Pine nut shells Extract

Siberian pine seed shell supercritical CO₂ extract (Pinus sibirica) represents a unique valorization of nut processing byproducts, yielding an olive-green oleoresin rich in bioactive diterpenoids and essential fatty acids.

Functional Properties

Dehydroabietic acid dominates at 30.8%—an abietane diterpenoid with documented antimicrobial, anti-inflammatory, and antioxidant activities. The fatty acid fraction features linoleic acid (26.8%), oleic acid (11.3%), and palmitic acid (4.1%), providing skin-conditioning and emollient properties. The monoterpene fraction (α-pinene 4.2%, carveol 3.1%) contributes characteristic coniferous, resinous aroma. Additional diterpenoids—dehydroabietol (3.2%), dehydroabietal (3.7%), and cembrene (1.9%)—enhance the bioactive profile.

Quality

Standardized diterpenoid content verified by GC-MS. Supercritical extraction ensures solvent-free processing. Heavy metals and microbial contamination comply with food-grade specifications.
