1. The water-soluble leaf extracts from 61 plant species in 32 families were screened for their ability to inhibit two hydrolytic fungal enzymes, cellulase and pectinase. 2. Leaf extracts from 29 species inhibited pectinase and extracts from 14 inhibited cellulase. 3. The leaves from muscadine grape, persimmon, dogwood, blueberry, sericea, blackberry, raspberry, and rose were considered good sources for the pectinase inhibitor as measured against cucumber-flower pectinase and a commercial pectinase. 4. In general, cellulase inhibition by the different plant species was less pronounced than that observed for pectinase. The first five species listed in the previous paragraph gave strong inhibition of cucumber-flower cellulase. Muscadine grape and persimmon were the only two species which inhibited the commercial cellulase enzyme 19AP, and then only moderate to weak inhibition was obtained. |
