【Abstract】 Available component in the sample was extracted with acetone, and bromodiolone in the extract was separated on C18column (150mm×4. 6mm, 5· with the mobile phase, containing CH3OH and 0. 01mol ·LT1 H3PO4 in the ratio of 9 to 1, and determined with the UV-detector at the wavelength of 265nm. Linear relationship between the peak area and the concentration of standard bromodiolone was kept in the range of 0. 05 to 1. 0/ug. Detection limit was found to be 0. 015ml · L-1 CAS). Precision tests made on three concentration levels (i. e. 0. 05g ·kg-1 , 0. 15g · kg -1 and 0. 25g · kg-1 ) gave values of RSD( %) 1. 5%, 3. 0% and 3. 6% respectively. Recoveries obtained by standard addition method were in the range of 97. 5% to 100. 6%更多还原
