| Summary: | ,\'wuloncum koet;ape (Ateltaceae} or "Kecap1", tradlltonal r often used as medtcme and phytochemtcal exploratiOn al the S. koeuape lem•es has n01 hc>en wtdely U\ed. Therefore. tht'i research purpo•,ed to t'iolate and de!emune !he slruc!ure of \econdary metahollle\ from of S. koeuupe leave'• and detemme the anubactenu/ acl/vtty of pure compound\. 1\o/arwn of secondar_v metaholaesfrom S. koeljupe leave\ wa\ earned our rhrough se rera/ stages: extracTion, fracuonutton. and pzmficauon u.\mg mnou.\ clmmwtographu.: methods: lujwd vacuum chromaiOf!ruphy. grm•lfy chromatography. and radtal chromatography. The struclure determmauon of pure compound\• was earned out based on I f) and
