Abstract
From the petrol ether and chloroform extracts of Polygala paniculata L. (Polygalaceae), possessing both molluscicidal and antifungal properties, four
coumarins were isolated by flash chromatography and centrifugal thin-layer chromatography.
They were identified as aurapten, phebalosin, murrangatin and 7-methoxy-8-(l,4-dihydroxy-3-methyl-2-butenyl)coumarin,
a new natural product. Among these compounds phebalosin showed biological activity,
but proved to be very unstable in aqueous solution.
