Optimum Conditions for Extraction of Antibacterial Compounds from Citrus Aurantifolia Fruit Peel Waste
Abstract: Citrus fruit peel is
a major waste in citrus fruit processing industry. The research on extraction
active compounds of Citrus aurantifolia (lime) fruit peel waste and
antibacterial activity assay has been done. The aim of research was to get
optimum condition to extract their active compounds which have antibacterial activity.
The dried lime fruit peel was extracted by maceration method using ethanol 48%,
72%, and 96%. The dried and fresh lime fruit peel were also extracted using
ethyl acetate. Antibacterial assay was done by diffusion agar against Staphylococcus
aureus ATCC 25923 and Escherichia coli ATCC 25922. The result showed that
optimal condition to extract antibacterial compound using fresh sample with
ethyl acetate as solvent. The ethyl acetate extract of fresh sample was more
active against S. aureus than E. coli.
