Abstract From the water‐insoluble lipid fraction of the chloroform/methanol/water extract of the gonads and body walls of the Patagonian starfish Allostichaster inaequalis , two new glucosylceramides ( 4 and 7 ) were isolated together with the known phalluside‐1 ( 1 ) and two glucosylceramides ( 2 and 3 ) previously isolated from the starfish Cosmasterias lurida . The new compounds were characterized as (2 S ,3 R ,4 E ,8 E ,10 E )‐1‐(β‐ d ‐glucopyranosyloxy)‐3‐hydroxy‐2‐[( R )‐2‐hydroxy‐15‐tetracosenoyl] amino‐4,8,10‐octadecatriene ( 4 ) and (2 S ,3 R ,4 E ,15 Z )‐1‐(β‐ d ‐glucopyranosyloxy)‐3‐hydroxy‐2‐[( R )‐2‐hydroxyhexadecanoyl] amino‐4,15‐docosadiene ( 7 ) by means of spectroscopic and chemical methods.
