Pine

Pine, in the grade Nustras supplies, is pine bark extract: a botanical extract prepared from the bark of the eastern white pine, Pinus strobus, by ethanol and water extraction and supplied as a red-brown fine powder. Pine bark is a concentrated natural source of oligomeric proanthocyanidins (procyanidins), together with catechin and phenolic acids.

Pine bark extract is formulated into botanical supplements in capsule and tablet form, polyphenol and berry blends, powdered drink mixes, functional foods and beverages, and cosmetic and personal-care products where a plant-derived proanthocyanidin source is wanted.

The material is a red-brown fine powder with a mildly astringent taste. The extract is standardised to a minimum proanthocyanidin content determined by UV spectrophotometry; botanical identity is confirmed by HPTLC, and grades are available against USP requirements. Heavy-metal, residual-solvent and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis. The listed origin is China.

Nustras supplies pine bark extract in bulk commercial quantities, in sealed packaging and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Pine bark extract is an accepted supplement and cosmetic ingredient in major markets; buyers confirm the permitted level and claim for their application.
