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. The results

of the tests, scavenging activity DPPH lC50 15.08±1.28 (μg mL-1), FRAP 1.81±0.27 mmol TE g-1 extract, CUPRAC

5.57±0.20 mmol TE g-1 extract and TEAC ise 3.30±0.33 lC50 (μg mL-1) was determined. Total phenolic and total

flavonoid was determined to be extracted content 131.34±8.39 mg GAE g-1 of extract and 35.05±2.82 QA g-1

respectively.

Salvia tomentosa Mill’in Antifungal ve Antioksidant Aktivitesinin Belirlenmesi

Öz

Bu çalışma, Salvia tomentosa’nın antifungal ve antioksidant aktivitesi belirlenmesi amacıyla yürütülmüştür.

Salvia tomentosa’nın uçucu yağı bitki patojeni fungus olan, Rhizoctonia solani ve Alternaria solani ‘nin miselyum

gelişim sırasıyla % 40.63 ve % 60.13 engellemiştir. Antioksidan kapasitesini belirlemek için, Serbest Radikal

Giderme (DPPH), Demir İndirgeme Gücü (FRAP), Bakır İndirgeme Gücü (CUPRAC) ve Serbest Katyon Radikali

Giderme (TEAC) antioksidan aktivite testleri ile Toplam Fenolik (TP) ve Toplam Flavonoid (TF) miktarı analizleri

yapılmıştır. Yapılan antioksidan testleri sonucunda, DPPH lC50 15.08±1.28 (μg mL-1), FRAP 1.81±0.27 mmol TE g-1

eksrakt, CUPRAC 5.57±0,20 mmol TE g-1 ekstrakt ve TEAC ise 3.30±0.33 lC50 (μg mL-1) olarak belirlenmiştir.

Toplam fenolik ve toplam flavanoid içeriği sırasıyla 131.34±8.39 mg GAE g-1 ekstrakt ve 35.05±2.82 mg QE g-1

ekstrakt olarak tespit edilmiştir.
