Sterol content of the Myxomycetes Physarum polycephalum and P. flavicomum
E Bullock and CJ Dawson
The sterol content of two Myxomycetes, Physarum polycephalum and P.
flavicomum has been examined. The sterols of the two species are apparently
identical, the two major sterols in each being poriferasterol and
22-dihydroporiferasterol. Threee minor sterols are probably
delta5-ergostenol, ergostanol, and poriferastanol. The triterpenoids of the
two species differ in that, though lanosterol was identified in both,
22-dihydrolanosterol was indicated only in P. flavicomum. The occurrence of
lanosterol together with a typical mixture of plant sterols is somewhat
unusual.
