Harvested H. jecorina mycelia were ground into fine powder and resuspended in water (0.3 g mycelia/mL). The suspension was sonicated using a Sonifier ® 250 Cell Disruptor (Branson) (power 70%, duty cycle 50%, power for 1 min, 1 min pause, 3 cycles). Insoluble compounds were separated using centrifugation (10 min, 13000 g, 4°C), and the supernatant was analyzed using HPLC-MS/MS.
