Abstract:
Chemical investigation of the endophytic fungus, Trichoderma erinaceum, isolated from healthy and asymptomatic common bean field crop, resulted in the isolation of a new alkene, (Z)-5-amino-5-(1,1,2-trihydroxybuta-1,3-dienyloxy)pentane-6,7,8,9-tetraol (1), together with five known compounds (2-6). The structures of the compounds were elucidated by analysis of their spectroscopic data including 1 D, 2 D NMR, ESI-HRMS and literature data. The organic crude extract and the compound isolated from T. erinaceum significantly (p ≤ 0.05) inhibited the mycelial growth of Pythium ultimum.
