According to a study published by "BMC microbiology", endophytic fungi were isolated from the roots, stems, leaves, and tubers of Pinellia pedatisecta. From the fungus Aspergillus floccosus PP39 of P. pedatisecta, three compounds were isolated, including terreic acid (5), terremutin (6), and citrinin (7). Compound 5 exhibited strong antibacterial activities against Escherichia coli, Micrococcus tetragenus, Staphylococcus aureus, and Pseudomonas syringae pv. actinidiae with inhibition zone diameters of 36.0, 31.0, 33.7, and 40.2 mm. The minimum inhibitory concentration (MIC) values for these bacteria were 1.56, 3.13, 1.56, and 1.56 μg/mL, respectively. Additionally, compound 7 showed strong antibacterial activity against P. syringae pv. actinidiae with an inhibition zone diameter of 26.0 mm and a MIC value of 6.25 μg/mL. Compound 7 also demonstrated potent phytotoxic activity against E. crusgalli with a 73.4% inhibition rate at a concentration of 100 μg/mL.
