| Popis: |
The growth inhibiting effect of four commercially available grapefruit seed extracts on the causal organism of apple scab Venturia inaequalis was tested. Germination of the conidia of Venturia inaequalis was pronouncedly inhibited by all tested extracts. The commercial products were analyzed by high pressure liquid chromatography and thin layer chromatography. All samples contained at least one preserving agent. These substances were identified as either benzethonium chloride, benzalkonium chloride, methyl parabene or propyl parabene. Freshly prepared extracts from seeds of grapefruits (Citrus paradisi) did not inhibit the germination of Venturia inaequalis. It was therefore concluded that the antifungal effect of grapefruit seed extracts is caused by the added preservatives. |
