| 摘 要： | 测定蓖麻籽饼中蓖麻碱的含量，用紫外分光光度计，在313nm处测定蓖麻碱的吸光度，测定了七种样品，结果表明减毒之后蓖麻碱含量明显降低，回收率实验表明，蓖麻碱回收率为94.31%，RSD为1.18%,紫外分光光度法测定蓖麻碱的含量具有简便、准确、稳定、重现性好的特点。

| Abstract: | ［Objective］Quantification of ricinine in castor pomac e.［method］To determine absorbance of ricinine at 313 nm by UV-300［Result］Se ven samples was determined,the result indicate that the quantity of ricinine in castor pomace which treated by reducing poison is lower than those which wasnt treaed by reducing poison,the rate of recovery of ricinine is 94.31%，RSD is 1 .18%(n＝5)［Conclusion］The method that quantity determinetion of ricinine in c astor pomace by Ultroviolet spetrometry is simple,accurate,stability and good re coverty. |
