper systematically studied the Yanzhou Selaginella contains chemically active ingredient and the main analysis Yanzhou Selaginella medicinal ingredient. Test column chromatography on silica gel using, a polyamide column chromatography, sephadex column chromatography, reversed phase C 18 column chromatography and recrystallization techniques, from Yanzhou Selaginella 13 compounds have been purified. Use of modern spectroscopic analysis and chemical methods and other means, such as 1 HNMR, 13 C NMR, DEPT, HSQC, 1 H- 1 H COSY, IR, MS, etc., of which 10 compounds were identified, including three pairs of flavonoids, a steroidal alkaloid glycosides, two sterols, two fatty acids, a triterpenoids, a steroidal carbohydrates. These compounds were isolated from this plant, triterpenoids and steroids carbohydrates for the first time from this genus were isolated, and got a steroidal glycoalkaloids is a new compound. Respectively, by steam distillation from Yanzhou Selaginella (S.involvens Spring), Cuiyun grass (S.uncinata Spring), dark green Selaginella (S.doederleinii Hieron) whole plant essential oil was extracted and analyzed by gas chromatography - mass spectrometry analysis of its volatile oil composition and content. The three Selaginella volatile oil components were compared. Confirm their volatile oil containing mainly higher alkanes, alkenes, alcohols, ketones, phenols and organic acids, as Selaginella provide the basis for further research use. Explores the use of cyclic voltammetry determination and compared three pairs of electrochemical properties of flavonoids, and measured at different pH values ??PBS buffer solution biflavonoids polarization curves. Thesis results herbal active ingredients Yanzhou Selaginella stated pharmacology studies provide important theoretical basis for our development and utilization of natural plant and herbal modern research has certain reference value.
