An overview on chemical profile for oil and alcholic tinctures of Rosmarinus Officinalis plants

Pharmaceutical and Natural Sciences

Description

This study shown data on chemical profile for oil and alcoholic tinctures of Rosmarinus officinalis cultivated populations from Durres area. Rosemary is an essential perennial aromatic, evergreen shrub belonging to the family Lamiaceae and indigenous to the Mediterranean region. This plant has branches full of green leaves that exude a characteristic fragrance. For this is widely used in culinary. Rosemary is used since ancient times in traditional medicine because of its vital health effects. Rosemary is a popular and versatile, medicinal plant, and is often used in tinctures and other home remedies. It can be used to treat respiratory infections, digestive issues, and skin irritation. Rosemary tincture believed to improve cognitive function and memory. Rosmarinus Officinalis cultivated plants from Durres area (Lalzi Bay) were taken in January 2025. Plant samples, branches with their leaves, were used for the preparation of oil and alcoholic tinctures of rosemary. After six weeks tinctures were subjected of gas chromatography analyzes for identification of their chemical profile. The rosemary tinctures were injected directly in a Varian 450 GC equipped with flame ionization detector. VF-1ms capillary column (30 m x 0.33 mm x 0.25 um) were used for separation of its compounds. The chemical profile of tinctures were compared with essential oil of the same rosemary samples by using Clevenger apparatus, recommended by Pharmacopoeia. The profile of oil tincture was: Camphor > Cineol > alpha-Pinene > Verbenone while the profile of alcoholic tincture was: Cineole > alpha-Pinene > beta-Pinene > Camphour. The profiles of both tinctures contain the main compounds found in the essential oil of Rosmarinus officinalis but the use of oil and ethanol makes them selective solvents for some individuals: oil for Camphor and Ethanol for Cineole. Chemical profile of tinctures may be of interest in terms of the active compounds they contain.
