Novel in-expensive and efficient process for isolation of imperatorin, a potent inducible nitric oxide synthase inhibitor and anti-inflammatory drug candidate from Aegle marmelos Correa

The present invention relates to a process for isolating imperatorin, an anti-first-pass effective low molecular weight linear furanocoumarin from the mature/immature mesocarp fresh/dry Aegle marmelos Correa fruits. Immunologically important phytosterols enriched fraction is a useful by-product of this process, which might enter this new century as therapeutics for targeting specific sites in the immune system.
