Chemical content of volatile oil of Primula veris subsp. columnae, obtaining the methanol extracts and their biological activities

Abstract

The proportions and constituents of the essential oils of flowers and leaves of Primula veris subsp. columnae were determined, and the antioxidant and the antimicrobial (antibacterial and antifungal) properties of their methanol extracts were investigated. Percentage ratios and main components of the Primula veris subsp. columnae plant, which grows naturally, were detected by extracting flower and leaf volatile oils. The components of the volatile oil were identified with Gas Chromatography Mass Detector-Flame Ionization Detector (GC-MS/FID). A total of 62 compounds were identified in flower volatile oil, and methyl 4-methoxysalicylate (37.1%) was determined as the main compound. While defining the structure of 50 compounds in leaf essential oil, linoleic acid (40.1%) was established as the main compound. As the result of the extraction of flowers and leaves with methanol, the extractive substance was obtained as 34.5% in flowers and as 28.8% in leaves. Methanol extraction and the antioxidant properties of the Primula veris subsp. columnae plant were quite high. In the antifungal and antibacterial activity test conducted on the volatile oils and methanol extracts of flowers and leaves of the Primula veris subsp. columnae species, only flower volatile oil showed weak inhibition properties.
