      Abstract
      Buah merupakan salah satu potensi sumber antioksidan. Penelitian mengenai kapasitas antioksidan dan kandungan total fenol buah dari Indonesia masih sangat terbatas. Tujuan dari penelitian ini adalah untuk menganalisis kapasitas antioksidan dan kandungan total fenol dari berbagai jenis buah yang diperjualbelikan dan dikonsumsi di Indonesia. Tiga puluh jenis buah dipilih secara purposif di pasar Anyar, Bogor. Kapasitas antioksidan buah dianalisis menggunakan metode DPPH dan total fenol dianalisis menggunakan metode Folin-Ciocalteau. Hasil menunjukkan bahwa asam jawa memiliki kapasitas antioksidan tertinggi dengan 76.15±0.09 mg AEAC/100 g. Pisang mas memiliki kapasitas antioksidan terendah dengan 1.29±0.14 mg AEAC/100 g. Buah berwarna tua memiliki rata-rata kapasitas antioksidan lebih tinggi dibandingkan dengan buah berwarna muda. Markisa memiliki kandungan total fenol tertinggi dengan 3.25±1.70 mg TAE/100 g, dan pisang kepok terendah dengan 0.12±0.29 mg TAE/100 g. Penelitian ini juga menunjukkan adanya korelasi positif antara kapasitas antioksidan dan kandungan total fenol (p<0.05; r=0.545
       
      Fruit is one of potential sources of antioxidant. Very limited studies have been done in determining the antioxidant capacity and phenolic content of fruits of Indonesia. The objective of this study was to analyze the antioxidant capacity and phenolic content of various types of fruits is traded and consumed in Indonesia. Thirty kind of fruits were selected purposively in Anyar traditional market of Bogor. The antioxidant capacity of the fruits was evaluated by applying DPPH method and total phenolic content was analized by applying the Folin- Ciocalteau method. The results showed that tamarind has the highest antioxidant capacity of 76.15±0.09 mg AEAC/100 g Mas banana is the lowest antioxidant capacity of 1.29±0.14 mg AEAC/100 g. Dark-colored fruits have a higher antioxidant capacity than the light-colored fruit. Passion fruit has the highest total phenolic content of 3.25±1.70 mg TAE/100 g and kepok banana has the lowest total phenolic content of 0.12±0.29 mg TAE/100 g. This study also showed that the positive correlation between antioxidant capacity and total phenolic content (p<0.05; r=0.545).
