The EtOH extract of the roots of Platycodon grandiflorum afforded two new triterpene saponins platycoside P (1) and platycoside Q (2). Their structures were elucidated based on spectroscopic means and hydrolysis products. These compounds were evaluated for inhibitory activity against LPS-induced TNF-α production in RAW 246.7 macrophages. Compounds 1 and 2 showed inhibitory activity with the inhibition
桔梗根的EtOH提取物提供了两个新的三萜皂苷Plateycoside P(1)和Ptycocoside Q(2)。根据光谱学手段和水解产物阐明了它们的结构。评估了这些化合物对RAW 246.7巨噬细胞中LPS诱导的TNF-α产生的抑制活性。化合物1和2在50μM时显示抑制活性,抑制率(%)分别为38.6和44.1。
