Proximate and Vitamin Content of Four Nigerian Pterocarpus Species
Abstract
Determination of the proximate and vitamin contents of four Nigerian Pterocarpus species; Pterocarpus osun, P. soyauxii, P. santalinoides and P. mildbraedii was carried out. Freshly expanded and mature leaves of the plants were used for the analysis. The investigation revealed that
on the average the plants contained carbohydrate (40.36- 63.46%), crude protein (14.88 – 25.38%), crude fibre (8.28 -8.88%), ether extract (5.06-12.52%), ash (4.48 – 8.88%), dry matter (86.56 – 97.52%), moisture content (2.48 – 13.44%) and food energy value (351.12-
395.60mg/cal). The plants composed of 10.20 – 11.80mg/100g retinol, 16.60-18.40mg/100g ascorbic acid, 0.130–0.180mg/100g thiamine and 3.30–3.93mg/100g niacin. The study indicates that the leaves of the
Pterocarpus species have high nutritive contents.
