本文研究了蓖麻碱的分离提纯方法及薄层层析定量。对蓖麻碱的提纯方法进行了改进。用氧化铝ＧＦ做固定相，甲苯∶异丙醇∶乙醇做流动相分离蓖麻碱，然后置于ＣＳ－９３０双波长薄层扫描仪中进行定量，提高了测试精度。
In this paper, the isolation and purification of ricinine and TLC quantitative analysis. The purification of ricinine was improved. GF alumina as the stationary phase, toluene: isopropanol: ethanol as the mobile phase separation of ricinine, and then placed in CS-930 dual-wavelength thin layer scanner for quantitative, improve the test accuracy.
