The invention belongs to the technical field of medicines, and particularly relates to a triterpenoid-diterpenoid hybrid dimer (as shown in formulas 1, 2 and 3) which is separated from branches and leaves of a pinaceae (Pseudotsuga) plant (Pseudotsuga forresterii Craib) and has a novel structure, and application of the triterpenoid-diterpenoid hybrid dimer in preparation of an acetyl-coenzyme A carboxylase inhibitor. The structure of the triterpenoid-diterpenoid hybrid dimer is shown in formulas 1, 2 and 3. The compound is a natural hybrid dimer which is formed by carrying out Diels-Alder addition or Michael addition reaction on lanolin alkane type triterpenes with a unique spiro structure and abietane diterpenes. According to the present invention, the in vitro activity test results show that the compound has significant acetyl-coenzyme A carboxylase 1 (ACC1) inhibition activity, and can be used for preparing drugs for treating ACC1 mediated non-alcoholic steatohepatitis and other related ...
