has　been　established　by　a　few　workers,　but　so　far　as　we　know　in　the　case　of　the
derivatives　of　sphingolipid,　no　such　substance　has　previously　been　reported.  The　present　authors　prepared　a　large　amount　of  sphingolipid　fractions　from　the  fresh-water　bivalve,　Corbicula　sandai,　and　separated　them　by　Florisil　column　chromatography,　followed　by　preparative　thin　layer　chromatography.　We　succeeded　in  obtaining　a　notable　phospholipid　which　was　negative　with　ninhydrin　reagent,　and  gave　a　faster-moving　spot　on　thin　layer　chromatography.　The　lipid　was　practically
free　from　sugar　and　glycerol,　and　on　hydrolysis　liberated　only　aminoethylphosphonic
acid　as　phosphorus　component.　And　quantitative　analyses　of　P,　N,　fatty　acid　and   sphingosine　base　showed　to　be　in　a　ratio　of　1:2:2:1.   From　these　results　the　lipid　was　proved　to　be　ceramide N-(acyl)aminoethylphosphonate (N-acyl CAEP).　The  component　fatty　acids　of　N-acyl CAEP　consisted　mainly　of  palmitic　and　stearic　acids,　but　no　unsaturated　ones　could　be　detected.
On　the　other　hand　the　partial　synthesis　of　N-palmitoyl　CAEP　was　studied　by　using  CAEP　from　the　bivalve　as　a　starting　material　and　comparative　examinations　were  made　concerning　chemical　nature　of　the　synthetic  N-acyl　derivatives　with　that　of  the　isolated　one.　Similar　results　were　obtained　from　infrared　spectra,　mobilities　on  thin　layer　chromatography　and　resistance　against　phospholipase　C., 滋賀大学教育学部紀要, 自然科学, 第21号, pp.24-30},
