摘要
Two new furostanol glycosides, aspacochinosides L （1） and M （2）, were isolated from the roots of Asparagus cochinchinensis （Lour.） Merr. Their structures were determined by chemical methods and NMR spectral analysis, including extensive 1D and 2D NMR experiments. Compounds 1 and 2 were investigated for their anti-neuroinflammatory activity in LPS-induced BV-2 cells. Compound 2 showed moderate inhibitory effect on NO production in LPS-induced BV-2 microglial cells with IC 50 value of 32.26 μM.
从天门冬的根中分离得到两个新呋甾烷型皂苷aspacochinoside L(1)和aspacochinoside M(2),通过化学和波谱学方法确定了化合物1和2的结构。利用脂多糖(LPS)诱导的小胶质细胞(BV-2)炎症模型,测试了化合物的抗炎活性,其中aspacochinoside M的IC50值为32.26μM。
