Brassicasterol (24-methyl cholest-5,22-dien-3β-ol) is a 28-carbon sterol synthesised by several unicellular algae (phytoplankton) and some terrestrial plants, e.g., oilseed rape.



  • This compound has frequently been used as a biomarker for the presence of (marine) algal matter in the environment.


  • Brassicasterol in wild coriander leaves
    Eryngium foetidum is a Caribbean plant used in folk medicine for the treatment of several antiinflammatory disorders. The extract is rich in terpenic compounds alpha-cholesterol, brassicasterol, campesterol, stigmasterol (as the main component, 95%) clerosterol, beta-sitosterol, delta 5-avenasterol, delta (5)24-stigmastadienol and delta 7-avenasterol.
  • Brassicasterol in Snails and Slugs
    Snails and slugs belong to the phylum Mollusca. The sterols of slugs include eight different sterols: cholesterol is 76-85% of the total sterols, brassicasterol accounts for 4-13%; other sterols identified are lathosterol, 24-methylene cholesterol, campesterol, stigmasterol, sitosterol and sitostanol. In contrast, snails contain two additional sterols, desmosterol and cholestanol. Of the polyunsaturated fatty acids in slugs, linoleic (18:2n-6) and arachidonic acids (20:4n-6) are the major n-6 fatty acids, while linolenic(18:3n-3) and eicosapentaenoic acids (20:5n-3) are the predominant n-3 fatty acids. Docosahexaenoic acid (22:6n-3), the end product in the n-3 fatty acid synthetic pathway and an important membrane fatty acid of mammals, fish and birds, is absent in both slugs and snails.
  • Brassicasterol in Fungi
    Two groups of fungi isolated from human skin and nail are the dermatophytes Epidermophyton, Microsporum and Trichophyton species and the non-dermatophytes Hendersonula toruloidea and Scytalidium hyalinum. Examination of the sterol composition of these fungi by gas chromatography-mass spectrometry has identified five new sterols from dermatophytes, namely cholesterol, campesterol, episterol, fecosterol and sitosterol. These sterols, with ergosterol and brassicasterol, were also identified from extracts of H. toruloidea and S. hyalinum.
