Antimicrobials to Prevent Biodeterioration of Grains 101change in protein and carbohydrate content was observed in the grainstreated with 1000 and 1500 ppm even after 4 months of storage, suggestingthat the active compound, 2H-furo[2,3-H]-1- benzopyran-2-one isolated fromseeds of P. corylifolia L. could be exploited to prevent the biodeterioration ofgrains.Potential of 2-hydroxy-4-methoxybenzaldehyde isolated from Decalepishamiltonii Wight & Arn. to prevent biodeterioration of paddyDecalepis hamiltonii Wight & Arn., a member of the family Asclepiadaceae, isan important medicinal plant widely used in traditional medicine. Therhizome (Fig. 4.6) of this plant is largely used in South India for pickling.An antifungal activity assay of different solvent extracts of the freshrhizome of this plant revealed highly significant activity in the petroleumether extract against seed-borne fungal pathogens (Mohana et al., 2006). Furtherexperimentation conducted to isolate and characterize the antifungalactive principle from the petroleum phenolic fraction using chloroform as aFig. 4.6.
