摘要 Objective:To evaluate the amino acid profile and quality indices of Clerodendrum volubile(C.volubile)leaves.Methods:Dried leaves of C.volubile were blended,defatted and subjected to amino acid analysis using the technicon sequential multi-sample amino acid analyzer.The amino acid quality indices which covers for chemical score,essential amino acid index,nutritional index,true digestibility,protein digestibility corrected amino acid score,and digestible indispensable amino acid score were evaluated using standard formulas.Results:Amino acid analysis revealed glutamic acid to have the highest concentration,with cysteine having the least.Aspartic acid had the highest chemical score,this was followed by glycine,histidine and arginine,respectively.The least scores were observed in serine and methionine.Glutamic acid had the highest value for true digestibility and protein digestibility corrected amino acid score,with the least observed in cysteine.Digestible indispensable amino acid score evaluation showed histidine to have the highest value for infants(birth to 6 months),threonine for children(6 months to 3 years),while isoleucine was observed to have the highest value for older children,adolescents and adults.The essential amino acid index value was less than 4,while nutritional index value was less than 0.5.Conclusions:These results indicated the leaves of C.volubile as a potential source of amino acids in the human diet as portrayed by its amino acids profile and qualities.
