Abstract: Objective Infrared spectroscopy was used to study on both raw material and different degree water processing varieties extract of Radix Aconiti kusnezoffii,to observe the changes of main toxic components in processing,and thus to improve the quality of Radix Aconiti kusnezoffii processed products.Methods Fu Liye transform infrared spectroscopy was adopted to study the infrared spectrum characteristic of raw materials and different degree water processing varieties of.Radix Aconiti kusnezoffii.Results ①Aconitine and hypaconitine infrared spectrum showed that 1717 cm-1,1727 cm-1 and 1711 cm-1 is the C=O stretching vibration peak.It is a diester alkaloids characteristic peaks; ② although absorption peak of all vesicular samples had a certain change,it still existed diester alkaloids absorption peak,indicating the incomplete hydrolysis; ③ boiled aconite processing methods demonstrated diester alkaloids absorption peak shift in the water sample.Conclusion Diester alkaloids in Radix Aconiti kusnezoffii shows a positive relation with its time soaked in water.
