The seed cotyledons of Chrysophyllum albidum were analyzed for phytochemical, proximate and heavy metal composition. The phytochemical analysis indicated the presence of saponins, tannins, phenols, flavonoids, terpenoids, and steroids. This showed that C. albidum is a potential source of bioactive molecule which could be used in the treatment of various diseases. Proximate analysis showed that C. albidum seed cotyledon is a relevant source of essential nutrients especially for carbohydrates, proteins, lipids, and fibre. Its low moisture content indicates that it would have a long shelve life. Heavy metal/composition analysis indicated the presence of Lead (Pb) and Cadmium (Cd) which are poisonous heavy metals. The Lead level in the seed cotyledons is 0.0302 mg/dm3 which is significantly lower than 1.00 mg/dm3 threshold concentration, suggesting that the consumption of the cotyledons may be safe. However, Cadmium concentration level was 0.0079 mg/dm3 which is infinitesimally higher than 0.0075 mg/dm3 threshold concentration, suggesting that C. albidum seed cotyledons may be toxic and its ingestion injurious.
