Three new triterpenoid saponins polygalasaponins LI-LIII (1-3) with two acylation groups in oligosaccharide chain, together with three known saponins were isolated from the roots of Polygala japonica Houtt. (4-6). The neuroprotective effects of these compounds on neuron-like PC12 cells were evaluated in vitro. Compounds 5 and 6 show neuroprotective effects in Aβ₂₅₋₃₅ model at the concentration of 10 μM.
从远志根中分离得到了三种新的三萜皂苷
远志糖苷 LI-LIII（1-3），它们在寡糖链中有两个酰化基团，以及三种已知的皂苷（4-6）。这些化合物在体外对神经元样 PC12 细胞的神经保护作用进行了评估。在 10 μM 的浓度下，化合物 5 和 6 在 Aβ₂₅₋₃₅ 模型中表现出神经保护作用。
