1. Product Introduction
Rosemary is a perennial natural spice plant native to Europe and the North African Mediterranean coast, widely cultivated as a high-value cash crop in Southern Europe. It is one of the earliest medicinal plants discovered and applied globally, with safe and reliable natural activity.
Rosmarinic acid is a characteristic natural phenylpropanoid compound, initially discovered and isolated from rosemary. It is also widely distributed in natural plants such as Prunella vulgaris and Perilla, and can be produced via artificial synthesis as well. Our Rosmarinic Acid Powder features a unique pure herbal aroma with a refreshing sensory effect. The finished product is extracted through mature and stable processes including ethanol extraction, methanol extraction and supercritical carbon dioxide extraction, with pure texture, stable activity and high safety.
2. Molecular Structure & Solubility Characteristics
Molecular Structure: Structurally, rosmarinic acid is a stable ester compound formed by the condensation reaction of one molecule of caffeic acid and one molecule of danshensu (tanshinol), with unique phenolic active structure and excellent physiological activity.
Solubility Properties: It has good water solubility and temperature-dependent solubility, showing higher solubility in hot water than cold water. Besides water, it is also freely soluble in conventional organic solvents such as ethanol and methanol, facilitating diversified formula processing and industrial application.

4. Core Functions & Physiological Efficacy
Rosmarinic acid is the core active ingredient of rosemary extract, synergistically functioning with internal flavonoids, carnosic acid, carnosol and rosmarinol. It integrates antioxidant, anti-inflammatory, antibacterial, anti-allergic and neuroprotective effects, with multi-dimensional health care and medicinal value:
1. Powerful Antioxidant & Skin Care Effect
Rich in high-activity antioxidant components, rosmarinic acid can efficiently scavenge free radicals in the human body, reduce oxidative stress damage, and delay cell aging. Its generated phenolic oxygen free radicals feature stable properties and slow lipid reaction speed, which can block free radical chain reaction and inhibit skin and tissue oxidation. It effectively improves skin texture, repairs damaged skin, and assists in improving skin inflammation and oral ulcers, being a premium natural antioxidant raw material.
2. Antibacterial, Anti-Inflammatory & Respiratory Protection
It has broad-spectrum antibacterial and antiviral activity, capable of inhibiting the growth and reproduction of various harmful bacteria and viruses. It is widely used for relieving respiratory discomforts such as colds, bronchitis and respiratory inflammation, effectively soothing respiratory tract irritation and improving related inflammatory symptoms.
3. Significant Anti-Allergic Activity
Verified by academic research published in Biological Factors, rosmarinic acid combined with natural flavonoids can significantly relieve allergic symptoms. It effectively improves nasal itching, watery eyes, eye itching and other discomforts caused by pollen, dust and external irritation, and comprehensively regulates physical allergic reactions.
4. Cardiovascular & Cerebrovascular Protection
As a natural vascular protective ingredient, rosmarinic acid can improve blood circulation, inhibit vascular oxidative damage, reduce vascular lipid deposition, and effectively prevent and assist in improving various cardiovascular and cerebrovascular sub-health problems.
5. Neuroprotection & Anti-Dementia Effect
It can effectively protect nerve cells, inhibit neurodegeneration, and prevent and improve Alzheimer's disease. A 2020 human clinical study confirmed that daily supplementation of 500mg rosmarinic acid can effectively delay the progression of Alzheimer's disease and protect human neurological health.
5. Wide Application Fields
1. Food Industry & Food Additives
As a natural flavoring agent and food preservative, rosmarinic acid powder can inhibit food oxidative deterioration and extend shelf life. It was firstly researched and applied in the United States and Japan. Japanese food industry widely adopts 95% rosemary acetic acid extract as a safe food additive, which is suitable for various processed foods requiring anti-oxidation and fresh-keeping.
2. Cosmetic & Personal Care Industry
Relying on excellent antioxidant, antibacterial and anti-inflammatory effects, it is added into facial care products, skin repair essences and other cosmetics. In addition, it is widely used in herbal shampoos and scalp care products to improve dandruff problems, regulate scalp oil secretion, soothe inflamed scalp, and maintain scalp and hair health.
3. Daily Chemical Industry
With fresh and lasting herbal aroma and antibacterial and insect-repellent effects, it is widely used in perfumes, soaps, rosemary essential oil, air fresheners, insect repellents and other daily chemical products, balancing fragrance retention and functional care.
4. Nutraceutical & Pharmaceutical Industry
