Aktivitas inhibisi tirosinase ekstrak etanol rumput laut Ulva lactuca secara in vitro

Abstract

Ulva lactuca kaya senyawa bioaktif yang bermanfaat bagi manusia dan organisme lainnya. Tujuan penelitian ini adalah untuk menentukan aktivitas inhibisi tirosinase pada ekstrak etanol rumput laut U. lactuca secara in vitro. Penelitian ini dilakukan secara bertahap, yaitu proses maserasi U. lactuca dengan pelarut etanol. Ekstrak difraksinasi cair-cair dengan pelarut n-heksana, kloroform, dan air. Ekstrak etanol dan fraksi diuji total fenol, total flavonoid, dan aktivitas inhibisi tirosinase. Nilai total fenol dan flavonoid tertinggi didapatkan dari fraksi n-heksana dengan nilai 9,43±0,27 mgGAE/g dan 9,20±0,49 mgQE/g. Aktivitas inhibisi tirosinase tertinggi diperoleh dari fraksi n-heksan dengan nilai IC50 127,74±6,47 µg/mL. Senyawa aktif yang berperan penting dalam aktivitas inhibisi tirosinase pada ekstrak etanol dan fraksi n-heksana meliputi kalkon, asam ferulat, asam 4-nitrocinamat, asam 4-aminobenzoat, derivat 2TMS, asam 4-hidroksibenzoat, 4-tert-butylfenol, 1-tetradekanol, ester metil asam n-heksadekanoat, asam palmitat, 2-(2-Aminofenil)-1H-benzimidazol, dan asam 5-metilsalisilat. Fraksi n-heksana U. lactuca dapat digunakan sebagai inhibitor tirosinase alami.
