Sesquiterpene lactones from Anthemis carpatica Willd

Area of Science:

• Natural Product Chemistry
• Phytochemistry
• Organic Chemistry

Background:

• Anthemis carpatica is a plant species known for its potential medicinal properties.
• Sesquiterpene lactones are a diverse class of natural products with various biological activities.
• Previous research has explored the chemical constituents of Anthemis species.

Purpose of the Study:

• To isolate and characterize new chemical compounds from the aerial parts of Anthemis carpatica.
• To elucidate the structures of novel eudesmanolides and guaianolides.
• To identify known sesquiterpene lactones present in the plant.

Main Methods:

• Extraction of secondary metabolites from the aerial parts of Anthemis carpatica.
• Chromatographic techniques for isolation of individual compounds.
• Spectroscopic methods (e.g., NMR, MS) for structure elucidation.
• Comparison with known compounds for identification.

Main Results:

• Isolation and structural determination of four new eudesmanolides.
• Isolation and structural determination of two new guaianolides.
• Identification of seven known sesquiterpene lactones.

Conclusions:

• The aerial parts of Anthemis carpatica are a rich source of structurally diverse sesquiterpene lactones.
• The newly identified compounds contribute to the known chemical diversity of eudesmanolides and guaianolides.
• This study expands the phytochemical knowledge of the Anthemis genus.
