The determination of content of rotenone in Tephrosia vogelii leaves and extract time

  • 摘要: 用苯和氯仿作溶剂,采用冷浸法,对紫花非洲山毛豆叶片进行多次提取,测定了非洲山毛豆叶片中鱼藤酮的含量和提取时间.结果表明,紫花非洲山毛豆叶片中w(鱼藤酮)为0.69%.用苯冷浸提取2次,每次提取2d,对鱼藤酮的提取率为66.37%;提取3次,提取率为76.47%.
    Abstract: The content of rotenone in leaves of Tephrosia vogelii and the extract time were determined by extracting purple variety leaves of T. vogelii repeatedly with benzene and chloroform as solvents by cold dipping method. It was showed that the precise content of rotenone in T. vogelii leaves was 0.69%. When the leaves of T.vogelii were extracted for 2 times and 3 times with benzene by cold dipping, for 2 days each, the extract rate of rotenone was 66.37% and 76.47%, respectively.
