“…A. orientalis is locally known as ʼHavij-e-kohi’(mountain carrot), and it has been used in Iran and Turkey as a flavor, vegetable and salad 1 , 2 , 3 . The essential oil from different parts of A. orientalis contains fenchyl acetate as a major compound 4 , 5 , 6 , while the major constituent in the essential oil of A. persicus was α -thujene 7 . The hexane extract from aerial parts of A. orientalis was found to be rich in phenolic derivatives 8 , and antimalarial and cytotoxic activities of A. persicus extracts were reported 9 .…”

Sesquiterpene Lactones with Astrodaucane Skeleton from Astrodaucus orientalis

et al. 2022

Four sesquiterpene lactones, astrodaucanolide A-D (1-4) with unique structures, toghether with two known phenylpropanoid esters (5 and 6) were isolated from a flower extract of Astrodaucus orientalis. The structures were established by 1D and 2D NMR spectroscopy and high-resolution mass spectrometry (HRESIMS), and the absolute configuration of 1-4 was determined by electronic circular dichroism (ECD). Compounds 1-4 novel architecture represents a new class of sesquiterpenes with new skeleton. A putative biosynthetic pathway for their scaffold is proposed with a germacryl cation as the precursor. The suggested biosynthesis pathway is similar to that of eudesmane sesquiterpenes with a different direction of protonation which then leads to the new skeleton, named astrodaucane by the 1,2-methyl migration.
