The purpose of this study was to assess the effectiveness of essential plant oils from Vitex agnus-castus L. ), and plant essential oils were applied at concentrations of 0.5, 1, 1.5, 2, 5 and 10 (μL/Petri -1 ) into the 5 mm diameter wells opened on the Petri dish surface. After that, the Petri dishes incubated at 22±2 °C. The results of this study, the essential oil of M. communis, at a dose of 10 μL/ Petri, inhibited the 100% mycelium growth of V. dahliae, S. sclerotiorum and R. solani. The highest dose of VAC essential oil was also 100% inhibited V. dahliae and S. sclerotiorum. The LC 50 and LC 90 values of M. communis and VAC essential oil calculated for V. dahliae, FORL, S. sclerotiorum and R. solani. This plant extracts were shown by in vitro conditions to be potential antifungal agents.

In this study, we researched the chemical composition and the antifungal and antibacterial activity of volatile oil from Mentha spicata. The Gas chromatography/mass spectrometry (GC/MS) analysis of M. spicata showed that the main component was carvone (56.94%), followed by limonene (11.63%), sabinene hydrate (7.04%) and caryophyllene (4.06%). The antifungal activity of the volatile oil from M. spicata L. was determined with respect to plant pathogenic fungi, such as Fusarium oxysporum f. sp. radicis-lycopersici (Sacc.) W.C. Synder & H.N. Hans (FORL), Rhizoctonia solani J.G. Kühn. (R. solani), Alternaria solani (A. solani), and Verticillium dahliae Kleb (V. dahliae). The volatile oil was shown to have strong antifungal activity against plant pathogenic fungi. The result of the study was that at a dose of 12 μL petri-1 , the volatile oil inhibited 100% of mycelium growth in V. dahliae, A. solani FORL and R. solani. Volatile oil exhibited remarkable activity against the selected bacterial strains of Xanthomonas spp. (ZI365,

In this study, was determined antifungal and antioxidant activity of Salvia tomentosa. The essential oil of Salvia tomentosa was determined of the percentages of mycelium inhibition agains plant pathogenic fungi Rhizoctonia solani and Alternaria solani 40.63% and 60.13% respectively. To determine the antioxidant capacity, Free radical reduction (scavenging), iron reduction power (FRAP), copper reduction power (CUPRAC) and free radical cations reduction (TEAC), total phenolic (TP) and total flavonoids (TF) tests were performed.

ÖzDünyada geniş bir alana yayılmış olan Salvia türleri, yüksek antioksidan aktiviteye sahip fenolik madde içeriğinden dolayı tıbbi aromatik bitkiler arasında önemli bir yere sahiptir. Bu çalışmada, Salvia verticillata subsp. amasiaca türünün metanol ekstraktının antioksidan kapasitesini belirlemek için Serbest Radikal Giderme (DPPH), Demir İndirgeme Gücü (FRAP), Bakır İndirgeme Gücü Determination of Antioxidant Capacity and Total Phenolic Matter of Salvia verticillata subsp. amasiaca AbstractSalvia genus, being as widely growed in the world, due to the antioxidant and phenolic content has an important role in medical aromatic plants. In this study, Salvia verticillata subsp. amasiaca of sage species methanol extracts was determined by the total phenolic and antioxidant activity. Free radical reduction (scavenging), iron reduction power (FRAP), copper reduction power (CUPRAC), free radical ctions reduction (TEAC), total phenolic (TP) and total flavonoids (TF) tests were performed. The results of the tests, scavenging activity DPPH lC50 11,47±0,30, FRAP 22,22 ± 0,36 mmol TE/g extract, CUPRAC 6,67 ± 0,16 mmol TE/g extract and TEAC ise 5,77 ± 0,82 lC50 (µg/mL) was determined. Total phenolic and total flavonoid was determined to be extracted content 140,18 ± 8,73 mg GAE / g of extract and 51,56 ± 1,18 QA / g, respectively. As a result of the Salvia verticillata subsp.
