A new propylcholesterol-type steroid, namely (22E,24S)-24-propylcholest-5en-3α-acetate (1), has been isolated from the stembark of Aglaia angustifolia (Miq.). The structure of 1 was determined on the basis of spectroscopic data including 1D- and 2D-NMR as well as high resolution mass spectroscopy analysis. Compound 1 showed weak activity against the MCF-7 breast cancer cell line.
