Figure 3. Effect of fungal culture age on ganoderic acids induction by aspirin in Ganoderma lucidum.

Fungal mycelium cultured on PDA for 4–12 days was incubated with 4 mM aspirin for additional 1 day. Fungal biomass (A), lanosta-7,9(11), 24-trien-3α-o1-26-oic acid (ganoderic acid 24) production (B) and total ganoderic acids (total GAs) production (C) by Ganoderma lucidum were determined. The means of three independent samples with standard deviations are presented. *p<0.05, **p<0.01, ***p<0.001 as compared with the control group.
