本文探索丁公藤中抗风湿成份东莨菪素的紫外导数光谱测定法.并应用于冯了性风湿跌打药酒中该成份的测定.结果证明,题示物的二阶导数光谱在特定条件下,能完全清除较高的背景吸收,于390nm谷-420nm蜂振幅D值与药酒中题示物浓度有良好线性关系.以单味丁公藤酒作标准.与东莨菪素纯品对照测得回收率可达100.9%. This article explored the ultraviolet derivative spectrometry of the anti-rheumatic component scotoxin from Dinggong rattan. It was applied to the determination of this component in Feng’s rheumatoid batter drug. The results show that the second derivative spectrum of the indicator can be The background absorption was completely eliminated. The linear relationship between the amplitude D of the bee at 390 nm and the peak wavelength of 420 nm and the concentration of the title indicator in the wine was determined. The single vinegar was used as the standard. The recovery rate was comparable to that of the eucalyptus pure product. 100.9%.
