Abstract

Three new triterpenoid saponins, namely asprellinoids A-C (1-3), featuring a sulfate substitution in sugar moiety, were isolated from the stems of Ilex asprella (Hook. et Arn.) Champ. ex Benth. Their structures were elucidated by the spectroscopic data analyses including HR-ESI-MS, IR, and NMR spectra, and chemical method.

摘要

从岗梅（Ilex asprella (Hook. et Arn.) Champ. ex Benth.）的茎中分离出三种新的三萜皂苷，即岗梅皂苷A-C（1-3），其糖部分具有硫酸酯取代基。通过包括高分辨电喷雾电离质谱（HR-ESI-MS）、红外光谱（IR）和核磁共振光谱（NMR）等光谱数据分析以及化学方法阐明了它们的结构。
