A new biflavonyloxymethane from Pongamia pinnata

Area of Science:

• Phytochemistry
• Natural Products Chemistry
• Pharmacology

Background:

• Pongamia pinnata (Family: Fabaceae) is a medicinal plant used in traditional medicine.
• The root bark of this plant is a rich source of bioactive compounds.
• Flavonoids are a class of natural products known for their diverse biological activities.

Purpose of the Study:

• To isolate and characterize new compounds from the root bark of Pongamia pinnata.
• To evaluate the antioxidant potential of the isolated compounds.

Main Methods:

• Phytochemical investigation of Pongamia pinnata root bark extract.
• Structure elucidation using extensive spectral studies, including 2D-NMR.
• In vitro antioxidant activity assays.

Main Results:

• Isolation and identification of a new biflavonoid, karanjabiflavone.
• Identification of a known furanoflavone, pongapin.
• Both karanjabiflavone and pongapin demonstrated significant antioxidant activity.

Conclusions:

• The root bark of Pongamia pinnata is a valuable source of bioactive flavonoids.
• The newly discovered karanjabiflavone possesses notable antioxidant properties.
• These findings support the traditional use of Pongamia pinnata and suggest its potential in developing antioxidant therapies.
