Abstract
Antifungal activities of seven compounds, taxinine (1), paclitaxel (2), phenylisoserine methyl ester (3), sciadopitysin (4), ginkgetin (5), isorhamnetin (6), and quercetin (7), isolated from the leaves of kyaraboku, Taxus cuspidata var. nana, against five plant pathogenic fungi, Gibberella fujikuroi, Cladosporium cucumeninum, Fusarium oxysporum, Colletotrichum fragariae, and Corynespora cassiicola, were investigated for utilization of extractives from trees of the genus Taxus. Also, the amounts of compounds 2 and 3 on the leaf surface was measured in relation to the antifungal activities of compounds. Taxinine (1) showed antifungal activity against G. fujikuroi, C. cucumeninum, F. oxysporum, and C. cassiicola. The minimum inhibitory concentration of taxinine for the four fungi was 0.4 μmol. In addition, from the results of antifungal tests, it may be concluded that paclitaxel on the leaves and stem of T. cuspidata var. nana does not play an important role as an antifungicide in the resistance of trees to plant pathogenic fungal attack.
