isolated from the aerial parts of Agrimonia pilosa Ledeb., along with eight known flavanonol glucosides (3-10). Their structures were determined on the basis of spectroscopic analysis. In addition, these compounds were evaluated to determine their acetylcholinesterase inhibitory activities. The results indicated that these compounds have moderate inhibitory effects, with IC50 values ranging from 76.59 ± 1
从中分离出两个新的黄烷醇葡糖苷异构体(2R,3S)-dihydrokaempferol3-O-β-D-glucoside(1)和(2S,3R)-dihydrokaempferol3-O-β-D-glucoside(2)。姬松茸的地上部分,以及八种已知的黄烷醇糖苷(3-10)。它们的结构是在光谱分析的基础上确定的。另外,评估这些化合物以确定其乙酰胆碱酯酶抑制活性。结果表明,这些化合物具有中等抑制作用,IC50值范围为76.59±1.16至97.53±1.64μM,但化合物1和4无效。
