Two new phenanthrene glycosides, dioscopposide A and dioscopposide B (1 and 2), were isolated from the rhizomes of Dioscorea opposita. Their structures were determined primarily on the basis of 1D and 2D NMR techniques, MS studies, and chemical methods. All the isolates were evaluated for their inhibitory effects on the lipopolysaccharide-induced nitric oxide production using murine macrophage RAW
从薯Di的根茎中分离出两种新的菲苷,薯po甙A和薯po甙B(1和2)。它们的结构主要根据1D和2D NMR技术,MS研究和化学方法确定。使用鼠巨噬细胞RAW 264.7细胞评估所有分离物对脂多糖诱导的一氧化氮产生的抑制作用。薯cop甙A和薯cop甙B的IC 50值分别为5.8和7.2μM。
