Zhang, Xiao-shu Cao, Jia-qing Shi, Guo-hui Liu, Zhen-ting Liu, Jing-xin Zhao, Yu-qing Two new isoaurones derivatives from <i>Callistephus chinensis</i> flower <div><p>Two new isoaurones derivatives were obtained from <i>Callistephus chinensis</i> flower. Their structures were elucidated on the basis of extensive spectroscopic analyses. Both of the new compounds were evaluated cytotoxic activity. Phytochemical investigation of <i>Callistephus chinensis</i> flower led to the isolation of two new isoaurones derivatives (<i>Z</i>)-4′,4,10-trihydroxy-siamaurone (<b>1</b>) and (<i>E</i>)-4′,4,10-trihydroxy-siamaurone (<b>2</b>). The structures of these new compounds were identified by the interpretation of spectroscopic data (mainly 1D and 2D NMR) and by comparison with data reported in the literature. Both of the new compounds were evaluated for their cytotoxicity.</p></div> spectroscopic;compound;data;2 D NMR;Callistephus chinensis flower;isoaurones derivatives 2015-07-20
