Phytochemical Screening of Methanolic Extracts of Croton Mubango Müll Arg. and Indigofera Hendecaphlla Jacq. from the Province of Huambo, Angola

Abstract

Plant species Croton mubango Müll Agr. and Indigofera hendecaphlla Jacq. they are traditionally used in various diseases in animals and humans in the province of Huambo, Angola. The objective of the present work was to determine the phytochemical composition of methanolic extracts of leaves of said species. The samples to be studied were collected in several places of Comuna Comandante Nzaji in the municipality of Huambo, in the rainy period. They were dried, milled and transferred to the National Center for Agricultural Health (Cuba) for phytochemical screening. The main groups found were primary and secondary aminos, free phenols, tannins, triterpenes and / or steroids and alkaloids. The primary and secondary amino compounds, free phenols, tannins and alkaloids were found in high amounts in the leaves of I. hendecaphlla and for C. mubango were found in this same amount in addition to amines the triterpenes and / or steroids since phenols and alkaloids They were presented in moderate quantity and tannins in a mild way. It is concluded that the methanolic extracts of the plants evaluated present secondary metabolites in moderate to high concentrations. The metabolites found in these two plant species are of biological and pharmacological interest for their possible therapeutic applications in both animals and humans.
