Petroselinic Acid

Petroselinic Acid, with the CAS number 593-39-5 and molecular formula C₁₈H₃₄O₂, is a naturally occurring monounsaturated fatty acid classified as a positional isomer of oleic acid. Its defining structural feature is a double bond located at the 6,7-position, which distinguishes it from oleic acid (with a double bond at 9,10-position) and endows it with unique physical and biological properties.
This uncommon fatty acid is primarily isolated from the seed oils of plants belonging to the Apiaceae (Umbelliferae) family, with coriander (Coriandrum sativum) fruits being one of the most abundant sources—its content in coriander seed oil ranges from 31% to 75%. It is also a major fatty acid component in seed oils of other Apiaceae plants, such as fennel and aniseed; for instance, it constitutes up to 46.60% of Tunisian aniseed oil and 38.40% of Egyptian aniseed oil. Additionally, trace amounts have been identified in the Araliaceae plant family.
Commercially, Petroselinic Acid is typically extracted from plant seeds via methods like twin-screw extrusion, followed by purification to meet application-specific standards (e.g., ≥98.0% purity for 科研 use). In its pure form, it appears as a colorless to light yellow liquid with a density of 0.899 g/cm³ and a melting point of 30°C—significantly higher than oleic acid’s 14°C, a difference attributed to its distinct double bond position. As an endogenous human metabolite, it also exhibits oral bioactivity, expanding its potential for dietary and pharmaceutical applications.

Naturally Sourced and Sustainable: Derived primarily from renewable plant seed oils (e.g., coriander), aligning with eco-friendly development needs and reducing reliance on synthetic alternatives.
Distinct Physicochemical Traits: Boasts a melting point of 30°C and stable liquid state at room temperature, with good solubility in DMSO (≥100 mg/mL) and compatibility with various formulation systems.
Broad-Spectrum Biological Activity: Exhibits inherent antibacterial, antifungal, and anti-inflammatory properties, with documented effects on inhibiting microbial biofilms and regulating metabolic pathways.
Low Cytotoxicity: Demonstrates minimal toxicity to mammalian cells (e.g., no obvious harm to HUVEC cells at 64 μg/mL), enhancing its safety for cosmetic and pharmaceutical use.
Modifiable Structure: Serves as a versatile precursor for chemical derivatization, enabling the synthesis of specialized compounds like sophorolipid derivatives and surfactants.

Customers interested in Petroselinic Acid often explore other specialized fatty acids and bioactive lipids in the same research and application domains. Key related products include oleic acid (its well-known positional isomer, widely used in cosmetics and oleochemistry), linoleic acid (a polyunsaturated fatty acid common in plant oils for skin care), sophorolipids (biosurfactants synthesized using Petroselinic Acid as a substrate), and palmitic acid (a saturated fatty acid used in combination with Petroselinic Acid in cosmetic formulations). Additionally, bioactive lipid precursors like adipic acid (for nylon synthesis) and PPAR alpha activators (for dermatological research) are frequently sought after in parallel.
