Abstract

Bryophytes constitute an important group of plants whose biological activities have not been sufficiently studied. The numerous bioactive compounds in their structures make them significant. In this study the in vitro antioxidant, antidiabetic, and antimicrobial activities of acetone and methanol extracts of Pohlia wahlenbergii moss were evaluated. In determining antioxidant activity, the inhibitory powers of these extracts against two different radicals, DPPH. and ABTS.+ were measured. The results were compared with standard ascorbic acid results. In addition, the α-amylase enzyme inhibition of these extracts was measured to determine their antidiabetic activity. The drug acarbose was used to compare the results. The highest DPPH. and ABTS.⁺ radical scavenging was observed in the acetone extract, with IC₅₀ values of 1.509 and 1.301 mg/mL, respectively. The ABTS.+ radical removal activity was found to be stronger. Antidiabetic activity was determined by α-amylase enzyme inhibition, which was found to be highest in the methanol extract (1.792 mg/mL). The extracts were determined to possess antioxidant and antidiabetic activities. In addition, the in vitro antimicrobial potential of extracts from Pohlia wahlenbergii against various pathogenic microorganisms has been evaluated. Results showed strong antifungal activity, with the acetone extract outperforming the standard drug Fluconazole, exhibiting a 25 mm inhibition zone against Candida albicans and an MIC of 16 µg/mL. The methanol extract also demonstrated broad-spectrum antibacterial effects, notably a 20 mm inhibition zone against Bacillus cereus and Salmonella typhimurium. The selective antimicrobial properties of Pohlia wahlenbergii indicate its potential as a source for developing new natural antibiotics and antifungal agents.

Özet

Briyofitler, biyolojik aktiviteleri yeterince incelenmemiş önemli bir bitki grubunu oluşturmaktadır. Yapılarındaki çok sayıda biyoaktif bileşik, onları önemli kılmaktadır. Bu çalışmada, Pohlia wahlenbergii karayosununun aseton ve metanol özütlerinin in vitro antioksidan, antidiyabetik ve antimikrobiyal aktiviteleri değerlendirilmiştir. Antioksidan aktivitenin belirlenmesinde, bu özütlerin iki farklı radikale, DPPH. ve ABTS.+'ya karşı inhibitör güçleri ölçülmüştür. Sonuçlar, standart askorbik asit sonuçlarıyla karşılaştırıldı. Ayrıca bu ekstraktların antidiyabetik aktivitesini belirlemek için, α-amilaz enzim inhibisyonu ölçüldü. Sonuçları karşılaştırmak için akarboz ilacı kullanıldı. En yüksek DPPH. ve ABTS.+ radikal temizleme aktivitesi sırasıyla 1.509 ve 1.301 mg/mL IC₅₀ değerleriyle aseton ekstraktında gözlendi. ABTS.⁺ radikal temizleme aktivitesinin daha güçlü olduğu bulundu. Antidiyabetik aktivitenin belirlenmesinde, α-amilaz enzim inhibisyonu kullanıldı ve metanol ekstraktında en yüksek seviyede olduğu görüldü (1.792 mg/mL). Ekstraktların antioksidan ve antidiyabetik aktivitelere sahip olduğu belirlendi. Ayrıca, Pohlia wahlenbergii'den elde edilen özütlerin çeşitli patojen mikroorganizmalara karşı in vitro antimikrobiyal potansiyeli değerlendirilmiştir. Sonuçlar, güçlü antifungal aktivite göstermiştir; aseton özütü, standart ilaç Flukonazol'den daha iyi performans göstererek Candida albicans'a karşı 25 mm'lik bir inhibisyon bölgesi ve 16 µg/mL'lik bir MIC sergilemiştir. Metanol özütü de geniş spektrumlu antibakteriyel etkiler göstermiş, özellikle Bacillus cereus ve Salmonella typhimurium'a karşı 20 mm'lik bir inhibisyon bölgesi göstermiştir. Pohlia wahlenbergii'nin seçici antimikrobiyal özellikleri, yeni doğal antibiyotikler ve antifungal ajanlar geliştirmek için potansiyel bir kaynak olduğunu göstermektedir.
