A new allose-containing triterpenoid saponin (1), along with a known saponin (2), were isolated from the aerial parts of Cephalaria ambrosioides. Their structures were determined by spectroscopic (2D-NMR and ESI-MS) methods. The preferred conformation of 1 was determined by the NOESY spectrum.
从 Cephalaria ambrosioides 的地上部分分离得到一种新的含阿洛酮糖的三萜皂苷(1)和一种已知的皂苷(2)。通过光谱(2D-NMR 和 ESI-MS)方法确定了它们的结构。通过 NOESY 谱确定了 1 的优势构象。
