Phytochemical investigation of Eupatorium kiirunense has resulted in the isolation of eight new sesquiterpene lactones, constituted by five germacranolides, eupakirunsins A-E (1-5), and three heliangolides, eupaheliangolide A (6), 15-acetoxyheliangin (7), and 3-epi-heliangin (8), in addition to the known heliangin (9) and 8,10-epoxy-9-acetoxythymol angelate (10). The structures of the new compounds were established through detailed analysis of their spectroscopic data. Compounds 6, 8, and 9 exhibited cytotoxicity against human oral epidermoid (KB), cervical epitheloid (Hela), and liver (hepa59T/VGH) carcinoma cells.
对基隆泽兰(Eupatorium kiirunense)进行植物化学研究,已分离出8种新的倍半萜内酯,其中包括5种吉马烷型内酯,即基隆泽兰素A-E(1-5),以及3种泽兰内酯,即泽兰内酯A(6)、15-乙酰氧基泽兰素(7)和3-表-泽兰素(8),此外还分离出已知的泽兰素(9)和8,10-环氧-9-乙酰氧基百里香酸当归酯(10)。通过对其光谱数据的详细分析确定了新化合物的结构。化合物6、8和9对人口腔表皮样(KB)、宫颈上皮样(Hela)和肝癌(hepa59T/VGH)细胞具有细胞毒性。
