Background:

Evodia lepta is a plant species known for its potential bioactive compounds.
Dichromenes are a class of organic compounds with diverse chemical structures.

Purpose of the Study:

To isolate and characterize new chemical entities from Evodia lepta.
To elucidate the structures of novel dichromenes using advanced analytical techniques.

Main Methods:

Extraction of compounds from the aerial parts of Evodia lepta.
Purification of isolated compounds using chromatographic techniques.
Structure determination via comprehensive spectroscopic analysis (e.g., NMR, MS).

Main Results:

Two new dichromene compounds, designated 1 and 2, were successfully isolated.
The chemical structures of compounds 1 and 2 were unambiguously determined.
The isolation represents a novel contribution to the known secondary metabolites of Evodia lepta.

Conclusions:

The study successfully identified and characterized two new dichromenes from Evodia lepta.
These findings expand the knowledge of natural products derived from this plant species.
Further research may explore the biological activities of these novel compounds.
