| Abstract: | Objective: To establish a nitrogen determination method for determining capsaicin in rotenone-capsaicin suspension.Methods: The capsaicin of suspension was determined by the nitrogen determination method.The results were regulated by blank control and protein control.Results:The content in suspension was 0.25 g/100 mL and RSD was 1.77%.The mean average recovery of the method was 100.67% and RSD was 1.65%.The error of the protein influence was in control.Conclusion:The method was simple and accurate.It could be used to quality control of the rotenone-capsaicin suspension. |
| Keywords: | nitrogen determination method rotenone-capsaicin suspension determination of content |
