Isolasi klorofil a dan analisis aktivitas antioksidan dari mikroalga C. vulgaris

Abstract

Klorofil adalah pigmen hijau yang ditemukan dalam membran tilakoid yang terdiri atas klorofil a, b, c, d, dan e, yang bermanfaat sebagai antioksidan, antiinflamasi, antimutagenik, dan antikanker. Penggunaan klorofil dari mikroalga belum banyak dieksplorasi dibandingkan dengan klorofil dari tanaman darat. Penelitian ini bertujuan untuk mengisolasi dan menentukan aktivitas antioksidan klorofil a dari mikroalga C.vulgaris. Metode penelitian yang digunakan adalah eksperimen laboratorium, dengan tahapan ekstraksi mikroalga C. vulgaris menggunakan pelarut etanol 96%, fraksinasi crude ekstrak C. vulgaris dengan n-heksana, identifikasi klorofil dan penentuan eluen terbaik untuk isolasi KLT, isolasi fraksi untuk memperoleh pigmen klorofil selanjutnya diuji KLT, kadar total klorofil dan aktivitas antioksidan. Hasil pengujian meliputi uji rendemen, kromatografi lapis tipis (KLT), kadar total klorofil, dan uji aktivitas antioksidan dengan metode DPPH. Hasil penelitian menunjukkan bahwa klorofil a dapat diisolasi melalui ekstraksi menggunakan etanol 96%, fraksinasi dengan n-heksana, dan pemurnian dengan kromatografi kolom menggunakan pelarut petroleum eter (7:3). Nilai IC50 dari klorofil a yang dihasilkan adalah 63,99±5,46 ppm, yang termasuk dalam kategori antioksidan kuat. Temuan ini menunjukkan bahwa klorofil a dari C. vulgaris memiliki potensi sebagai sumber antioksidan alami yang efektif.
