Vernonia leopoldi (Sch. Bip. ex Walp.) Vatke (Asteraceae) is one of the widely used anti-cancer traditional medicinal plants in Ethiopia, despite the lack of data to support its therapeutic efficacy. Here we describe the isolation of compounds from the plant and the investigation of their cytotoxicity and other bioactivities. We identified the novel sesquiterpene lactone (SL) 11ß,13-dihydrovernodalol
Vernonia leopoldi (Sch. Bip. ex Walp.) Vatke(菊科)是埃塞俄比亚广泛使用的抗癌传统药用植物之一,尽管缺乏数据支持其治疗功效。在这里,我们描述了从植物中分离化合物以及对其细胞毒性和其他生物活性的研究。我们首次从该植物中分离出新型倍半萜内酯 (SL) 11ß,13-二氢维诺达洛以及其他三种 SL(vernomenin、vernolepin 和 11ß,13-diHydrovernodalin)和三种黄酮类化合物(芹菜素、eriodyctiol 和木犀草素)时间。所有化合物的结构都是根据核磁共振波谱数据的广泛分析确定的,并通过高分辨率电喷雾电离质谱法确认。然后,我们研究了 SL 的生物活性,发现所有 SL 在低 μM 范围内均对 MCF-7 和 JIMT-1 乳腺癌细胞以及分光光度测定中评估的正常样 MCF-10A 乳腺上皮细胞具有细胞毒性。在伤口愈合试验中,用
