Aromaticine, a sesquiterpene lactone from Amblyopappus pusillus
Aromaticine, a natural lactone from Amblyopappus pusillus, has a molecular structure consistent with prior research. Its fused-ring system features a twist-boat seven-membered ring and two trans-fused envelope five-membered rings.
Area of Science:
- Natural Product Chemistry
- Organic Chemistry
- Phytochemistry
Background:
- Aromaticine is a natural lactone isolated from the plant Amblyopussillus.
- The chemical formula is C(15)H(18)O(3).
Purpose of the Study:
- To confirm the molecular structure and conformation of Aromaticine.
- To validate findings with existing literature.
Main Methods:
- Isolation of Aromaticine from Amblyopussillus.
- Molecular structure determination.
- Conformational analysis.
Main Results:
- The molecular structure and conformation of Aromaticine were elucidated.
- The fused-ring system comprises a seven-membered ring in a twist-boat conformation.
- Two five-membered rings are trans-fused in envelope conformations.
Conclusions:
- The determined structure and conformation of Aromaticine align with previous studies by Romo, Joseph-Nathan & Díaz.
- This study provides further characterization of this natural lactone.
