Description:
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.
