Chloroform-methanol extracted lipids of guava seeds amounted to 9.1% on a dry weight basis. Physical and chemical properties of the extracted oil are presented. Gas liquid chromatographic analysis of the methyl esters of the fatty acids of such oil revealed the presence of twelve fatty acids. The fatty acid pattern obtained was generally similar to that of cotton-seed oil. The unsaponifiable matter of such oil was also analyzed by GLC which showed the presence of eight fractions. The protein content in guava seeds was found as 9.73% on a dry weight basis. Qualitative and quantitative analyses of such protein, using amino acid analyzer, revealed the presence of fifteen amino acids.
