Compounds were isolated from a methanol extract of the dried stem barks of Viburnum sargentii Koehne. The structures of the compounds, namely 9'-O-methylvibsanol (3), furcatoside A (4) and lareciresinol (5) were elucidated by analysis of spectroscopic data and comparison with values for previously known analogues. In addition, (+)-catechin (1), (+)-epicatechin (2) were also isolated. This work also examined the cytotoxic effects of three compounds 3-5 (25-100 microM) in MCF-7 and A549 cells after 24, 48 and 72 h of exposure. Our results showed that 9'-O-methylvibsanol (3) exhibited strong concentration-dependent anticancer effects according to the MTT assay and produced morphological changes consistent with apoptosis, as confirmed by Ho3342 staining analysis revealed that more apoptotic cells were observed after 9'-Omethylvibsanol (3) treatment.
化合物从 Viburnum sargentii Koehne 的干燥茎皮的甲醇提取物中分离得到。通过分析光谱数据并与以前已知类似物的值进行比较,阐明了化合物的结构,即 9'-O-甲基 Vibsanol(3)、Furcatoside A(4)和Lareciresinol(5)。此外,还分离出了(+)-儿茶素(1)和(+)-表儿茶素(2)。这项工作还研究了三种化合物 3-5(25-100 μM)在 MCF-7 和 A549 细胞中暴露 24、48 和 72 h 后的细胞毒性作用。我们的结果表明,根据 MTT 测定,9'-O-甲基 Vibsanol(3)表现出强烈的浓度依赖性抗癌作用,并产生与凋亡一致的形态变化,这通过 Ho3342 染色分析得到证实,分析显示,在用 9'-O-甲基 Vibsanol(3)处理后,观察到更多的凋亡细胞。
