MetadataShow full item record
The essential oils from Salvia officinalis L., S. cryptantha (Montbret et Aucher ex Benth.) and S. tomentosa (Mill.) were extracted with hydrodistillation method and determined by using GC/MS analysis. This study investigated the in vitro effectiveness of essential oils and extracts of S. officinalis, S. cryptantha and S. tomentosa (collected from Tokat province) against eight fungal plant pathogens. Sterile PDA was prepared and then cooled to 40 degrees C, after which the plant essential oils and/or extract were added. PDA without extract was used as negative control, while PDA with a Propineb-containing fungicide was used as positive control. According to the GC/MS analysis, the principal components of S. cryptantha, S. tomentosa and S. officinalis essential oils were determined as eucalyptol (27.64%), Camphor (29.87%), a-pinene (11.91%); beta-thujene (40-69%), borneol (1.79-10.90%), camphor (0.40-7.25%); 3-thujonene (31.95%), camphor (28.53%), eucalyptol (7.35%), respectively. Based on the current results, the plant essential oils and extracts were determined to have negative effects on plant pathogens fungi. These effects changed depending on the extract, the type of sage the essential oil/extract that was obtained, the dose of essential oil or extract, and the fungus species.
