An unprecedented dimeric triterpenoid, designated dibelamcandal A, with a six-membered ring linking two iridal type triterpenoid nuclei, was isolated from the rhizome of Belamcanda chinensis. Its structure was determined by extensive spectroscopic measurements, including IR, ESI-MS, HR-ESI-MS, and 1D and 2D NMR. It demonstrated significant molluscicide activity against Pomacea canaliculata.
从国产射干Belamcanda chinensis 的根茎中分离得到了一种前所未有的二聚型三萜类化合物，命名为 dibelamcandal A，它由一个六元环连接两个伊里德型三萜核组成。通过广泛的光谱测量，包括 IR、ESI-MS、HR-ESI-MS 以及 1D 和 2D NMR，确定了其结构。该化合物对福寿螺Pomacea canaliculata 具有显著的杀螺活性。
