Phellibaumin

Phellibaumins are hispidin derivatives made by the fungus Phellinus. Five such derivatives have been identified, known as Phellibaumin A through E. Phellibaumins A and B are classified as pyranones, while Phellibaumins C, D, and E are classified as styrylpyranones.

Phellibaumin A was also identified as being produced by the fungus Inonotus hispidus, and Phellibaumins B and C were identified in Sanghuangporus vaninii. Phellibaumin E is of interest to medical researchers due to potential anti-dementia effects.
