Rosemary (Rosmarinus officinalis) is a plant native to the Mediterranean, used for centuries for its aromatic character. Rosemary leaf extract is obtained by processing leaves that are harvested in a suitable season and dried, using a chosen extraction method. There is no single recipe here: it can be produced in water-based, glycerin, ethanol, hydroglycerin, powder or oil-soluble forms. Which form is chosen depends on the sector and the target application. So what is inside this leaf that makes it so versatile?
The Natural Compounds Inside: What Makes Rosemary Valuable?
The rosemary leaf is rich in various bioactive compounds. The main ones are phenolic compounds, flavonoids, rosmarinic acid, carnosic acid, carnosol and essential oil components. One study examined the phenolic profile of a rosemary extract and identified carnosic acid as the predominant phenolic compound. This group of compounds makes rosemary a plant noted for its antioxidant properties; indeed, a review notes that rosemary extract has been evaluated as a natural option that could replace synthetic antioxidants in foods. It is this profile that makes rosemary extract a sought-after raw material in cosmetics, food and pet products alike.
