WebThis species belongs to the Oecophoridae, and is a specialist feeder on three genera of furanocoumarin-containing Apiaceae. It is highly tolerant to these compounds, and metabolizes them not just by opening the furan ring; in the case of sphondin, it is also capable of O-demethylation ( Nitao et al., 2003 ). The furanocoumarins, or furocoumarins, are a class of organic chemical compounds produced by a variety of plants. Most of the plant species found to contain furanocoumarins belong to a handful of plant families. The families Apiaceae and Rutaceae include the largest numbers of plant species that contain furanocoumarins. The families Moraceae and Fabaceae include a few widely di… WebDec 3, 2024 · A series of novel biphenyl-furocoumarin derivatives were synthesized based on the nuclear structure of imperatorin and identified by IR, ¹H NMR, ¹³C NMR and MS, … highly rated soap making supplies
