Result The parasites synchronized with sorbitol in vitro was treated by daphnetin and daphnetin-Fe complex.

经瑞香素（100μmol／L）作用1、2、3和4h后RNR活性分别被抑制7％、51％、69％和75％；在瑞香素浓度为0.1、1、100和1000μmol／L，作用6h后，RNR活性分别被抑制3％、31％、58％和93％；而瑞香素-Fe复合物作用6h后RNR活性分别被抑制8％、6％、11％和9％。

Methods The effect of daphnetin, daphnetin-Fe complex and desferrioxamine B on SOD activity of P. falciparum FOCI in vitro was determined with a SOD test-kit.

方法在恶性疟原虫FCC1株体外培养体系中，以SOD试剂盒检测瑞香素、瑞香素铁盐及去铁胺对疟原虫SOD活性的影响。

The effect of daphnetin and daphnetin-Fe complex on COX and RNR activity of P.falciparum was tested by ultraviolet spectrophotometer and electron spin resonance respectively.

结果 体外同步培养的恶性疟原虫经瑞香素（100μmol／L）作用2、4、8和12h后，COX活性分别被抑制了0、6％、73％和80％；在瑞香素浓度为0.1、1、100和1000μmol／L，作用6h后，COX活性分别被抑制3％、31％、53％和84％；而瑞香素-Fe复合物对COX的影响几乎消失。

Daphne diterpene esters are principal activitive components of Daphne genkwa, which is an endemic traditional Chinese medicine. Yuanhuacine has potent inhibition against several cancer cell lines. Inhibition against DNA topoisomerase I is probably its anticancer mechanism.

芫花为中国特有的瑞香科植物，主要有效成分为植物中罕见的瑞香烷型二萜原酸酯类化合物，其中芫花酯甲对多种癌细胞系有较强的抑制活性，对DNA拓扑异构酶I的抑制作用是其抗癌的可能机理。

On the basis of our research on Stellera chamaejasme L. and the literatures, the spectral and structural characteristics, the stereochemical researching methods, the distribution in the 3 subtribes of Thymeleaceae and chemotaxonomy of biflavonoids were concluded. We found that biflavonoids played a very important role in the chemotaxonomy of Thymelaeaceous plants.

通过对瑞香狼毒中双黄酮类化合物的研究，结合文献，总结了瑞香科中双黄酮类化合物的结构特点、波谱规律和立体化学研究方法；同时对双黄酮类化合物在瑞香科植物中的分布规律进行了总结，发现双黄酮类化合物在瑞香科的植物化学分类学方面具有重要作用。

No considerable effect was observed on the COX activity of P.falciparum treated with daphnetin-Fe complex. The tyrosyl free radical was tested to reflect the RNR activity of P.falciparum at various times by ESR.

结果 体外同步培养的恶性疟原虫经瑞香素（100 μmol/L）作用2、4、8和12 h后，COX活性分别被抑制了0、6%、73%和80%；在瑞香素浓度为0.1、1、100和1 000 μmol/L，作用6 h后，COX活性分别被抑制3%、31%、53%和84%；而瑞香素-Fe复合物对COX的影响几乎消失。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
