Bioactive phenylpropanoids from Daucus crinitus Desf. from Algeria.

Area of Science:

• Phytochemistry
• Natural Product Chemistry
• Pharmacology

Background:

• Daucus crinitus Desf. is a plant species found in Algeria.
• Phenylpropanoids are a class of organic compounds found in plants.
• The chemical composition and biological activities of Daucus crinitus essential oil are not well-documented.

Purpose of the Study:

• To analyze the volatile constituents of Daucus crinitus Desf. from Algeria.
• To synthesize and identify new phenylpropanoid esters.
• To evaluate the biological activities of the essential oil and its constituents.

Main Methods:

• Gas chromatography (GC) and Gas chromatography-mass spectrometry (GC-MS) were used for chemical analysis.
• Chemical synthesis was employed to create homologous esters.
• In vitro assays were performed to assess antibacterial, antifungal, antimalarial, and antiradical activities.

Main Results:

• Isochavicol isobutyrate (39.0%) was identified as the main constituent of the essential oil.
• Isochavicol propionate, a previously undescribed natural product, was identified.
• The essential oil, its esters, and isochavicol exhibited antibacterial and antifungal properties.
• Isochavicol demonstrated significant antiplasmodial activity.

Conclusions:

• The study elucidated the volatile composition of Daucus crinitus essential oil.
• New phenylpropanoid esters were identified, expanding knowledge of natural products.
• The findings highlight the potential therapeutic applications of Daucus crinitus constituents, particularly isochavicol, in combating microbial infections and malaria.
