BHA具有对抗双香豆素所引起的QR催化活性降低的作用，并具有显著降低双香豆素＋阿霉素所导致的ALT、LDH、CK及肝MDA含量增高的作用。

BHA could resist the decrease of QR activity caused by dicoumarol . BHA had caused a significantly decrease of serum ALT , LDH , CK , and liver MDA amount induced by dicoumarol plus doxorubicin .

但含有对双香豆素高度敏感的还原菸酰胺核苷酸脱氢酶，其性貭与Ernster所提出的DT黄递酶很相似。

However , it contained a highly active reduced nicotinamide nucleotide dehydrogenase , which was found to be sensitive to dicumarol and was probably identical with the ' DT ' diaphorase reported by Ernster et al .

华法林属双香豆素衍生物，是常用的口服抗凝血药，可预防和治疗血栓栓塞性疾病。

Warfarin , a coumarin derivative , is widely used as an oral anticoagulant drug in the treatment and prevention of thromboembolic disorders .

3种菌在草木犀培养物中分离到香豆素和双香豆素，而胡麻饼和玉米粉培养物中未分离到上述产物。

Coumarin and dicoumarin were isolated from the three fungi inoculated clover culture medium , but were not isolated from flax cake and maize powders .

华法令是目前最常用的此类药物，它是一种合成的双香豆素类，比天然复合物强5-10倍。

Warfarin , a synthesized version of dicumarol , is 5 to 10 times stronger than the original compound and is the most commonly used oral anticoagulant .
