摘要
The invention is a plant extract preparation which exhibits a direct fungitoxic effect and is prepared from Hedera helix L. One way of preparing it is by homogenizing the above ground part ofH. helix L. in a liquid, extract the homogenate at a temperature below room temperature and centrifuge the extract, homogenizing in water and filtering the extract before centrifugation. Another way of preparing it is to homogenize the above ground parts of H. helix L. in a liquid, the homogenate is extracted and the extract is centrifuged, homogenizing in an extraction agent, extraction at a temperature below room temperature, and after centrifugation, the supernatant is heated at 60 to 90 °C for 5 to 30 minutes, centrifuged and then the organic phase is evaporated. For use, the formulation is diluted with a non-toxic plant diluent in a ratio of 1: 5 to 1:40 (weight / volume), especially water.
