Amino acid composition of two spondias gums and its elution profiles

Abstract:

The elution profiles and amino acid composition of two gums from Spondias species (Anacardiaceae) have been determined. Size exclusion chromatography, monitored by the measurement of total carbohydrate and protein showed diferent fractions in the gums from S. purpurea and S. mombin. There are some evidences which may indicate the presence of arabinogalactan (AG) and arabinogalactan-protein (AGP) in those gums. Amino acid composition of both gums showed that hydroxyproline, aspartic acid, glutamic acid, serine, proline, threonine and alanine are present. Hydroxyproline is the main amino acid, of both gums as has commonly been associated with Acacia gums and other genera of Leguminosae.
