Isolasi dan Identifikasi Saponin dari Ekstrak Leunca (Solanium ningrum L) Secara Spektrofotometri Infra Merah
Penelitian ini dilakukan untuk mengisolasi dan mengidentifikasi senyawa saponin dengan maserasi menggunakan etanol 95% sampai mendapat ekstrak kering sebanyak 20 gram dengan dipanaskan menggunakan evaporator. Ekstraksi kedua dilakukan menggunakan corong pisah dengan pelarut dietil eter dan n-butanol. Identifikasi saponin dilakukan dengan tiga parameter uji diantaranya uji busa, uji warna dan gugus fungsi menggunakan Spektrofotometer Infra Merah. Hasil pengukuran Spektrofotometri Infra Merah menunjukkan Ekstrak Daun Launca mengandung beberapa gugus fungsi sebagai berikut : gugus –OH (puncak yang lebar pada bilangan gelombang 3444,87 cm-1), regang –CH alifatik simetri (bilangan gelombang 2926,01 cm-1 dan2854,65 cm-1, regang C=C tidak terkonjugasi pada bilangan gelombang 1606,7 cm-1, adanya regang C-H (bilangan gelombang 1074,35 cm-1 dan 1045,42 cm-1), dan adanya vibrasi bengkokan simetris C-O pada bilangan gelombang 1386,82 cm-1.Kata kunci: Daun leunca; spektrofotometer infra merah; saponin Isolation and Identification of Saponin from Leunca (Solanium ningrum L) Extract by Infrared SpectrophotometryABSTRACTThis research was conducted to isolate and identify saponin compounds by maceration using 95% ethanol to obtain 20 grams of dry extract by heating using an evaporator.
