The Antimicrobial Activities of The Extracts of Red Fruit (Pandanus conoideus Lam.) Pre-dried by Détente Instantanée Contrôlée (DIC)

Red fruit (Pandanus conoideus Lam.) is an indigenous plant from Papua Province, Indonesia. Local communities believed that fruit of P. conoideus Lam. can treat several degenerative diseases such as cancer, arteriosclerosis, rheumatoid arthritis, and stroke. DIC is a high-steam pressure treatment, is also categorized as a HTST (High Temperature Short Time) process. In this study, the antimicrobial activity of the etanolic and the hexane extract of red fruit pre-treated and untreated by DIC, and the red fruit oil are observed. The red fruit oil and all the ethanolic extract obtained from the red fruit powder pre-treated and untreated by DIC do not show an inhibitory activity toward Escherichia coli and Staphyloccoccus aureus. Also, the hexane extract from DIC pre-treatment does not show an inhibitory activity toward Escherichia coli and Staphyloccoccus aureus, whereas that of the untreated shows an inhibitory activity, but is not as potent as amoxicillin.
