The alkaloid fuyuziphine was isolated from the whole plant of Fumaria indica. It had inhibitive effect against spore germination of some plant pathogenic fungi (Collectotrichum sp., C. gloeosporioides, C. falcatum, Curvularia maculans, C. lunata, Erysiphe cichoracearum, Helminthosporium pennisetti, Oidium erysiphoides, Ustilago cynodontis, Alternaria chieranthi, A. mel-ongenae, A. brassicicola and A. solam). Curvularia lunata, Oidium erysiphoides, Alternaria brassicicola and A. solani did not germinate at 750 and 1000 ppm and Colletotrichum gloeosporioides, C. falcatum, Curvularia maculans were inhibited at 1000 ppm for 24 hr incubation. Germination of most fungi was significantly inhibited at $100{sim}750ppm$.
