Summary
A novel coumarin derivative was identified in Sophora japonica roots. Structural analysis revealed its near-planar coumarin core and specific substituent arrangements, with molecules forming hydrogen-bonded chains in the crystal lattice.
Area of Science:
- Natural Product Chemistry
- Organic Chemistry
- Crystallography
Background:
- Sophora japonica is a plant source of various bioactive compounds.
- Coumarin derivatives exhibit diverse pharmacological properties.
- Understanding the structure of natural products is crucial for drug discovery.
Purpose of the Study:
- To isolate and characterize a coumarin derivative from Sophora japonica roots.
- To elucidate the molecular structure and crystal packing of the isolated compound.
Main Methods:
- Isolation of the coumarin derivative from plant extracts.
- Single-crystal X-ray diffraction analysis to determine molecular structure.
- Analysis of intermolecular interactions, including hydrogen bonding.
Main Results:
- A coumarin derivative with the chemical formula C15H16O5 was successfully isolated.
- The coumarin core was found to be nearly planar (r.m.s. deviation of 0.0356 Å).
- The 3-methyl-but-2-en-yloxy group exhibited disorder, and crystal structure revealed O-H⋯O and C-H⋯O hydrogen bonds forming chains.
Conclusions:
- The study successfully identified and structurally characterized a new coumarin derivative from Sophora japonica.
