Синонимы: Rosmarinic acid, (R)-2-((3-(3,4-Dihydroxyphenyl)-1-oxo-2-propenyl)oxy)-3-(3,4-dihydroxyphenyl)propanoic acid, 3,4-Dihydroxycinnamic acid (R)-1-carboxy-2-(3,4-dihydroxyphenyl)ethyl ester, Rosemary acid, Labiatae acid, C18H16O8

Rosmarinic acid is a naturally occurring phenolic compound extracted from rosemary (Rosmarinus officinalis) and other Lamiaceae herbs. It is supplied as an off-white to light beige crystalline powder, standardized to ≥98% purity by HPLC. This high-purity grade is intended for use as a reference standard, in research formulations, and as a functional ingredient in cosmetic and nutraceutical applications.

As a purified single molecule, it offers consistent potency and predictable behavior in formulation. The compound is soluble in polar organic solvents such as ethanol and methanol, and slightly soluble in water, which guides its incorporation into both anhydrous and aqueous systems. Its stability profile makes it suitable for products where a defined phenolic content is required.

Typical applications include antioxidant capsules and tablets, anti-aging skincare serums and creams, and functional beverages. In these formats, rosmarinic acid serves as a standardized active, often combined with other botanical extracts or vitamins to enhance oxidative stability. The material is also used in laboratory settings as an analytical standard for method development and quality control.

Applications & Formulation Use

In the nutraceutical sector, rosmarinic acid is formulated into capsules and tablets aimed at daily antioxidant support. It blends well with other dry ingredients and can be used in powdered drink mixes where a precise dosage of the active is desired. For cosmetic applications, it is incorporated into emulsions, serums, and creams, where it contributes to product stability and skin conditioning. Formulators appreciate its compatibility with a range of carriers and its low odor, which minimizes impact on final product sensory profile.

Beyond finished products, this grade serves as a reference standard for HPLC and LC-MS analysis, helping quality control laboratories verify the identity and purity of rosemary extracts and other botanical materials. Its well-characterized nature makes it a preferred choice for method validation and routine testing.

Sourcing & Production

Rosmarinic acid is obtained through extraction from rosemary leaves, followed by purification steps including solvent partitioning and crystallization. The process yields a high-purity crystalline powder that meets the ≥98% specification. Production is carried out under controlled conditions to ensure batch-to-batch consistency. The final material is tested for identity and assay before release.
