The EtOH extract of the roots of Platycodon grandiflorum afforded twonewtriterpenesaponins 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
