Four previously undescribed ginsenosides, along with five known analogues were isolated from wild ginseng by a UPLC-QTOF-MS-guided fractionation procedure. Their structures were elucidated on the basis of spectroscopic and spectrometric data (1D and 2D NMR, HR-ESI-MS). The isolated compounds could significantly inhibit the cigarette smoke extract (CSE)-induced inflammatory reaction in A549 cells. The HDAC2 pathway might be involved in the protective effect against the CSE-mediated inflammatory response in A549 cells.
通过超高效液相色谱-四极杆飞行时间质谱（UPLC-QTOF-MS）引导的分级分离程序，从野生人参中分离出四种先前未描述的人参皂苷以及五种已知类似物。基于光谱和光谱数据（一维和二维核磁共振、高分辨率电喷雾电离质谱）阐明了它们的结构。分离出的化合物可显著抑制香烟烟雾提取物（CSE）诱导的A549细胞炎症反应。组蛋白去乙酰化酶2（HDAC2）途径可能参与了对A549细胞中CSE介导的炎症反应的保护作用。
