Objective: Expriments were conducted on different extracts of Acroptilon repens to determine their ability to clean sodium nitrites and block the synthesis of nitrosamines . Methods: Soxhlet Extraction and Immersed Extraction methods were used to extract effective components of Acroptilon repens and capability of cleaning nitrite and blocking synthesis of nitrosamine of the extracts were measured using Spectrophotometry in a condition that simulated human gastric juice, and compared the results with Vc . Result: Rates of cleaing sodium nitrite and the blocking synthesis of nitrosamines of the extracts was positively correlated to its concentration, rate of cleaing sodium nitrite of ethanol extracts and water extracts were up to 60% , 58% respectively while the rate of blocking synthesis of nitrosamine were 86. 6% ,48.6% respectively. Conclusion: It is revealed, based on the results of the comparision with Vc, that extracts of Acroptilon repens have relatively strong capacity to clean sodium nitrite and block the synthesis of nitrosamines.
