New Isoflavones with Antioxidant Activity Isolated from Cornulaca monacantha

Area of Science:

• Phytochemistry
• Natural Products Chemistry
• Pharmacognosy

Background:

• Cornulaca monacantha, a plant from the Amaranthaceae family, is a subject of phytochemical interest.
• Investigating the chemical constituents of medicinal plants can lead to the discovery of novel bioactive compounds.

Purpose of the Study:

• To isolate and characterize new and known phytochemicals from the aerial parts of Cornulaca monacantha.
• To evaluate the antioxidant potential of the isolated compounds.

Main Methods:

• Phytochemical investigation using spectroscopic methods, including one- and two-dimensional Nuclear Magnetic Resonance (NMR) and High-Resolution Electrospray Ionization Mass Spectrometry (HR-ESI-MS).
• Isolation of compounds from fresh aerial parts of C. monacantha.
• Assessment of antioxidant activity using DPPH, ABTS, and Total Antioxidant Capacity (TAC) assays.

Main Results:

• Two new isoflavones, 3-(2-hydroxyphenyl)-5,7-dimethoxy-6-(methoxymethyl)-4H-1-benzopyran-4-one and 7-hydroxy-3-(4-hydroxyphenyl)-5-methoxy-6-(methoxymethyl)-4H-1-benzopyran-4-one, were identified.
• Three known compounds, vanillic acid, N-cis-feruloyltyramine, and N-trans-feruloyltyramine, were also isolated.
• The isolated compounds displayed notable antioxidant activities.

Conclusions:

• The study successfully identified novel isoflavones and known compounds from Cornulaca monacantha.
• The isolated phytochemicals possess significant antioxidant properties, suggesting potential therapeutic applications.
• Further research into the pharmacological activities of these compounds is warranted.
