โฆ Synopsis
From freshly fertilimi eggs of the sea hare Aplpiu kitrodni. col-Icctod in Fukuoka Prefecture. the new laxativc lipid, thc diacylglyceryl cther mixturc ( I ) and cholcstcryl estcr mixture (2). in addition to thc thrcc nuclcosidcs 4. 5. and 6. havc becn isolated. Thc structurcs of I and 2 werc elucidated on the basis of chcmical and spectral cuidcncc. The nuclcosidcs 4, 5. and 6 have been identified as 1-(2-deoxy-[3-n-ribofuranosyI)thymine. adenosine, and inosinc, respectivcly.
