phenolic glycosides, Pubescenosides N-P (3-5), along with nineteen known ones, including liganoids, hemiterpenoids and caffeoylquinic acid derivates, were isolated from the roots of Ilex pubescens. Their structures were elucidated from extensive spectroscopic analysis, including 1D and 2D NMR experiments. This study is the first to report monoterpene glycosides with β-pinene aglycone in Aquifoliaceae
从Ilex的根中分离出5种新的代谢物,包括2种单萜糖苷LM(1-2)和3种酚类糖苷,NP(3-5),以及19种已知的代谢物,包括褐藻素,半萜类和咖啡酰奎尼酸衍生物。 pubescens。通过广泛的光谱分析(包括1D和2D NMR实验)阐明了它们的结构。该研究是第一个报道单叶植物中单萜糖苷与β-pine烯糖苷配基的研究。在体外评估了其中的9种化合物的抗血小板聚集活性。其中,与阿司匹林相比,化合物3和4对ADP诱导的血小板聚集表现出中等抑制作用[抑制(%):分别为32.3和33.6]。
