Thirteen lignans, erythro-austrobailignan-6 (1), meso-dihydroguaiaretic acid (2), sauchinone (3), 1'-epi-sauchinone (4), saucerneol D (5), manassantin B (6), manassantin A (7), nectandrin B (8), machilin D (9), saucerneol F (10), saucerneol G (11), saucerneol H (12) and saucerneol I (13), were isolated from the ethyl acetate extract of the roots of Saururus chinensis. Among these compounds, 5 showed potent inhibitory activities against DNA topoisomerase I and II, and 5, 6, 7 and 10 showed mild cytotoxicities against HT-29 (IC(50) values; 13, 12, 11, and 10 microM, respectively) and HepG2 cell lines (IC(50) values; 16, 11, 12, and 11 microM, respectively).
从中华石龙尾的根的乙酸乙酯提取物中分离得到了 13 种木脂素,分别为赤式-澳洲柏木烷-6(1)、meso-二氢愈创木酸(2)、sauchinone(3)、1'-表-sauchinone(4)、saucerneol D(5)、曼纳辛汀 B(6)、曼纳辛汀 A(7)、nectandrin B(8)、machilin D(9)、saucerneol F(10)、saucerneol G(11)、saucerneol H(12)和 saucerneol I(13)。其中,化合物 5 对 DNA 拓扑异构酶 I 和 II 具有很强的抑制活性,化合物 5、6、7 和 10 对 HT-29(IC50 值分别为 13、12、11 和 10 μM)和 HepG2 细胞系(IC50 值分别为 16、11、12 和 11 μM)表现出轻微的细胞毒性。
