Composition of Carapa procera Gum

Abstract

Carapa procera D.C. (family Meliaceae) occurs widely in the forests of the Western Area of Sierra Leone. Between December and February the stem exudes gum varying from pale-green to dark brown. On analysis, a single unpurified nodule gave ash, 1.68 per cent; nitrogen, 0.44 per cent; acetyl groups, 1.84 per cent; alkoxyl groups (calculated as ethoxyl), 2.63 per cent. Results for two other nodules were not significantly different from these. The crude gum dissolves partially in cold water to give a markedly acidic solution.
