ABSTRACT

Dessert banana that have AA, AAA, and AAB genotypes is one of the groups from the great diversity of bananas. Their nutritional content and antioxidant compounds can be accessed better than cooking banana by the human body. This research aimed to investigate antioxidant potential of the ripe pulp from ten Indonesian dessert banana cultivars. They were Ambon Putih, Ambon Kuning, Ambon Badak, Ambon Lumut, Raja Sereh, Raja Bulu, Lampung, Papan, Rejang, and Udang. Total polyphenol content, total flavonoid content, and IC₅₀ value were respectively determinated using Folin Ciocalteu method, AlCl₃ methode, and DPPH method. In addition water content and extract yield percentage also were analyzed. The freeze dried banana pulp was macerated using 96% ethanol for 24 hours then filtered and evaporated using a rotary evaporator. The highest water content and yield percentage were shown respectively by Ambon Badak (AAA) at 73.84% and Papan (AAA) at 68.95% extract rendemen. The highest total polyphenol and flavonoid content ware shown respectively by Rejang (AA) at 3498.63 mg GAE/Kg extract and Ambon Lumut (AAA) at 2756.07 mg QE/Kg extract. IC₅₀ values of banana pulp ranged from 3047.42 mg/L on Rejang (AA) cultivar to 14282.84 mg/L on the Papan cultivar. Rejang is the recommended cultivar for the highest total polyphenol while Ambon Lumut is recommended for the highest flavonoid content. These cultivars are recommended bananas for consumption or for further development.
