Pomegranate Extract Buyer's Guide: Ellagic Acid, Specs & Sourcing

What Pomegranate Extract Is

Pomegranate (Punica granatum) yields several different extracts depending on the part of the fruit used. The high-value B2B ingredient is a peel / pericarp (hull) extract standardised to ellagic acid and punicalagins — the tannin-derived polyphenols that drive most of the published research. A separate class of "pomegranate extract" is made from the fruit, juice or arils and is rich in anthocyanins (the red pigments) but comparatively low in ellagic acid.

This is the single most important fact for a buyer: two products can both be labelled "pomegranate extract 40%" yet differ completely in chemistry, colour and function. The peel extract is the one standardised to ellagic acid; the fruit/juice powder is not. We cover this in depth in peel extract vs fruit powder & adulteration.

Source: Peel vs Fruit

For a standardised ellagic-acid ingredient, specify peel/pericarp extract explicitly. The pomegranate hull is where punicalagins — the largest pomegranate tannins — are concentrated, and on hydrolysis these release ellagic acid. A credible CoA will name the plant part (peel / pericarp), not just "Punica granatum 40%."

The Specification That Matters

The headline assay is ellagic acid, but a complete spec covers physical, residual and contaminant parameters too. The table below reflects SV Botanica's standard 40% grade. Because pomegranate peel extract is a botanical (not an isolated molecule), these figures are typical specifications — a batch-specific Certificate of Analysis is issued with every shipment.

The material is solvent-extracted, non-irradiated and GMO-free, with a 24–36 month shelf life when stored cool and dry. For how the assay is run and why the method changes the headline number, see ellagic acid HPLC vs UV testing.

What a Complete Certificate of Analysis Must Show

Before you qualify any pomegranate supplier, insist on every line below:

• Identity — botanical name (Punica granatum), plant part (peel / pericarp), and HPLC identification against an ellagic acid reference standard.
• Assay with method stated — ellagic acid % by HPLC, and whether any punicalagin figure is by UV or HPLC, so the two are not conflated.
• Physical parameters — appearance (tan to brown, not red), loss on drying, particle size / mesh, solvent residue.
• Heavy metals by ICP-MS — lead, arsenic, cadmium and mercury against defined ppm limits.
• Microbiology — total plate count, yeast & mould, and absence of E. coli and Salmonella.
• Status declarations — non-irradiated, GMO-free, allergen and BSE/TSE-free statements, carrier/excipient if any.
• Batch traceability — batch number, manufacture and expiry dates, shelf life.

The Colour Test: A Free Authenticity Check

Genuine pomegranate peel extract standardised to 40% ellagic acid is tan, light-brown or yellowish-brown — not red, pink or burgundy. A deep-red powder indicates an anthocyanin-rich fruit or juice material, which is typically low in ellagic acid and punicalagins. Colour alone is not a substitute for an HPLC assay, but a red "40% ellagic acid" powder should trigger immediate questions.

Sourcing, MOQ and Lead Time

• Origin — Punica granatum peel, extracted and assayed in India with export-ready documentation.
• Documentation per shipment — batch-specific CoA, MSDS, allergen and Non-GMO declarations, BSE/TSE-free statement and Country of Origin certificate.
• Typical terms — 25 kg minimum order, packed in HDPE drums with food-grade PE liners; sample pouches for qualified buyers; standard lead time on the 40% grade.
