Rosmarinic Acid Powder | Natural Antioxidant & Anti-Inflammatory Headline: High-Purity Rosmarinic Acid Manufacturer | 98% Natural Antioxidant (CAS: 20283-92-5) Sub-info: Source: Rosmarinus officinalis (Rosemary) Leaf | Assay: 5% - 98% (HPLC) | Water-Soluble USP: Stronger than Vitamin E • Natural Food Preservative • Anti-Viral & Anti-Allergy
Introduction

Rosmarinic Acid is a naturally occurring water-soluble phenolic compound extracted from Rosemary (Rosmarinus officinalis) or Perilla. It is widely recognized as one of the most potent natural antioxidants available, with radical scavenging activity superior to Vitamin E and Vitamin C.
Unlike oil-soluble antioxidants (like Carnosic Acid), Rosmarinic Acid is ideal for aqueous systems. It is extensively used as a natural preservative in the food industry to extend shelf life and as a bioactive ingredient in pharmaceuticals for its anti-inflammatory and antiviral properties.
quality Rosmarinic acid spots are widely recognized for their strong antioxidant and natural plant extract properties. Derived from herbs such as rosemary and other botanical sources, quality Rosmarinic acid spots are commonly used in pharmaceutical, cosmetic, and food supplement industries. The compound helps protect cells from oxidative stress and supports overall health applications. quality Rosmarinic acid spots also offer anti-inflammatory and skin protection benefits, making them valuable ingredients in skincare formulations. With stable chemical properties and reliable purity, quality Rosmarinic acid spots are suitable for various natural product developments.

Functions
1. Superior Antioxidant Activity Rosmarinic Acid effectively scavenges reactive oxygen species (ROS) and inhibits lipid peroxidation. It is particularly effective in preventing the oxidation of fats and oils in food emulsions and protecting skin cells from UV-induced oxidative stress.

2. Anti-Inflammatory & Anti-Allergy It inhibits the enzymes cyclooxygenase (COX-2) and 5-lipoxygenase (5-LOX), reducing the production of inflammatory mediators. Clinical studies suggest it helps relieve symptoms of seasonal allergic rhinoconjunctivitis (hay fever) by suppressing histamine release.
3. Anti-Microbial & Anti-Viral Exhibits broad-spectrum antimicrobial activity against foodborne pathogens (e.g., Staphylococcus aureus) and demonstrates antiviral effects, making it a valuable natural preservative and immune support ingredient.

Method of Analysis of Lactoferrin
We use HPLC (High-Performance Liquid Chromatography) with UV detection at 330nm.
• Purity Levels: We offer customizable specs:
5% - 20%: For Food Preservation (Cost-effective).
50% - 98%: For Dietary Supplements and Cosmetics (High Potency).
Reference Chromatogram of Lactoferrin Reference Substance
(Imagine a clean HPLC peak) The chromatogram shows a dominant peak at the retention time of Rosmarinic Acid. For the 98% grade, other phenolic components are removed, ensuring a high-purity profile suitable for pharmaceutical research.

Stability and Safety
Stability Studies
• Shelf Life: 24 months.
• Thermal Stability: Rosmarinic Acid is relatively heat stable (up to 200°C short term), making it suitable for baked goods and pasteurized drinks.
• Storage: Store in a cool, dry place away from light. Exposure to high pH (alkaline) can cause degradation.
Safety & Handling (MSDS Summary)
• Classification: Non-hazardous food additive.
• Safety: GRAS (Generally Recognized As Safe). No known toxicity at standard usage levels.
• Handling: Avoid inhalation of fine dust.

FAQ
What is the difference between Rosmarinic Acid and Carnosic Acid?
Both are from Rosemary. Rosmarinic Acid is water-soluble and used in drinks, aqueous foods, and allergy supplements. Carnosic Acid is oil-soluble and used in fats, oils, and fried foods to prevent rancidity.
Can I use it in baking?
Yes. Rosmarinic Acid has good thermal stability and can withstand baking temperatures, making it an excellent natural preservative for cookies and breads.
Is it effective against bacteria?
Yes. It has antimicrobial properties, particularly against Gram-positive bacteria like S. aureus and Listeria, which helps improve food safety.
