Isolation of a Phytoalexin from Pisum sativum L.


THE presence of an antifungal ‘principle (or principles)’ produced by pods of Phaseolus vulgaris L. in response to infections with Sclerotinia fructicola (Wint.) Rhem. has been demonstrated on the basis of biological assays by Muller1,2. We now report the isolation of an antifungal compound produced in similar hypersensitivity studies using pods of Pisum sativum L., and describe some of its chemical, physical and biological properties.
