A new iridoid glycoside, namely 8-O-(threo-2, 3-dihydroxyl-3-phenyl-propionoyl)-harpagide (1), along with a new cinnamoyl glycoside named as cis-sibirioside A (2), were isolated from Scrophularia ningpoensis Hemsl. Their chemical structures were completely established by spectroscopic methods and comparison with related literatures. Compound 1 exhibited moderate antifouling effect against the settlement of Balanus amphitrite larvae with IC being 13.5 μg/mL and LC > 25 μg/mL.
从玄参中分离得到一个新的环烯醚萜苷，即8-O-(苏式-2,3-二羟基-3-苯基丙酰基)-哈帕苷(1)，以及一个新的肉桂酰苷，命名为顺式西伯利亚苷A(2)。通过光谱方法并与相关文献比较，完全确定了它们的化学结构。化合物1对纹藤壶幼虫的附着表现出中等程度的防污效果，其IC为13.5μg/mL，LC>25μg/mL。
