Abstract

In the current study, antioxidant activities of the aerial parts and roots of Tragopogon longirostris Bisch. ex Sch. Bip. var. longirostris and T. pratensis subsp. orientalis L. were evaluated. Antioxidant activity of the Tragopogon aqueous methanol extracts were investigated by DPPH scavenging and superoxide anion scavenging assays. Total phenolic and flavonoid contents of the extracts were calculated using Folin-Ciocalteu and aluminum chloride colorimetric methods and determined ranging from 63.45±0.25 to 68.92±0.42 mg/g caffeic acid and from 4±1 to 210±9 mg/g quercetin respectively. Furthermore the phenolic acids; chlorogenic acid, caffeic acid, ferulic acid, rosmarinic acid, p-coumaric acid and flavonoids; apigenin, luteolin, quercetin, hyperoside, rutin, hesperidin in T. longirostris var. longirostris and T. pratensis subsp. orientalis have been determined qualitatively and quantitatively using reverse phase high performance liquid chromatography. Chlorogenic acid was determined in all samples investigated. The highest content of chlorogenic acid was detected in aerial part extract ofT. longirostris var. longirostris as 578.22 ± 4.19 µg/mg.

Özet

Bu çalışmada Tragopogon longirostris Bisch. ex Sch. Bip. var. longirostris ve T. pratensis subsp. orientalis L. bitkilerinin toprak üstü ve köklerinin antioksidan etkileri değerlendirilmiştir. Tragopogon turlerinin sulu metanollu ekstrelerinin antioksidan aktivitesi DPPH ve superoksit anyon supurucu aktivite testleri kullanılarak değerlendirilmiştir. Ekstrelerin total fenol ve flavonoit içerikleri Folin- Coicalteu ve aluminyum klorür kolorimetrik yöntemleri kullanılarak sırasıyla 63.45±0.25-68.92±0.42 mg/g kafeik asit ve 4±1 - 210±9 mg/g kersetin olarak belirlenmiştir. Ayrıca T. longirostris var. longirostris ve T. pratensis subsp. orientalis ekstrelerinin fenolik asit; klorojenik asit, kafeik asit, ferulik asit, rosmarinik asit, p-kumarik asit ve flavonoit; apigenol, luteolol, kersetol, hiperozit, rutin, hesperidin içerikleri kalitatif ve kantitatif olarak ters faz yüksek basınçlı sıvı kromatografisi kullanılarak tespit edilmiştir. Klorojenik asit araştırılan tüm türlerde tespit edilmiştir. En yüksek klorojenik asit miktarı T. longirostris var. longirostris toprak üstü kısımlarında 578.22 ± 4.19 µg/mg olarak tespit edilmiştir.
