3. Analytical Chemistry & HPLC Biochemical Assay
| Active Compound | Fungal Source | Physiological Mechanism |
|---|---|---|
| Hericenones (A–H) | Fruiting Body | Crosses blood-brain barrier to stimulate Nerve Growth Factor (NGF) synthesis. |
| Erinacines (A–I) | Cultured Mycelium | Potent diterpenoid inducers of brain-derived neurotrophic factor (BDNF). |
| 1,3/1,6 Beta-D-Glucans | Cell Wall Matrix | >25% concentration via AOAC 995.16 assay; activates macrophage phagocytosis. |
4. Scientific Questions & Empirical Protocols
How does Lion's Mane stimulate Nerve Growth Factor (NGF)?
Low molecular weight hericenones easily pass through the blood-brain barrier, triggering astrocytes to synthesize endogenous NGF required for hippocampal neurogenesis and synaptic plasticity.
What is the best substrate for cultivating Hericium erinaceus?
The gold standard is Masters Mix: an equal 50/50 dry mass blend of coarse hardwood sawdust (oak or maple) and unpelleted soybean hulls, hydrated to 60% moisture and autoclaved at 15 PSI for 2.5 hours.
