Abstract
Plant species that were reported to have fungicidal properties on other fungal genera and have of medicinal value was collected and extracted using water. Crude water extracts of 6 out of 97 plant species screened for their fungicidal properties in vitro showed inhibitory activity against Aspergillus flavus and A. parasiticus.
The crude extracts of garlic (Allium sativum) was found to be the most effective against Aspergillus flavus and A. parasiticus. In their decreasing order the following plant extract; Kalachuchi (Plumiera acuminata) >Bulakmanok (Ageratum conyzoides) > Sampa-sampalukan (Phyllantus nirure L.) while Talisay (Terminalia catappa L.) >Kakawati (Gliricidia sepium Jacq.) were quite effective on Aspergillus flavus and A. parasiticus, respectively. Also, aflatoxin formation was not detected on potato dextrose broth with the above mentioned crude extracts inoculated with aflatoxin-forming organisms.
