Abstract

This study investigates the phytochemical composition and bioactive properties of Silybum marianum L. seeds collected from Iraq and Türkiye, two regions with a history of traditional medicinal use of this herb. Extracts were analyzed for total phenolic and flavonoid content (TPC and TFC) using colorimetric methods, and for antioxidant [2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays] and tyrosinase inhibitory activity. Results showed that Turkish extracts had significantly higher TPC and TFC (165.65 ± 6.99 mg GAE/g and 7.66 ± 0.71mg QE/g, respectively) compared to Iraqi extracts, which correlated with enhanced antioxidant and tyrosinase inhibition. The study underscores the impact of regional and environmental factors on the medicinal attributes of S. marianum L., offering valuable information for optimizing its application in the pharmaceutical and cosmetic industries. Turkey.

Özet

Bu çalışma, bu bitkinin geleneksel tıbbi kullanım geçmişine sahip iki bölge olan Irak ve Türkiye'den toplanan Silybum marianum L. tohumlarının fitokimyasal bileşimini ve biyoaktif özelliklerini araştırmaktadır. Ekstreler, kolorimetrik yöntemler kullanılarak total fenolik ve flavonoit içeriği (TPC ve TFC) ve antioksidan [2,2-difenil-1-pikrilhidrazil (DPPH) ve 2,2'-azino-bis(3-etilbenzotiyazolin-6-sülfonik asit) (ABTS) deneyleri] ve tirozinaz inhibitör aktivitesi için analiz edilmiştir. Sonuçlar, Türk ekstraktlarının Irak ekstraktlarına kıyasla önemli ölçüde daha yüksek TPC ve TFC'ye (sırasıyla 165.65 ± 6.99 mg GAE/g ve 7.66 ± 0.71mg QE/g) sahip olduğunu ve bunun da gelişmiş antioksidan ve tirozinaz inhibisyonu ile ilişkili olduğunu göstermiştir. Çalışma, bölgesel ve çevresel faktörlerin S. marianum L.'nin tıbbi özellikleri üzerindeki etkisinin altını çizmekte ve ilaç ve kozmetik endüstrilerindeki uygulamalarını optimize etmek için değerli bilgiler sunmaktadır.
