| Abstract: | C27, C28 and C29 sterols have been isolated from a Leptosphaeria typhae culture grown in vitro in light on a synthetic medium. These products were characterized by GLC and MS. Saturated and mono-, di- and tri-unsaturated sterols are present, both free and esterified. There are significant differences between these sterols and those in the same fungus grown on “oat water”. Unexpectedly, cholesterol was detected in the latter case. |
