Kapasitas Antioksidan Buah Salak (Salacca Edulis REINW) Kultivar Pondoh, Nglumut Dan Bali Serta Korelasinya Dengan Kadar Fenolik Total Dan Vitamin C

Indonesia is rich in various superior cultivar of snake fruit such as Pondoh, Nglumut and Bali with increasing in production year by year. However, exploration of Indonesian snake fruit related to snake fruit's potential as natural antioxidant source has not been done much yet. The objectives of this research were (1) to determine the effect of snake fruit cultivar and solvent polarity to the antioxidant capacity (radical DPPH scavenging activity and reducing power) and bioactive compounds content (total phenol and ascorbic acid), (2) investigating the correlation between antioxidant capacity of snake fruit toward its total phenolic and ascorbic acid content. This research used Completely Randomized Design (CRD) with two factors, those are cultivars (Pondoh, Nglumut and Bali) and solvents (ethanol and water). The research showed that Nglumut and Bali cultivars had no differences in DPPH radical scavenging activity, total phenolic and ascorbic acid content, although they were significantly higher than on Pondoh cultivar. The reducing power of Nglumut cultivar was significantly higher than that of in Bali and Pondoh cultivars. Ethanol extract had significantly higher antioxidant capacity, total phenolic and ascorbic acid content than that of water extract. Each snake fruit cultivar had significantly strong correlation value between antioxidant capacity and its total phenolic content (r = 0.83 – 0.97, p<0.01) and its ascorbic acid content ( r = 0.77 – 0.95, p
