In vitroantioxidant and antimicrobial activity ofCannabis sativaL. cv Modified Letter Turned CommaFutura 75' essential oil

In the present work,Cannabis sativaL. cv Futura 75 inflorescences, cultivated in the Abruzzo territory, were characterized for their volatile fraction through SPME-GC-MS. In addition, the essential oil extracted from these inflorescences was investigated for the antioxidant potentialities and for the terpenic profile. The antibacterial activity of hemp essential oil (HEO) against some pathogenic and spoilage microorganisms isolated from food was also evaluated by determining the minimal inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC). The results showed significant antioxidant capacity (DPPH: 63.38 +/- 0.08 mg TE/g HEO; FRAP: 438.52 +/- 6.92 mg TE/g HEO) alongside good antibacterial activity against Gram-positive bacteria such asS. aureusandL. monocytogenes(MIC 1.25-5 mu L/mL). The results obtained suggest that hemp essential oil can inhibit or reduce bacterial growth, also exerting antioxidant activity, and therefore it can find an advantageous application in the food processing field.

Automated summary

This study found that hemp essential oil has significant antioxidant capacity and good antibacterial activity, especially against certain Gram-positive bacteria.
