Açaí Pulp Oil (Euterpe oleracea) (Euterpe oleracea)
Preliminary EvidenceCompound
Hermetica Superfood Encyclopedia
Açaí pulp oil contains anthocyanins and oleic acid that provide antioxidant and anti-inflammatory effects through free radical scavenging. Studies show nanoemulsions increase antioxidant activity by 47% compared to pure oil in animal models.
Açaí pulp oil is derived from the fruit of Euterpe oleracea Mart., a palm species native to the Amazon region of South America. The oil is extracted from the berry using methods including supercritical fluid extraction technology, which separates oil-rich and fat-free pulp fractions with high purity. Chemically classified as a polyphenol-rich lipid extract, it contains phenolic acids, flavonoids, anthocyanins, procyanidins, and carotenoids.
The research dossier contains exclusively preclinical and animal studies, with no human clinical trials, RCTs, or meta-analyses documented. All evidence derives from in vitro cell culture experiments and animal models, primarily in rats and mice. No PMIDs were provided in the source material.
Animal studies used oral doses of 500-1500 mg/kg body weight for anti-inflammatory effects and 100 mg/kg for hepatoprotection. In vitro concentrations ranged from 0.04-12 µg GAE/mL for polyphenolic extracts and 1.56-100 μg/mL for oil. No human dosages have been established. Consult a healthcare provider before starting any new supplement.
Açaí pulp oil is a lipid-rich extract with a fatty acid composition dominated by oleic acid (omega-9, approximately 56-62% of total fatty acids), followed by palmitic acid (saturated, approximately 20-25%), and linoleic acid (omega-6, approximately 10-12%), with minor amounts of stearic acid (~1-2%) and alpha-linolenic acid (omega-3, <1%). Total fat content is effectively 100% as it is a refined oil. Notably rich in phytosterols, primarily beta-sitosterol (~76-81% of total sterols), campesterol (~6-8%), and stigmasterol (~4-6%), with total phytosterol concentrations estimated at 1,500-2,500 mg/kg oil. Contains significant tocopherols (vitamin E), predominantly gamma-tocopherol and delta-tocopherol, with total tocopherol content reported in the range of 150-350 mg/kg; alpha-tocopherol is present but at lower concentrations than gamma forms. Rich in polyphenolic compounds, including anthocyanins (cyanidin-3-glucoside and cyanidin-3-rutinoside) and flavonoids, though concentrations are higher in pulp than in refined oil and vary by extraction method. Contains carotenoids (beta-carotene, lutein) at approximately 3-7 mg/kg in cold-pressed preparations. No protein, carbohydrates, or dietary fiber are present in meaningful quantities given its oil form. Bioavailability notes: oleic acid enhances absorption of fat-soluble compounds; phytosterols compete with cholesterol absorption in the gut, potentially reducing LDL cholesterol; tocopherol bioavailability is moderate and influenced by overall dietary fat intake; polyphenol content and bioavailability are highly dependent on extraction method (cold-press vs. solvent extraction), with nanoemulsion formulations shown to significantly improve antioxidant compound delivery (up to 47% greater activity in preliminary models).
Açaí pulp oil's anthocyanins neutralize reactive oxygen species through electron donation, while oleic acid modulates inflammatory pathways. The oil inhibits prostaglandin synthesis by suppressing cyclooxygenase enzymes. Nanoemulsion formulations enhance bioavailability and cellular uptake of active compounds.
Evidence for açaí pulp oil comes primarily from preliminary animal studies. Mouse models demonstrated 47% greater antioxidant activity with nanoemulsions compared to pure oil. Anti-inflammatory effects were observed at doses of 500-1500 mg/kg in animal studies showing prostaglandin synthesis inhibition. Human clinical trials are limited, making evidence strength preliminary.
Açaí pulp oil is generally well-tolerated with minimal reported side effects in studies. No specific drug interactions have been documented, though theoretical interactions with anticoagulants are possible due to oleic acid content. Safety during pregnancy and breastfeeding has not been established. Individuals with palm fruit allergies should exercise caution.
