摘　　要：通过万寿菌根部生物碱类提取物对西瓜枯萎病菌抑制作用的研究,结果表明,在万寿菊根中分离出5类具有抑菌活性的生物碱,其中水溶性生物碱对西瓜枯萎病菌菌丝生长有较好的抑制作用。This research mainly takes watermelon fusarium wilt as the research object, which does serious harm to melon species. The alkaloid from Togetes erecta root was extracted with the method of dissolved with .acid and sunk with alkali. And alkaloid bacteriostasis active constituent from Tagetes erecta root was isolated and purified with thin-layer chromatography, the column chromatographic onalysis and some other biochemical methods. Then we exhaustively carried on the concrete classification and the researeh on alkaloid bacteriostasis material. The result indicated the alkaloid from Tageetes erecta root had many bioactive components against watermelon Fusarium wilt. By separating the alkaloid, we obtained five components of alkaloid. And Water- soluble alkaloid had the best inhibiting effect against Fusarium wilt.
