A new phenyldihydronaphthalene-type lignan, vitexdoin F (1), along with 22 known lignan derivatives (2-23) was isolated from the seeds of Vitex negundo var. cannabifolia. Their structures were established by comprehensive 1D and 2D NMR spectroscopic analyses. The antioxidant activities of these lignans were evaluated through 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging assays, and 16 of these isolates exhibited obvious radical-scavenging effect on the stable-free radical, DPPH.
从黄荆变种大麻叶的种子中分离出一种新的苯基二氢萘型木脂素——牡荆脂素F（1），以及22种已知的木脂素衍生物（2 - 23）。通过全面的一维和二维核磁共振光谱分析确定了它们的结构。通过1,1 - 二苯基 - 2 - 苦基肼（DPPH）自由基清除试验评估了这些木脂素的抗氧化活性，其中16种分离物对稳定自由基DPPH表现出明显的自由基清除作用。
