Hibiscus ficulneus Linn. (Malvaceae) were 30.8, 8.8 and 14.4, and 19.0, 11.7 and 20.0, respectively. The major fatty acid was 18:1 in C. gigantea and 18:2 in the other two seeds oils. Malvalic, sterculic and dihydrosterculic acids were present in small quantities in A. ficulneus seed oil. The major essential amino acids in the seed proteins were phenylalanine, lysine and histidine in C. gigantea, threonine and arginine in A. caesia and lysine and phenylalanine in A. ficulneus. © 1983 American Oil Chemists' Society.
