Ten naphthalene derivatives including two unusual glycosides possessing a naphthalene-fused piceid via a [C8'-O-C6-C5-C7']-trans-dihydrofuran ring, two flavan derivatives, as well as sixteen known phenolic compounds, were isolated from Polygonum cuspidatum. The structures were determined by extensive NMR, MS, CD data, and chemical evidence. In the in vitro neuroprotective assays, at the concentration of 10 μM, five of these compounds exhibited significant effects against PC12 cells injured by rotenone.
从虎杖中分离出10种萘衍生物，包括两种不寻常的糖苷，它们通过一个[C8'-O-C6-C5-C7']-反式二氢呋喃环与萘并云杉新苷相连，两种黄烷衍生物，以及16种已知的酚类化合物。通过广泛的核磁共振（NMR）、质谱（MS）、圆二色光谱（CD）数据和化学证据确定了其结构。在体外神经保护试验中，在10 μM的浓度下，其中5种化合物对鱼藤酮损伤的PC12细胞表现出显著的保护作用。
