Volatile constituents and antimicrobial activity of vinca major l. Subsp. hirsuta (boiss) stearn grown in turkey

Abstract

In this study, volatile compounds (VCs) in the essential oil (EO), SPME and SPME of n-hexane extract of Vinca major subsp. hirsuta (Boiss.) Stearn were analyzed by GC-FID/MS instrument. A total of 32, 38, and 26 compounds with in the 98.5%, 98.6%, and 98.6% were identified, respectively. As a result of VCs study, (Z)-3-hexenol (36.8%) in the EO, 1,3,5-trimethylbenzene (31,5%) in the SPME, and phenylethyl alcohol (32.8 %) in the SPME of n-hexane extract of V. major subsp. hirsuta were found to be major compounds. Sesquiterpenes (20.6%, and 11.5%) for the HD and SPME, monoterpenes (18.6%) for the SPME of n-hexane extract of V. major subsp. hirsuta were found as the main groups among the terpenic compounds, respectively. Then, the antimicrobial activity of the EO and the solvent extracts (n-hexane, acetonitrile, methanol, and water) of V. major subs. hirsuta against 3 gram negative, 3 gram positive, 1 tuberculosis and 2 fungus were screened. The EO showed the only activity against the Mycobacterium smegmatis ATCC607 (MIC, 152 µg/mL) and Candida albicans ATCC60193 (MIC, 38 µg/mL). The n-hexane extract did not show any activity against all tested microorganisms. The best antimicrobial activity for the acetonitrile, methanol, and water extracts were observed against M. smegmatis with 69 µg/mL, 609 µg/mL, and 437 µg/mL MIC values, respectively. None of the extracts were found to be active to Enterococcus faecalis ATCC29212, Staphylococcus aureus ATCC25923, and Saccharomyces cerevisiae RSKK 251.
