THE ELEMENTAL AND AMINO ACID STATUS OF Persea americana (AVOCADO PEAR) SEED OF TWO COMMUNITIES IN...

To determine the quality of Persea americana (Avocado Pear) seed based on elemental and amino acid content, qualitative and quantitative investigations were undertaken. Samples were taken from polluted and presumably non-polluted sites in Rivers State's Ogoni axis and processed according to established protocols. The elements were determined using an Atomic Absorption Spectrophotometer (AAS), while the amino acids were identified using a derivatization approach followed by High Performance Liquid Chromatography (HPLC) procedures. In the contaminated environment, the findings of detectable concentrations (ppm) of the elements were Mg>P>K>Fe>Zn>Mn>Cu>Ni>Co, while in the non-polluted environment, it was Zn>K>Mg>Ni>Cr>Cu>P>Fe>Mn>Co. Despite the fact that concentrations were often higher in polluted areas than in non-polluted areas, almost all surpassed FAO/WHO limits, with the exception of iron and phosphorus in the non-polluted area. Chromium, on the other hand, was not found in the polluted environment. Apart from asparagine and glutamine, a total of 18 standard amino acids were discovered. A similar trend of greater concentrations in polluted environments compared to non-polluted environments was observed. The non-essential amino acid glutamatic acid had the highest concentration (ppm) in the polluted environment, with a mean value of 11.190 0.011, and tryptophan had the lowest, with a mean value of 1.065 0.004. In the non-polluted environment, aspartic acid had the highest content (5.200 0.002) and the lowest (0.225 0.006) in methionine. Because of likely differences in anthropogenic activity in the area, the concentrations of both amino acids and elements differed significantly (p0.05) between the polluted and unpolluted areas. Despite the fact that environmental conditions may have had a substantial impact on the results, P. americana seeds can be regarded a rich source of plant proteins.
