Abstract
Areca catechu (Areca catechu. L) contains many chemical components, namely, pectin, cellulose, hemicellulose, lignin, pectin oxalate and flavonoids. Tannins are very complex organic substances and consist of phenolic compounds. Tannins are obtained by extraction with water and ethanol solvents because tannins can dissolve with these solvents. This study aims to identify tannin compounds in areca nut using ethanol as a solvent. This research is a laboratory experiment with an extraction process using the maceration method. The areca nut is dried and mashed and then sifted. Then the powder was macerated with 70% ethanol solvent for ± 24 hours, then evaporated and then tested qualitatively and determined the type of tannins. The results showed that areca nut extract was positive for tannins and the type of tannin was condensed tannins.

Summary
Bahan Sabut buah pinang, kertas saring whatman no. 42 aquades, etanol 70%, NaCl 10%, FeCl3, dan gelatin. Bahan Sabut buah pinang, kertas saring whatman no. Setelah sabut buah pinang kering, selanjutnya dihaluskan dengan blender dan diayak menggunakan pengayak ukuran 30 mesh agar terbentuk serbuk yang lebih halus dan seragam Pembuatan Ekstrak Etanol 70% sabut buah pinang. Sebanyak 100 gram serbuk sabut buah pinang direndam dengan pelarut etanol 70% selama ± 24 jam dan selanjutnya disaring menggunakan kertas saring whatman. Kemudian dilanjutkan dengan penguapan pelarut etanol 70% menggunakan Rotary Evaporator hingga diperoleh ekstrak kental, untuk selanjutnya disebut dengan ekstrak sabut buah pinang 70%. Hasil ekstrak etanol 70% sabut buah pinang yang didapatkan, maka selanjutnya dilakukan uji sebagai berikut, sebanyak 5 ml ekstrak dipipet, lalu dimasukkan ke dalam tabung reaksi.
