F) FRILIA ELFANI PUTRI Department of Chemistry, Faculty of Mathematics and Natural Sciences Sebelas Maret University ABSTRACT Calophyllum soulattri which is known as 'slatri' in central java usually used as skin diseases traditional medicine. Soulattri contains compounds terpenoid, steroid, coumarin, chromanon and xanthone. Steroid compounds have some biological activity like antiinflamatory, antibactery and antifungal.

In this research, isolation of steroids constituent from C. Soulattri leaves was conducted by maceration method using ethyl acetate as solvent. The separation and purification process has been done by vacuum liquid chromatography and flash chromatography. The structure then analyzed by spectroscopy UV, FTIR, and NMR (1H NMR, 13C NMR, HSQC and HMBC). The UV spectrum showed a peak at 位 max 237 nm that indicate as a chromophore group from an enon. The FTIR spectra showed the presence of functional groups C=O carbonyl at 1677 cm-1 and C=C alkene at 1618 cm-1.
The 13C NMR spectra showed six alkenes carbons and fifty two alkanes carbon. The 1H NMR spectra showed alkanes protons and alkenes protons. Based on the analysis result, the compounds are suggested as a mixture of two compounds (4-stigmastene-3-one and 4.22-stigmastadiene-3-on).
