? 2021 Elsevier B.V.Seven new terpenes and its derivatives classified into a p-menthane glycoside (1), a guaianolide glycoside (2), three eudesmane and its glycosides (3–5), and two mono-terpene derivatives (9 and 10) were isolated from Ainsliaea bonatii, together with three known guaianolides (6–8). Their structures were elucidated by spectroscopic data analysis, and absolute configurations were determined by DP4+ probability analysis via calculated 13C NMR data of isomers. Compounds 6 and 9 showed nitric oxide (NO) inhibitory effects in LPS-induced RAW 264.7 macrophage cells with IC50 values of 9.3 and 10.6 μM, respectively.
