This study addresses this gap by examining the inhibition efficacy of sumac powder and seeds for mild steel in 1M HCl, where biomass forms are compared directly in their native states. To elucidate the underlying mechanism, a comprehensive characterization was conducted using extracts obtained with water, ethanol, acetone, and chloroform to identify the influence of solvent polarity on the biomass matrix. Physicochemical analyses revealed that the seed form, particularly in ethanolic profiles, exhibits a higher total phenolic content (267.4 mg GAE/100 g) and superior redox-active profiles. Electrochemical evaluations via potentiodynamic polarization and EIS demonstrated that inhibition efficiency reaches a maximum of 60.79% for the seed form at 200 ppm. This performance is established as a direct consequence of the seed matrix’s higher antioxidant capacity and stabilized profile, which facilitate a more resilient adsorptive film than the powder form. This study proves that sumac seeds, as a byproduct, offer a robust protective layer through synergistic phytochemical interactions.</p></abstract>

                            <p>Sumak (Rhus coriaria L.)’nin antioksidan özellikleri yaygın olarak belgelenmiş olsa da toz ve çekirdek formları arasındaki doğrudan bir karşılaştırma yoluyla yeşil korozyon inhibitörü olarak sistematik değerlendirmesi daha önce araştırılmamıştır. Bu çalışma, sumak tozu ve çekirdeklerinin 1M HCl ortamındaki korozyon inhibisyon etkinliğini, biyokütle formlarının doğrudan kıyaslandığı özgün bir kurguyla incelemektedir. Çözücü polaritesinin (su, etanol, aseton ve kloroform) biyokütle matrisi üzerindeki etkisini belirlemek ve mekanizmayı aydınlatmak amacıyla kapsamlı bir karakterizasyon yürütülmüştür. Fizikokimyasal analizler, çekirdek formunun toz formuna kıyasla daha yüksek toplam fenolik içeriği (26.4 mg GAE/100 g) ve üstün redoks-aktif profil sergilediğini göstermiştir. Elektrokimyasal değerlendirmeler, inhibisyon veriminin 200 ppm’de çekirdek formu için %60.79’a ulaştığını kanıtlamıştır. Elde edilen bu performansın, çekirdek formunun toz formuna kıyasla sahip olduğu üstün antioksidan kapasitesinin ve stabilize profilinin doğrudan bir sonucu olduğu ve metal yüzeyinde daha dirençli bir adsorpsiyon filmi oluşturduğu saptanmıştır. Bu çalışma, sumak çekirdeklerinin bir yan ürün olarak, sinerjik fitokimyasal etkileşimler yoluyla sağlam bir koruyucu şelat tabakası sağladığını kanıtlamaktadır.</p></trans-abstract>
