Melinjo(Gnetum gnemon L.) merupakan komoditas pangan yang melimpah di Indonesia&#13;
dan memiliki banyak manfaat bagi pengkonsumsinya. Melinjo merupakan tanaman yang&#13;
mengandung antioksidan tinggi. Penelitian ini bertujuan untuk mendapatkan jenis pelarut (air dan&#13;
etanol 70%) dan metode ekstraksi terbaik (maserasi, soxhletasi dan digesti) dari ekstrak daun&#13;
melinjo berdasarkan kandungan kimia dan aktivitas antioksidannya. Rancangan penelitian&#13;
rancangan acak kelompok (RAK) pola faktorial yang terdiri atas 2 faktor. Faktor pertama adalah&#13;
jenis pelarut (J) terdiri dari dua taraf yaitu J 1 = pelarut air dan J 2 = pelarut etanol 70%. Faktor&#13;
kedua metode ekstraksi (M), yang terdiri atas tiga taraf yaitu M 1 = metode maserasi, M 2 = metode&#13;
soxhletasi, dan M3 = metode digesti. Kombinasi perlakuan dalam penelitian ini adalah 2 × 3 = 6&#13;
(enam) kombinasi perlakuan dan menggunakan 3 (tiga) kali ulangan, sehingga diperoleh 18 satuan&#13;
percobaan. Hasil penelitan menunjukkan bahwa jenis pelarut dan metode ekstraksi berpengaruh&#13;
tidak nyata terhadap rendemen dan total fenol namun jenis pelarut berpengaruh nyata terhadap&#13;
total fenol dan ada interaksi keduanya terhadap aktivitas antioksidan.&#13;

Abstract&#13;
Melinjo (Gnetum gnemon L.) is one of abundant food commodities in Indonesia and it&#13;
gives many benefits to the consumers. Melinjo is a plant that contains high antioxidants. This&#13;
study aims to determine the proper kind of solvent (water and ethanol 70%) and the best extraction&#13;
method (maceration, soxhletation and digestion) of melinjo’s leaves extract based on the chemical&#13;
contents and antioxidant activity. This research design was a randomized block design (RBD)&#13;
factorial consisting of two factors. The first factor was the types of solvents (J) with two levels; J 1&#13;
= water and J 2 = ethanol 70%. The second factor was extraction methods (M) consisting of three&#13;
levels, namely M1 = maceration method, M2 = soxhletation method, and M3 = digestion method.&#13;
The combination treatment in this study was 2 × 3 = 6 (six) with 3 (three) replications, in order to&#13;
obtain 18 experimental units. The results showed that the types of solvents and extraction methods&#13;
did not give a significant effect on yield and total phenols, but the solvent types showed a&#13;
significant effect on total phenol and its interaction with the methods affected to antioxidant&#13;
activity significantly.&#13;
