    Abstract
    Telah dilakukan isolasi senyawa flavonoida dari daun tumbuhan Ingul (Toona sureni (Blume) Merr.) dengan metode ekstraksi. Ekstrak daun Ingul dipisahkan dengan menggunakan metode kromatografi kolom. Identifikasi dilakukan dengan spektroskopi Ultraviolet-Visible (UV-Vis), Spektroskopi Inframerah (FT-IR) dan Spektroskopi Resonansi Magnetik Inti proton 1-H-NMR. Hasil analisis spektrum menunjukkan bahwa senyawa hasil isolasi adalah senyawa flavonoida golongan isoflavanon berupa pasta berwarna kuning dengan massa 47mg dengan Rf=0,44.
     
    Isolation of flavonoid from the leaves of ingul (Toona sureni (Blume) Merr.) has been done by using extraction methods. Extract Ingul leaves separated by using Column Cromatography methods. Identification process was analyzed by Spectroscopy Ultraviolet-Visible (UV-Vis), Spectroscopy Infra Red (FT-IR) and Spectroscopy Proton Nuclear Magnetic Resonancy (1H-NMR). The result analysis of spectrum showed that isolation compound a flavonoida group isoflavone, is yellow crystal with a mass = 47mg and Rf=0,44.
