What is Rosmarinic Acid?

Rosmarinic Acid is a natural polyphenolic compound known for its antioxidant and anti-inflammatory properties. It is commonly used in pet nutrition, animal health products, and dietary supplements. This compound is found in several plants of the Lamiaceae family, such as rosemary (Rosmarinus officinalis), lemon balm (Melissa officinalis), sage (Salvia officinalis), basil (Ocimum basilicum), and perilla (Perilla frutescens). Rosemary extract is the most popular commercial source because rosemary contains high concentrations of rosmarinic acid, provides a stable raw material supply, and allows efficient large-scale extraction. This makes it ideal for mass production. Rosmarinic Acid has the CAS number 20283-92-5 and is also known as alpha-O-caffeoyl-3,4-dihydroxyphenyllactic acid. Its molecular formula is C18H16O8, and its molecular weight is 360.31 g/mol. Commercial Rosmarinic Acid Powder is typically available in 5%, 10%, 20%, and 30% specifications. It appears as a light brown powder, is partially soluble in water, and has good bioavailability in standardized extracts. Standard bulk packaging is 25 kg per drum with food-grade inner bags for safe transport and storage. JaYoo Biotech is a leading bulk Rosmarinic Acid Powder manufacturer in China, supplying high-quality rosemary extract ingredients to global pet supplement brands, animal nutrition companies, and ingredient distributors. The company also provides OEM services, including capsules, tablets, and customized formulations.

Flow Chart of Rosmarinic Acid Manufacturing Process

JaYoo Biotech produces high-quality Rosmarinic Acid Powder from Rosemary Extract (Rosmarinus officinalis) using a controlled extraction and purification process for pet nutrition, animal health, and dietary supplements.

Each batch undergoes comprehensive quality testing, including HPLC assay, heavy metals analysis, and microbiological evaluation, to ensure compliance with international standards. The final product is packaged for global distribution. JaYoo Biotech’s process delivers a pure, safe, and consistent ingredient that meets international and third-party quality requirements. Standard grades (5%, 10%, 20%, and 30% Rosmarinic Acid) are available, and custom specifications can be tailored to your formulation needs, supporting OEM capsules, tablets, and other specialized products.
