Abstract:
Lycium barbarum L. was used as raw material，and spectrophotometry was used to determine content of ammonium alkaloids in methanol extract of Lycium barbarum L.，based on the reaction of ammonium alkaloids with Remecke salt.The aim was to establish a method for quantitative determination of ammonium alkaloids in methanol extract of Lycium barbarum L.The results showed that the average recovery rate of filtrate and precipitation methods was 97.57%and 98.06%，and relative standard deviation was 1.02%and 1.10%(n=6)，respectively.Conclusion，the results were consistent for determination of ammonium alkaloids by the two methods，and filtrate method was comparatively simple.
