Abstract :

Terminalia catappa is a common tree found in Guyana but it is much underutilized. The objective was therefore set to investigate phytochemicals, heavy metals and N.P.K analysis. The medicinal and nutritive potential of two common varieties of the plant; the red and yellow varieties. Phytochemical screening was also determined using standard screening methods. The leaves of T. catappa L were found to contain saponins, general glycosides, flavonoids, alkaloids, anthraquinones, anthroquinone, glycosides, terpenoid, steroids and alkaloids present. In addition Qualitative estimation of phytochemicals was performed in different solvent extracts, namely ethyl acetate, ethanol, methanol and aqueous extracts. The results were represented as ‘+’ for the presence and ‘–‘for the absence of phytochemicals. N.P analyses were done by total Kjeldahl digests by UV-VIS spectrophotometry, and K analysis was done in Kjeldal digests by Flame photometry method. Key words: Terminalia catappa, heavy metals, phytochemicals, ethanol, methanol, aqueous extract
