Chemical Contents and Bioactivities of Green Algae Ulva rigida and C.Agardh Red Algae Grateloupia turuturu Yamada Extracts

Objective: Edible seaweeds, valued for their rich content of bioactive compounds, have gained recognition in complementary medicine beyond their traditional role in the food and pharmaceutical sectors.Notable examples include Ulva rigida C.Agardh and Grateloupia turuturu Yamada.These seaweeds offer a promising avenue for exploring their bioactive potential in medical and dietary contexts.Methods: Hexane extracts were prepared to elucidate the fatty acid composition of seaweeds via Gas Chromatography-Mass Spectrometry analyses.Subsequently, investigations were conducted to assess the cytotoxicity on human breast cancer cell lines (MCF-7 and MDA-MB-231), as well as examine the antimicrobial and anti-cholinesterase activities of extracts obtained using hexane, dichloromethane:methanol (CH 2 Cl 2 :MeOH, 1:1), methanol (MeOH), and water solvents. Results:The most abundant substances for the U. rigida and G. turuturu species were hexadecanoic acid, octadecenoic acid, and erucic acid compounds.The CH 2 Cl 2 :MeOH (1:1) extract of G. ÖZAmaç: Zengin biyoaktif bileşik içeriği nedeniyle değer verilen yenilebilir deniz yosunları, gıda ve ilaç sektöründeki geleneksel rollerinin ötesinde tamamlayıcı tıpta da tanınmaktadır.
