Description
Summary:There is growing interest in the chemical composition of plants towards discovery of more effective biotherapeutic agents. Six bioactive compounds were evaluated from Hibiscus sabdariffa and Syzygium samarangense juice extracts. Both juices had high amounts of saponins, with Syzygium samarangense having higher content (4.77%) than Hibiscus sabdariffa (1.46%). Microbial counts in the juices were in the range of 104 cfu ml-1 of ethanolic extract. The juice extracts showed significant (P≤0.05) antimicrobial activities against Escherichia coli , Salmonella typhi and Candida albicans , implying that the juices possess both antibacterial and antifungal properties. The results give substantial scientific credence to the current therapeutic uses of these plants. La composition chimique des plantes s'avère d'une importance capitale dans la découverte des agents biothérapeutiques plus efficaces. Six composés bioactifs des jus extraits de Hibiscus sabdariffa et Syzygium samarangense étaient évalués. Les deux extraits de jus contenaient tous de quantités plus élevées de saponine, avec 4.77 et 1.46 % pour Syzygium samarangense et Hibiscus sabdariffa, respectivement. Le dénombrement microbiendans les jusavoisinait 104 cfu ml-1 d'extrait d'éthanol. Les extraits de jus ont montré des activités antimicrobiennes significatives (P≤0.05) contre Escherichia coli , Salmonella typhi et Candida albicans , signifiant que les deux jus possèdent tous des propriétés antimicrobiennes et antifongiques. Les résultats font montre d'une crédibilité scientifique substantielle eu égard aux usages thérapeutiques courants de ces plantes.>
