Daftar Isi:
- Isolation and characterization of triterpenoidscompounds have been donesuccesfully to hexane extract of bark cherry plant (Muntingia calabura.L). Extraction sample of cherry extract was done by using maceration method. Compuond isolation was done by using column chromatography method with eluent system is SGP (Step Gradient Polarity). Isolated compound obtained in the form of a white crystalline solid needle at melting pointis 131-132oC and became maroon after reagent is added LB (Liebermann Burchard). At Ultraviolet spectroscopy showed a maximum wavelength absorption at 202 nm. FT-IR spectroscopy showed bending CH2 and bending CH3 at a wavelength of 1465.62 and 1382.36 cm-1 and other groups such O-H stretching, C-O stretching, C-H alkane and C=C stretching isolated.
