Four new sinapyl alcohol derivatives dichrocephols A–D (compounds 1–4) were isolated from the lipo-soluble part of the whole herb of Dichrocephala benthamii C. B. Clarke, together with the known compound syringenin isovalerate (5). Their structures were elucidated on the basis of spectroscopic analysis. Their absolute configurations were established by the method of alkaline hydrohysis. Compounds 1–3 showed moderate cytotoxity against HeLa cells, with IC50 values of 14.8 μM, 51.6 μM and 81.6 μM, respectively. This is the first time that sinapyl alcohol derivatives were isolated from the genus Dichrocephala.
从 Dichrocephala Benthamii C. B. Clarke 整个草本的脂溶性部分中分离出四种新的芥子醇衍生物二色头酚 A–D(化合物 1–4),以及已知的化合物异戊酸注射器素 (5)。在光谱分析的基础上阐明了它们的结构。它们的绝对构型是通过碱性水解方法确定的。化合物 1-3 对 HeLa 细胞表现出中等的细胞毒性,IC50 值分别为 14.8 μM、51.6 μM 和 81.6 μM。这是首次从二色头藻属中分离出芥子醇衍生物。
