The Antioxidant Effectivity of Combination Banana Peel Extract and Orange Peel Extract

Abstract

Oxidation reactions to foods and drugs can be inhibited by using antioxidants that binding to free radicals and reactive molecules. The Ambonese banana (Musa paradisiaca) peel and orange (Citrus reticulata) peel have antioxidant activity potency. The aim of this research is knowing the antioxidant activity of combination Ambonese banana (Musa paradisiaca) peel and orange (Citrus reticulata) peel. IC50 for antioxidant activity potency between Ambonese banana (Musa paradisiaca) peel and orange (Citrus reticulata) peel is expected to increase the antioxidant activity if used a combination that can inhibit oxidation reaction. IC50 indicates the inhibit concentration of antioxidant activity. The compound that has the highest antioxidant activity will show lowest level of IC50. The antioxidant activity test was performed by DPPH method using UV-Vis spectrophotometer on 516 nm and color change of DPPH from purple to yellow when both of them react with an antioxidant compound. The results of IC50 of banana peel extract was 114 mcg / mL; IC50 of orange peel extract was22.2 mcg / mL. The highest inhibition of the combination of both extracts was 73.53% consisting of 25 μL (0,005%) sample of tangerine orange peel extract and 75 μL (0,015%).The biggest inhibition of the combination of both extracts was 73.53% consisting of 25 μL (0.005%) samples of tangerine orange peel extract and 75 μL (0.015%).

Skrining Fitokimia dan Penentuan Kadar Flavonoid Ekstrak Etanol Limbah Kulit Pisang (Musa acuminata Colla)

“…Penelitian menyebutkan adanya beberapa kandungan senyawa metabolit sekunder pada kulit pisang sehingga kulit pisang dapat dimanfaatkan sebagai antioksidan yang akan menghambat terjadinya proses penuaan (Fatemeh et al, 2012;Sula et al, 2018). Adanya komponen aktif dalam kandungan kulit pisang seperti flavonoid dan fenol akan berperan untuk antioksidan (Al Amri & Hossain, 2018;Hama & Umur, 2018;Mirtha Guerrero-Alva, 2019) (Susanti & Anugrah Destyawati, 2019;Ulfa et al, 2020;Wahyuni et al, 2019).…”
