The chemical composition of Garcinia kola Heckel (Clusiaceae) mesocarp was determined.The results of proximate analysis have showed that the mesocarp of Garcinia kola Heckel contained seven (7) chemical families: flavonoids, tannins, alkaloids, anthraquinons, saponosids, terpenoïds, steroids and reducing compounds. The average value of total phenols, flavonoids, anthocyans in the mesocarp at the last stage of maturity was: 68.33 ± 0.85 ;14.67±1.04; 2.92 ± 0.34 mg/l, respectively. The average percent in water content, crude proteins, carbohydrates and total lipids was: 84.40 ± 1.27; 5.20±0.03; 27.77± 0.59; and 18.70 ± 0.85 %, respectively. The mean value of ascorbic acid and total acidity was 29.26 ± 0.99 mg and 64.48± 1.89 méq.g HSO /l. The physical and mineral element composition were: pH 2.91 ± 0.02; E.C 1855.33 ± 55.41µS/cm, T.D.S 1006.33 ± 5.86 mg/l and Ca 4.30 ± 0.14; Mg 2.40 ± 0.14; Na 0.26 ± 0.09; K 31.04 ± 1.53; P 59.32 ± 1.83; Fe 126.53 ± 15.05; N 19.54 ± 0.17; Zn 8.79 ± 0.30; Cu 0.93 ± 0.05; Mn 4.38 ±0.17 mg/100g. The ash content was 7.970±0.099 % (450°C), respectively.
