Analytical data are presented for the polysaccharide and proteinaceous components of the gum from the seed of Leucaena glabrata , and gum exudate from Spondia purpurea. The yield on hydrolysis of the polysaccharide was β‐galactose, 25% and 61%, L‐arabinose, 60% and 17%, and D‐galacturonic acid, 12 and 22%, respectively. The methoxy and nitrogen values for S purpurea are in the intermediate range, and for L glabrata they are in the low range. Both gums contain a low proportion of hydroxyproline. Aspartic acid and valine are the major aminoacid constituents present in S purpurea and glycine and aspartic acid for L glabrata. The gums have good solubility in water.
