中文摘要：

二包含氯的 phenylpropanoid enantiomers (1a/1b 和 2a/2b ) 从 Acorus tatarinowii 的根茎被孤立。有趣地，这些光异构体(1a/1b 和 2a/2b ) 在一样的工厂被共存，它从类 Acorus 作为第一个包含卤素的自然产品被描绘。他们的结构和绝对配置被分光镜的分析和单个水晶的 X 光检查衍射的联合阐明，由一个修改 Moshers 方法帮助了。phenylpropanoid 异构体(1a/1b 和 2a/2b ) 与五根人的癌症房间线用 DPPH 试金和细胞毒素的活动为他们的抗氧化剂活动被作比较。

英文摘要：

Two pairs of chlorine-containing phenylpropanoid enantiomers（1a/1b and 2a/2b） were isolated from the rhizomes of Acorus tatarinowii. Interestingly, these optical isomers（1a/1b and 2a/2b） were co-existed in the same plant, which were characterized as the first halogen-containing natural products from the genus Acorus. Their structures and absolute configurations were elucidated by a combination of spectroscopic analysis and a single-crystal X-ray diffraction, assisted by a modified Mosher＇s method. The phenylpropanoid isomers（1a/1b and 2a/2b） were evaluated for their antioxidant activities using DPPH assay and cytotoxic activities against five human cancer cell lines.
