Abstract
Gold snail is called “Kowoe” in Celebes Island. They are widely utilized by people as food. This snail also has many properties and benefits. The aims of this study were to determine the best solvent to extract the bioactive components of snails and measure the antioxidant activity. The proximate analysis was caried out, then quantitative test of antioxidant activity by DPPH method was measured. The results of morphometric measurements showed the meat yield 11.86%. The proximate analysis of fresh meat consisted of water content 65.79%, 18.14% protein, 10.49% ash, 4.14% carbohydrates, and fats 3.44%, while the moisture content of dried meat contained 40/ 04%, 38.06% protein, carbohydrates 10.66%, ash 8.53% and 2.70% fat, respectively. The yield of extraction of the active compound using chloroform (non-polar) was 1.78%, ethyl acetate (semi-polar) was 3.41% and 6.63% methanol (polar). The snails kowoe contain more the polar of active compounds. The antioxidant activity of crude extract in methanol solvent (polar) had IC50 values 111.28 ppm (moderate).<br /><br />
Highlights
Keong kowoe merupakan salah satu spesies dari kelas gastropoda dan tergolong dalam keong mas, termasuk kelompok molusca dari famili Ampullariida yang banyak dijumpai disungai, danau, rawa dan persawahan di Kabupaten Konawe, Sulawesi Tenggara
They are widely utilized by people as food
determine the best solvent to extract the bioactive components of snails
Summary
Abstrak Keong mas atau dalam bahasa daerah Sulawesi (Kabupaten Konawe) disebut sebagai “Keong kowoe” banyak dimanfaatkan masyarakat sebagai makanan. Keong ini dipercaya memiliki banyak khasiat dan manfaat, antara lain kandungan antioksidan yang tinggi. Penelitian ini bertujuan menentukan pelarut yang terbaik untuk mengekstrak komponen bioaktif keong mas dan menentukan kandungan antioksidannya. Penelitian ini meliputi analisis proksimat, uji kuantitatif aktivitas antioksidan dengan metode DPPH. Hasil pengukuran morfometrik menunjukkan rendemen daging sebesar 11,86%. Hasil pengamatan didapatkan rendemen hasil ekstraksi senyawa aktif menggunakan pelarut kloroform (non polar) sebesar 1,78%, etil asetat (semi polar) 3,41% dan metanol 6,63% (polar). Rendemen yang tinggi pada pelarut metanol diduga karena keong kowoe mengandung lebih banyak senyawa aktif yang bersifat polar. Hasil uji aktivitas antioksidan ekstrak kasar jenis pelarut metanol (polar) mempumyai nilai IC50 yaitu 111,28 ppm, sehingga tergolong sedang
