✦ Synopsis

Fruit and vegetable used in this study were: mango (Mangifera indica), guava (Psidium guajava), pomegranate (PuniCa granatum), fig (Ficus carica), banana (Musa pradisiaca sapientum), colcasia (Colocasia antiquorum), zucchini (Cucurbita pepo) and spinach (spinacia oleracea). Ten samples of each product were collected at the normal stage of maturity and were mixed thoroughly in a waring blender to obtain a homogenous sample. Free amino acids and organic acids were extracted by the methods described by Drawert et al. (1) and List et al. (2). The free amino acids and organic acids fractions were separated using a column of Dawex 50. The high-pressure -liquid-chromatography method of List et al.

(2) was used to identify and quantitate the organic acids (Table 1). The free amino acids were determined by the automated amino acid analyzer Biotronik
