From the dried roots of Rauwolfia serpentina were isolated five new indole alkaloids, N(b)-methylajmaline (1), N(b)-methylisoajmaline (2), 3-hydroxysarpagine (3), yohimbinic acid (4), isorauhimbinic acid (5), a new iridoid glucoside, 7-epiloganin (6), and a new sucrose derivative, 6'-O-(3,4,5-trimethoxybenzoyl)glomeratose A (7), together with 20 known compounds. The structures of the new compounds were
从蛇毒非洲菊的干燥根中分离出五个新的吲哚生物碱,N(b)-甲基ajmaline(1),N(b)-甲基异ajmaline(2),3-羟基沙丁胺碱(3),育亨宾酸(4),异丁烯二酸( 5),一种新的虹彩苷葡糖苷7-表柔铁蛋白(6)和一种新的蔗糖衍生物6'-O-(3,4,5-三甲氧基苯甲酰基)glomeratose A(7),以及20种已知化合物。通过光谱和化学方法确定了新化合物的结构。评估了所选生物碱对拓扑异构酶I和II的抑制活性以及它们对人早幼粒细胞白血病(HL-60)细胞系的细胞毒性。
