Polytrichum piliferum Hedw. Ekstraktlarının Antioksidan Aktivitesi ve Bazı Kimyasal Bileşimleri

Yeliz Çakır Sahilli,

Mevlüt Alataş

Abstract: Bu çalışmada, briyofitlerin bir türü olan Polytrichum piliferum'un antioksidan, yağ asidi, mineral analizi ve bazı kimyasal özellikleri araştırılmıştır. Araştırma sonucunda, P. piliferum ekstraktının antioksidan özellikleri ve toplam fenolik içeriği açısından orta düzeyde bir etkiye sahip olduğu belirlenmiştir. Yağ asidi kompozisyonları açısından oleik ve palmitik asit yüksek bulunmuştur. Yapılan mineral analizleri sonucunda ise yüksek oranda alüminyum (Al), demir (Fe), kalsiyum (Ca) ve potasyum (K) birik… Show more

This study investigated the phytochemical content and antioxidant activities of four Sphagnum taxa (S. centrale, S. palustre, S. teres and, S. auriculatum) collected from the Black Sea region of Turkey during two different seasons. The phytochemical groups in the methanol extracts of Sphagnum taxa were identified using qualitative screening methods. The total phenol content of these taxa was quantitatively determined using Folin-ciocalteu reagent with gallic acid equivalents as the standard their antioxidant activities were evaluated by 1,2-diphenyl-1-picrylhydrazyl free radical scavenging ability (DPPH), the CUPRAC test, and phosphomolybdenum assay. Qualitative phytochemical screening of the methanol extracts showed that phenols, tannins, and saponins were present in the extracts, whereas alkaloids and flavonoids were absent. The highest DPPH free radical scavenging activity was observed in 100 µgmL-1 S. teres methanol extract (74.47±0.001% in the first season, September 2021 and 75.37±0.002% in the second season, May 2022). The highest total antioxidant capacity was found in 100 µgmL-1 S. palustre extract (81.00±0.027% in the first season and 84.87±0.002% in the second season). The results of our experiment showed that Sphagnum taxa collected in spring had higher antioxidant activity than those collected in autumn.

En eski karasal bitkiler olan briyofitler, biyoaktif bileşikleri ve terapötik potansiyelleri açısından tohumlu bitkilere göre nispeten daha az incelenmişlerdir. Bu çalışmada, akrokarp karayosunlarından Mnium hornum ve Mnium lycopodioides türlerinin biyoaktif bileşikleri (toplam fenolik ve flavonoid içeriği, askorbik asit içeriği, karotenoid içeriği, nitrik oksit süpürme ve deoksiriboz bozunma aktivitesi) ve antioksidan kapasiteleri (ferrik indirgeyici/antioksidan güç deneyi) araştırılmıştır. Araştırma sonucunda, önemli miktarda toplam flavonoid ve fenolik içerdiği belirlenen türler, potansiyel antioksidan ajanlar olarak öngörülmüştür.
