The Phytochemistry and The Anti-Bacterial Activity of Yellow Root (Arcangelisia flava Merr.) against Aeromonas hydrophila
Arcangelisia flava Merr had been long recognized by the Dayak community at Central Kalimantan. It was used for natural herbal due to its capability to medicate various diseases. It seemed that this plant was considered as having active substances that was useful for health. Therefore, f urther review on phytochemical components should be needed through screening and identifying the bioactive substance, and implementing a specific review about the solvent that was producing extract with high level of rendement and preventive zone. Result of the extraction of Yellow Root (Arcangelisia flava Merr) showed that the rendement rate of methanol solvent was the highest. The phytochemical screening of the extract result was aimed to ensure the presence of alkaloid, flavonoid, saponin, triterpen and tannin. Result of the test indicated that Yellow Root (Arcangelisia flava Merr.) contained of alkaloid, flavonoid, saponin and terpenoid compounds, while tannin was not detected. The use of chloroform solvent was producing the extract result with widest preventive zone (17.25 mm) on A. hydrophila.
