Five previously undescribed guaialactone-type sesquiterpenes (1-5), called Lanicepsmines A-E, along with eleven know compounds (6-16), were isolated from the whole plant of Saussurea laniceps. NMR spectroscopic data analysis and MASS permitted the definition of their structures. The stereochemistry of the compounds was confirmed by ECD calculations. It is worth noting that compound 1 and 2 contain amino groups. Part of compounds were tested the anti-inflammasome activity, and compound 14 exhibited potent activity and decreased LDH level in a dose-dependent manner, with IC values of 0.698 μM.
