ABSTRACT

Pongamia pinnata Linn. (Aka Karanja in Ayurveda) is a glabrous tree and a traditionally used medicinal plant found throughout the India. It is commonly used in Ayurveda and has an immense potential in treating various skin diseases viz. piles, ulcers, leukoderma, leprosy and also useful in wound healing. The active principle responsible for the curative action is Karanjin. A preliminary attempt has been done in the present study for the extraction and physicochemical evaluation of Karanjin from plant „Pongamia pinnata,‟ family Fabaceae. The seed oil was subjected to liquid-liquid extraction using organic solvents and Karanjin was identified by TLC, UV Spectroscopy and IR spectroscopy. TLC showed Rf value of 0.35 & 0.34 for methanolic & ethanolic extracts respectively. The experimental frequencies obtained from FTIR analysis have been compared with IR, and the findings for isolated Karanjin were in good compliance with reported values.
