Abstract

Telah dilakukan isolasi kandungan kimia sapogenin steroid dart bush Salanum torvum S& Isclasi senyawa dilakukan dengan perkolasi menggunakan pelarut metanol. Identifikasi jumlah senyawa dilakukan dengan kromatografi lapis tipis. Pemisahan selaniutnya dengan kromatografi kcdcrn fasa diamnya adalah silika gel S 60 dan etil asetat kemudian metanol sebagai eluen. Kristal hasil dari kromatografi kolom dimurnikan dengan pelarut n-heksan dan kemudian dengan kloroform. Penentuan jenis senyawa dilakukan dengan membandingkan data waktu retensi HPLC senyawa hash isolasi terhadap data waktu retensi HPLC referensi. Waktu retensi senyawa solasodin adalah 47802 menit. Having been isolated chemical compounds of sapogenin steroid produced by fruits of Salanum tarvum The compounds were isolated by percolation method using methanol, then thin layer chromatography (TLC) was used to determine the compounds in sapogenin steroid. Column Chromatography was used as a subsequent method of separation, where as a stationary phase was silica gel G 60 and ethyl acetate - methanol as an eluent (mobile phase). The crystal produced was- purified by n-hexan and followed by chloroform. For determination the type of compound were done by comparing data of HPLC retention times of reference to that isolated product. It was found the retention times of solasodine 47,802 minutes.
