✦ Synopsis

1-6, AC-1-xadecane-1,3,4-triol (AC-1-10) and (2S,2ЈR,3S,4R,)-2(2-hydroxytetracosanoylamino)hexadecane-1,3,4-triol (AC-1-11). 10 and AC-1-11, were isolated from the ceramide molecular species AC-1, obtained from the less polar fraction of the Positive ion FABMS/MS of each ceramide gave important information for their structure elucidation. Mass spectrometry CHCl 3 /MeOH extract of the starfish Acanthaster planci. The structures of these ceramides were determined on the basis of the dimethyl disulfide derivatives of ceramide was also useful for the determination of the double bond position in of chemical and spectroscopic evidence as (2S,2ЈR,3S,4R,9Z)-2-(2-hydroxyhexadecanoylamino)-9-docosene-1,3,4-triol the long-chain base. (AC-1-6), (2S,2ЈR,3S,4R,)-2-(2-hydroxytricosanoylamino)he-
