Polyphenols

The primary active chemistry in the botanical formulation. Mechanistically diverse — different polyphenol classes address different nodes of the cascade.

Classification Relevant to This Protocol

Catechins (Green Tea)

• EGCG (epigallocatechin gallate): logP ~1.5, iron chelation, tocopherol regeneration, moderate fat-phase partitioning
• Caffeine (co-present): logP −0.07 — does NOT partition into fat
• Nrf2 activation, TLR4 modulation

Flavonols

• Quercetin: logP ~1.5–2.0, mast cell calcium channel inhibition, histidine decarboxylase inhibition, beta-glucuronidase inhibition, NF-κB inhibition. Deglycosylated by fermentation beta-glucosidase → free aglycone with higher bioavailability. Capers: highest quercetin concentration of any food (~1700mg/100g).
• Luteolin: more potent mast cell stabilizer than quercetin, better BBB penetration (brain fog relevance)
• Fisetin: senolytic activity (clearing senescent fibroblasts), mast cell effects
• Kaempferol: mast cell stabilization, in dill and many botanical pack ingredients
• Rutin (quercetin-3-rutinoside): specifically in buckwheat honey; most bioavailable quercetin glycoside form; fermentation deglycosylates to free quercetin

Flavones

• Apigenin: GABA-A receptor modulation (anxiolytic + mast cell + sleep), chamomile primary compound
• Baicalin: STAT6 inhibition (IgE class switching suppression), PAD4 inhibition (RA specific), Th17 suppression. Skullcap (Scutellaria). Fermentation pH enhances extraction.
• Chrysin: PDE inhibition pathway for mast cell stabilization; in passionflower and honey

Anthocyanins

• Cyanidin-3-glucoside (tart cherries, red cabbage): COX-2 inhibition, anti-inflammatory
• Specific mast cell stabilizing effects through FcεRI modulation
• Color bodies in the brine — deep purple indicates adequate extraction

Proanthocyanidins / OPCs

• Pine bark (Pycnogenol equivalent): physically bind collagen and elastin fibers, protecting from MMP degradation. Jacques Cartier 1535 CE — historical discovery.
• Grape seed, hawthorn: overlapping but distinct proanthocyanidin profile
• eNOS activation (independent of VEGF pathway, complementary to dan shen)

Secoiridoids (Olive)

• Oleuropein: logP ~1.5–2.0, thermally converts to hydroxytyrosol at frying temperatures
• Hydroxytyrosol: EFSA health claim, NF-κB inhibition, mast cell stabilization via PKC pathway, iron chelation, MMP inhibition

Stilbenes

• Resveratrol: SIRT1 activation, Nrf2, relatively poor bioavailability
• Pterostilbene (methylated resveratrol): logP 3.4, dramatically better bioavailability, longer half-life, better BBB penetration, SIRT1 activation. Preferred over resveratrol.
• Pinosylvin (pine resin): structurally related stilbene, SIRT1 activation, found in pine pitch — the amphora connection

Xanthones (Mangosteen)

• Alpha, beta, gamma-mangostin: extremely potent but narrow availability
• Mentioned for completeness

The Fermentation Bioavailability Enhancement

Lactobacillus beta-glucosidase cleaves glycosidic bonds:

• Quercetin-3-glucoside → quercetin aglycone (2× better absorption)
• Rutin → quercetin aglycone (further enhanced)
• Diosmin → diosmetin (lymphatic activity enhanced)
• Baicalin → baicalein (more active form)

The 120-day fermentation is not just preservation — it is enzymatic bioavailability enhancement. The prepared formulation delivers more bioavailable polyphenols per unit mass than raw botanical material.

LogP and Fat-Phase Partitioning

For in-fryer applications, logP determines whether a polyphenol will transfer into the fat:

• logP > 1.5: meaningful partitioning → effective radical chain terminator in fat phase
• logP ~0–1.5: minimal partitioning → mostly stays in water phase of food
• logP < 0: does not partition into fat

Carnosic acid (logP 4–5) and thymol (logP 3.3) have the best fat-phase partitioning. EGCG (logP 1.5) is marginal but works. Hydroxytyrosol (logP 0.6) is marginal but provides iron chelation benefit.
