| 摘 要： | 用系统溶剂提取法得到天葵的石油醚、氯仿、乙酸乙酯、丙酮、乙醇、甲醇和水提取物，天葵提取物的总提取率为38．76％。在烟叶半叶枯斑法活性测定离体试验中，首次发现天葵块根的7种不同溶剂提取物都具有较好的抗TMV生物活性，天葵提取物对TMV钝化作用范围为34．12％～68．09％，其中以天葵的石油醚、丙酮和乙醇提取物效果较好，钝化效果分别为68．09％、63．28％和60．59％；保护作用范围为17．48％～65．26％，以石油醚提取物保护作用最好，抑制率达65．26％；治疗作用范围为12．79％～34．24％，丙酮提取物治疗抑制率可达34．24％． |

| Abstract: | In this study,petroleum ether,chloroform,ethyl acetate,acetone,ethanol,methanol and water extracts of S.adoxoides were obtained by adopting systemic solvent extraction method.The total extraction percentage of S.adoxoides extract was 38.76 %.In vitro experiment,all solvent extracts of S.adoxoides root were found to have the anti-TMV activity for the first time,and their passivation action range was 34.12%-68.09%.Among these seven extracts,extracts of petroleum ether,acetone and ethanol to TMV had more passi... |
