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 (2S,3R,4E,8E,10E)‐1‐(β‐d‐glucopyranosyloxy)‐3‐hydroxy‐2‐[(R)‐2‐hydroxy‐15‐tetracosenoyl] amino‐4,8,10‐octadecatriene (4) and (2S,3R,4E,15Z)‐1‐(β‐d‐glucopyranosyloxy)‐3‐hydroxy‐2‐[(R)‐2‐hydroxyhexadecanoyl] amino‐4,15‐docosadiene (7) by means of spectroscopic and chemical methods.
