From the cyclohexane extract of the leaves of Murraya exotica, five novel phytosterols: (23 S)-23-ethyl-24 methyl-cycloart-24(24')-en-3j-01; 3~-methoxy-(23S)-23-ethyl-24-methyl-cycloart-24(24')-en-3~-ol; (23 S)-23-ethyl-- 24-methyl-cycloart-24(24')-3/?-yl acetate; (23 &23-isopropyl-24-methyl-cycloart-25-en-3/&ol and (23 [)-23-isopropyl-24-methyl-cycloart-25-en-3/I-yl acetate have been isolated. Structural elucidation of the isolated compounds is based on physical, chemical and spectral analysis including IR, 'H and 13C NMR and mass spectrometry.
