Polar constituents of the green alga Cladophora densa HARVEY, which grows in the tidal zone of the Seto Inland Sea, were identified by GC, HPLC, IR, 1H NMR, MS, synthesis, and chemical transformations to known compounds.
The methanol extract of the dried algae, from which nonpolar constituents were removed beforehand by n-hexane extraction, consisted of large amouts of monoglycerides with C16-and C18-unsaturated fatty acids and L-alanine, and small amounts of glycerol, L-phenylalanine, Ltyrosine, 2, 3, 5, 6-tetraiodo-DL-tyrosine, and galactoside of β-sitosterol.
