刘寄奴提取液对亚硝化反应的抑制作用

研究了不同浓度的刘寄奴提取物对亚硝胺(NDMA)合成的阻断作用及对亚硝酸钠的清除作用，并用Vc为对照品比较其阻断与清除能力.结果表明当提取物中固形物含量为63.52mg/mL(其黄酮含量相当于9.06 mg/mL)时，对亚硝胺的阻断力可高达93.88%；当提取物中固形物含量为111.16mg/mL(其黄酮含量相当于15.85 mg/mL)时，对亚硝胺的阻断力可高达89.36%；与1mg Vc比较，当提取物中黄酮含量也为1 mg时，对亚硝胺的阻断力和对亚硝酸钠的清除率分别为49.64%和21.99%；同样条件下Vc的阻断与清除率分别为62.14%和28.37%.

STUDY ON INHIBITINGNITROSATION BY EXTRACTOF ARTEMISIA ANOMALA S.MOORE

The disconnecting nitrosodimethylamin(NDMA) compost and scavenging sodium nitrite by extract of Artemisia Anomala S.Moore were studied and the capabilities of disconnection and scavenging of the extract were compared with ascorbic acid.The result showed that when the content of solid in the extract was 63.52 mg/mL(correspond to the content of flavonoids in the extract,9.06 mg/mL),the highest capability of disconnecting of NDMA was 93.88%,then when the content of solid in the extract was 111.6 mg/mL(correspond to the content of flavonoids in the extract ,15.8 mg/mL),the highest capability of scavenging sodium nitrite was 89.36%.Under the same condition,capabilities of disconnecting and scavenging were 49.64% and 21.99% respectively by 1 mg the extract of artemisia Anomala S.Moore, compared with by 1 mg ascorbic acid,capabilities of disconnection and scavenging were 62.14% and 28.37% respectively.
