Product Description

Natrual Plant Extract Antioxidant Rosemary Leaf Extract Powder Carnosic Acid 10%~98% CAS 3650-09-7

Carnosic acid (CA) is a naturally occurring phenolic diterpene found predominantly in the leaves of the rosemary plant (Rosmarinus officinalis) and common sage (Salvia officinalis), both belonging to the Lamiaceae plant family . It is a bioactive compound responsible for many of the health benefits attributed to these herbs.
Carnosic acid exhibits a wide spectrum of pharmacological activities, making it a compound of significant interest for health and industry.

Carnosic Acid's primary and most well-known function is as a powerful antioxidant. The molecule contains a catechol moiety (two adjacent hydroxyl groups on its aromatic ring), which is crucial for its ability to scavenge free radicals and prevent oxidative damage . This property underpins its use as a natural preservative in food and cosmetics.
