To know thecompounds contained in the extract phytochemical test was conducted. The chemicalcompound test showed that extract of mangosteen rind contains phenolic/tannin/flavonoid,terpen/steroid dan alkaloid. The extracts inhibitated the growth of Aeromonas hydrophila,Edwardsiella tarda and Saprolegnia sp. to some extent. The optimal antimicrobial activitywas obtained from ethyl acetate.
