Tóm tắt
Nghiên cứu này đánh giá hàm lượng fucoidan, polysaccharide và polyphenol trong năm loài rong nâu thu thập tại huyện đảo Lý Sơn, nhằm xác định tiềm năng khai thác và nuôi trồng bền vững. Kết quả phân tích cho thấy, Sargassum sp. có hàm lượng fucoidan cao nhất (5,66 ± 1,60%), trong khi Turbinaria ornata có hàm lượng polyphenol cao nhất (431,81 ± 115,46 mgGAE/100g rong khô). Hàm lượng polysaccharide chênh lệch không đáng kể giữa các loài, trong đó, T. ornata đạt giá trị cao nhất (26,57 ± 8,37%). Sự khác biệt về hàm lượng các hợp chất sinh học có thể do yếu tố di truyền, môi trường sống và giai đoạn phát triển của rong. Những kết quả này góp phần cung cấp cơ sở khoa học cho việc khai thác hợp lý và phát triển nguồn lợi rong biển, hướng tới sử dụng bền vững trong công nghiệp thực phẩm, dược phẩm và bảo tồn hệ sinh thái ven biển.
