Potensi ulvan dari Ulva lactuca sebagai sumber antioksidan

Abstract

Dinding sel Ulva lactuca menghasilkan ulvan yang merupakan hidrokoloid bersulfat dan berpotensi sebagai antioksidan. Penelitian ini bertujuan untuk menentukan pengaruh lama pemanasan dalam autoklaf (15 dan 20 menit; 121℃) terhadap rendemen, kadar gula dan sulfat, serta aktivitas antioksidan ulvan. Rendemen ulvan, kandungan gula dan sulfat diukur masing-masing dengan metode gravimetri dan spektrofotometri. Ekstrak kering oven diuji gugus fungsi dan antioksidannya menggunakan FTIR dan metode DPPH. Ulvan hanya bisa dihasilkan melalui ekstraksi pada suhu 121℃ waktu 15 menit. Ekstrak kering ulvan memberikan rendemen 1,98%, kandungan gula total 46,06±0,16% dan kadar sulfat 21,53±1,16%. Spektrum FTIR menunjukkan adanya bilangan gelombang 850 dan 790 cm-1 yang merupakan ciri ulvan. Uji DPPH menghasilkan IC50 sebesar 469 ppm, yang tergolong sebagai antioksidan lemah.
