Özet

Volatile organic compounds (VOCs) of essential oils (EOs) and solid phase microextract (SPME) obtained from the flower, leaf, and stem of Epilobium angustifolium L. were analyzed by GC-FID/MS. The EOs and SPMEs consist mainly of monoterpenes and aldehydes, which are major classes of compounds. Limonene was found to be a major compound in flower (HD: 42.9% vs. SPME: 95.5%), in leaf (HD: 60.3% vs. SPME: 4.7%), and in stem (HD: 49.06% vs. SPME: 93.6%). The antimicrobial activity of EOs and the solvent extracts (n-hexane, acetonitrile, and methanol) of E. angustifolium were screened in vitro against nine microorganisms. The EO of the leaf showed the best activity (10.2 µg/mL MIC) against Mycobacterium smegmatis. All the EOs and the solvent extracts gave moderate activity against the Staphylococcus aureus, Bacillus cereus, and M. smegmatis within the range of 10.2-1300.0 µg/mL MIC values. The best antibacterial activity was observed against S. aureus and B. cereus in the n-hexane extract of stem and methanol extract of flower samples.
