Isolasi dan identifikasi senyawa metabolit sekunder dari akar jarak merah (Jatropha gossypyfolia), serta uji sifat toksik terhadap mikroba dan sitotoksiknya terhadap sel tumor telah dilakukan, Isolasi senyawa dikerjakan dengan menggunakan kromatograti kolom vakum (adsorben: silica gel, eluen: campuran n-heksan, etilasetat, kloroform, dan metanol). Identifikasi struktur dilakukan menggunakan teknik spektroskopi (F TIR, NMR-1 D,13C/DEPT, NMR-2D) dan membandingkan data tersebut dengan data sejenis yang telah dilaporkan. Sifat toksik dievaluasi terhadap bakteri Acetobacter sp., Eschericia coli, Staphylococcus aureus, dan Streptococcus sp., jarnur Aspergilus niger, Penicillium (grey), Penicillium sp. (wliite) dan Rlzizopus sp., serta sitotoksik pada sel murine leukemia P-388. Isolat yang diperoleh berupa kristal berbentuk jarum berwarna putih dan teridentifikasi sebagai jatrophone. Jatrophorie paling kuat menghambat pertumbuhan bakteri Acetobaclcr sp. dengan zona hambat 3,6 cm dan paling aktif terhadap fungi A. niger dengan zona hambat 4,4 cm. Sementara itu, sifat sitotoksiknya terhadap sel murine leukemia P-388 memperlihatkan sifat kurang aktif dengan nilai IC50 > 100 µg/mL.
