Content of Carnosic Acid, Carnosol, Rosmarinic Acid, and Proximate Composition in an Assortment of Dried Sage (Salvia officinalis L.)
Year: 2025
Type: article
Abstract: Due to the content of carnosic acid (CA), carnosol (C), and rosmarinic acid (RA), sage (Salvia officinalis L.) has antioxidant, anti-inflammatory, anticancer, antidiabetic, neuroprotective, antiaging, antimicrobial, and antiviral properties. However, current standardization and quality assessment procedures do not specify the content of these key substances in dried sage. The aim of this study was to analyze polyphenolic components, including CA, C, and RA, as well as basic nutrients, such as protein, fat, carbohydrates, and ash content in dried Salvia officinalis. Thirteen products available for sale in Poland were analyzed. HPLC studies have shown a very large variation in terms of CA, C, and RA (CA: 1.25–32.42 mg/g, C: 0–9.06 mg/g, and RA: 3.2–20.6 mg/g). Similarly, significant differences between samples were observed for the proximate composition. An appropriate system of standardization of herbs and spices could ensure the repeatability of the concentration of key, non-volatile active substances, which in adequate doses may have a beneficial effect on certain body functions, as well as on the shelf life and sensory characteristics of food.
