HÀM LƯỢNG PHENOLIC TỔNG SỐ VÀ TIỀM NĂNG SINH HỌC CỦA CAO CHIẾT METHANOL TỪ ĐỊA Y PYRENULA SP.
Nội dung chính của bài viết
Tóm tắt
Địa y thuộc chi Pyrenula có tính đa dạng cao và phân bố rộng rãi tại Việt Nam, nhưng chúng còn nhận ít được quan tâm trong các nghiên cứu về hóa học và hoạt tính sinh học. Do đó, thành phần hóa học cùng các hoạt tính chống oxi hóa, kháng khuẩn và ức chế enzyme α - glucosidase của địa y Pyrenula sp. thu tại Thành phố Hồ Chí Minh đã được khảo sát. Kết quả sàng lọc hóa học đã xác nhận sự hiện diện của alkaloid, terpenoid, coumarin, quinone, tannin, phenol và flavonoid trong dịch chiết. Hàm lượng phenolic tổng số (TPC) được xác định là 30,26 ± 0,51 mg GAE/g dịch chiết. Về hoạt tính sinh học, dịch chiết thể hiện khả năng chống oxi hóa ở mức trung bình trong thử nghiệm loại gốc tự do DPPH, với giá trị IC50 là 97,4 ± 8,5 μg/mL. Bên cạnh đó, khả năng ức chế α - glucosidase của cao chiết (IC50 = 46,5 ± 3,6 μg/mL) cho thấy tiềm năng trong việc hỗ trợ điều trị bệnh đái tháo đường. Thêm vào đó, cao chiết cho thấy hoạt tính kháng khuẩn mạnh đối với Staphylococcus aureus, được xác nhận qua đường kính kháng khuẩn đạt 20,9 ± 0,1 mm và giá trị MIC là 15,62 μg/mL. Những kết quả này cho thấy triển vọng của địa y Pyrenula như một nguồn dược liệu tự nhiên có hoạt tính sinh học phục vụ cho các mục đích điều trị bệnh.
