Abstract
Steam distillation oil (SDO) and simultaneous distillation oil (SDEO) were obtained from Tagetes Erecta L. leaf of Heilongjiang province by steam distillation method and simultaneous distillation method, respectively. The yields were 0.0943% and 1.005%. Compared the differentiation of essential oil through the GC-MS analysis, the result indicated that there were twenty-nine kinds of compounds can be confirmed from SDO and fifty-one kinds can be confirmed from SDEO. The two kinds of essential oil were assayed for affinity to scavenge sodium nitrite for the purpose of characterizing mechanisms of nitrite cleaning activity. Both show strong nitrite cleaning activity up to a concentration of 0.1mL.The maximum scavenging rate was 95.18% (SDO) and 54.28% (SDEO).
