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.
