✦ Synopsis

lhare cerebroside was isolated from hay and concentrate (extracted oilseed used for cattle feed), and the composition of the long-chain bases determined. The principal base was the cis isomer of 4-hydroxy-8-sphingenine (t 18:18c) which has not been reported before. The other trihydroxy bases were t 18 : 18t and t 18 : 0.

Allylic and non-allylic dihydroxy bases were found in concentrate cerebroside and identified as dl 8 : 14, dl 8 : 24, x, dl 8:0 and dl 8 : I x (x = 8?). Cis and trans isomers of mid-chain double bonds (position x) were tentatively identified, and the dihydroxy bases are probably identical to those recently found in wheat flour cerebroside [2J.
