Seven new limonoids, namely, xylorumphiins E-J (1-2 and 4-7) and 2-hydroxyxylorumphiin F (3), along with three known derivatives (8-10), were isolated from the seeds of Xylocarpus rumphii. 2-Hydroxyxylorumphiin F (3) and xylorumphiin I (6) displayed moderate inhibitory activity against nitric oxide production from lipopolysaccharide-activated macrophages with IC50 values of 24.5 and 31.3 μM, respectively.
从毛瓣木果楝种子中分离得到7个新柠檬苦素,即木果楝素E-J(1-2和4-7)和2-羟基木果楝素F(3),以及3个已知衍生物(8-10)。2-羟基木果楝素F(3)和木果楝素I(6)对脂多糖激活的巨噬细胞产生一氧化氮具有中等抑制活性,IC50值分别为24.5和31.3 μM。
