Abstract

Isolation and Analysis of Genistein of Overripe Tempe using Column Chromatography MethodABSTRACTGenistein is one of the aglycone isoflavone compounds in tempe that has various biochemical activities, including anticancer, antitumor, and antioxidants. Commonly used isoflavone extraction methods resulted in isoflavone crude extract. The aim of this study was to isolate the genistein of overripe tempe through determining the appropriate combination of mobile phases in genistein isolation and the determination of genistein content in both crude extract and isolate. The overripe tempe was first extracted, then genistein was isolated from the crude extract using column chromatography method. The determination of mobile phase combination was done by Thin Layer Chromatography while the genistein content was quantitatively determined by using High Performance Liquid Chromatography. The results showed that the appropriate combination of mobile phase for genistein isolation was chloroform : methanol (15 : 1, v/v). Genistein content in the crude extract and isolates were 4737.50 and 31.36 μg/g extract, respectively. The genistein purity in the isolates was 63.80%, while the purity in the isoflavone extract was 31.98%.Keywords: genistein, HPLC, isoflavone, overripe tempe, TLC ABSTRAKGenistein merupakan salah satu senyawa isoflavon aglikon dalam tempe yang memiliki bermacam-macam aktivitas biokimia, diantaranya antikanker, antitumor, dan antioksidan. Metode ekstraksi isoflavon yang umum diterapkan, menghasilkan ekstrak kasar isoflavon yang masih berupa campuran. Tujuan dari penelitian ini adalah untuk mengisolasi genistein dari tempe busuk melalui tahap penentuan kombinasi fase gerak yang tepat dalam isolasi genistein serta penentuan kandungan genistein baik dalam ekstrak kasar maupun isolat. Tempe busuk mula-mula diekstrak, selanjutnya genistein diisolasi dari ekstrak kasar menggunakan metode kromatografi kolom. Penentuan kombinasi fase gerak dilakukan secara Kromatografi Lapis Tipis, sedangkan kandungan genistein secara kuantitatif ditentukan dengan menggunakan Kromatografi Cair Kinerja Tinggi. Hasil penelitian menunjukkan bahwa kombinasi fase gerak yang tepat untuk isolasi genistein adalah kloroform : metanol (15 : 1, v/v). Kandungan genistein dalam ekstrak kasar dan isolat genistein berturut-turut sebesar 4737,50 dan 31,36 μg/g ekstrak. Kemurnian genistein dalam isolat adalah sebesar 63,80%, sedangkan kemurniannya dalam ekstrak isoflavon adalah sebesar 31,98%. Kata Kunci: genistein, HPLC, isoflavon, tempe busuk, KLT
