A new eremophilane sesquiterpene, (2 β )‐2‐deoxo‐2‐methoxytessaric acid ( 1 ), and two new eudesmane sesquiterpenes, (3 β ,10 α )‐3‐methoxyleudesma‐4,11(13)‐dien‐12‐oic acid ( 2 ) and (3 α ,4 β ,8 α )‐4‐(acetyloxy)‐3‐(2,3‐dihydroxy)‐2‐methyl‐1‐oxobutoxy‐8‐hydroxyeudesm‐7(11)‐eno‐12,8‐lactone ( 3 ), along with the ten known compounds 4 – 13 were isolated from the aerial parts of Laggera pterodonta. The structures of the new compounds were elucidated by spectroscopic analyses, including 2D‐NMR data.
