Effususol A (1), a new 9,10-dihydrophenanthrene, has been isolated from the medullae of Juncus effusus along with ten known compounds, effusol (2), dehydroeffusol (3), juncusol (4), dehydrojuncusol (5), juncuenin B (6), dehydrojuncuenin B (7), juncuenin D (8), luteolin (9), luteolin 5-methyl ether (10), and 4-hydroxy-2,3-dimethyl-2-nonen-4-olide (11). The structure of 1 was elucidated on the basis of spectroscopic data. 2, 4, 6, 7, and 8 have induced caspase-3-mediated cytotoxicity in HT22 cells.
从灯心草的髓部中分离出了一种新的9,10 - 二氢菲——灯心草酚A(1),以及十种已知化合物,即灯心草酚(2)、脱氢灯心草酚(3)、灯心草醇(4)、脱氢灯心草醇(5)、灯心草宁B(6)、脱氢灯心草宁B(7)、灯心草宁D(8)、木犀草素(9)、木犀草素5 - 甲醚(10)和4 - 羟基 - 2,3 - 二甲基 - 2 - 壬烯 - 4 - 内酯(11)。根据光谱数据阐明了1的结构。2、4、6、7和8在HT22细胞中诱导了半胱天冬酶 - 3介导的细胞毒性。
