【摘要】 从白头翁(Pulsatilla Chinesis)植物中提取与人工合成了毛莨科植物含有的原白头翁素和白头翁素.经UV、IR、NMR、MS 等光谱分析鉴定,结构正确.经果蝇、水稻白叶枯病菌等生测试验表明,原白头翁素具有杀虫活性和显著的抑菌活性.原白头翁素聚合后,生物活性明显降低.更多还原

【Abstract】 Protoanemonin and anemonin which exist in Ranunculaceae were extractedfrom Pulsatilla Chinesis and synthesized in our laboratory.It is proved re-spectively that their structures are correct by their spectra(UV,IR,NMR,MS).Through tests on D.melanogaster and Xanthomonas oryzac Douson,pro-toanemonin shows pesticidal and relatively high fungus-inhibiting activities.When protoanemonin polymerized,these activities are distinctly decreased.更多还原
