Purification of the precipitate obtained from juice oil of Citrus hassaku by chromatography afforded a main compound, whose structure was determined to be 7-geranyloxycoumarin, aurapten, on the basis of chemical and spectral evidence. This compound was isolated from Citrus hassaku for the first time. The antimicrobial activity of aurapten and several synthesized related coumarins against 5 bacteria and a fungus was investigated using the agar dilution method. Auraptenal exhibited the highest activity among them, at the concentration of 25 ppm, against all the microorganisms tested in this study.
通过色谱法对从哈萨库柑橘果汁油中获得的沉淀物进行纯化,得到了一种主要化合物,根据化学和光谱证据,确定其结构为 7-geranyloxycoumarin, aurapten。这是首次从柑橘类植物中分离出这种化合物。采用琼脂稀释法研究了 Aurapten 和几种合成的相关香豆素对 5 种细菌和一种真菌的抗菌活性。当浓度为 25 ppm 时,枳椇醛对本研究中测试的所有微生物都表现出最高的活性。
