General Description

Karanjin is a natural chemical compound found in the seeds of the karanja tree (Pongamia pinnata). It is a flavonoid and belongs to the class of compounds known as furanoflavonoids. Karanjin has demonstrated various biological activities, including insecticidal and antimicrobial properties. It has been used traditionally as an insect repellant and in traditional medicine for its antibacterial and antifungal properties. In addition, karanjin has shown potential as an eco-friendly alternative to synthetic pesticides, making it a subject of interest for sustainable agriculture and pest control.
