The research characterization of cytotoxic fraction against P-388 leukemia murine cells from the extract honje (Etlingera elatior) seed have been reported. This research lead to isolated and characterization of cytotoxic compounds against P-388 leukemia murine cells from the extract E. elantior seed. The extract of E. elantior seed was maserated by methanol, n-hexane, and ethyl acetate, respectively and estimated their cytotoxic activity against P-388 leukemia murine cell with 3- (4, 5-dimetiltiazol-2-yl) -2,5-difeniltetrazolium bromide (MTT) assay guided toxicity test against of shrimp Artemia salina Leach. Brine shirmp Lethality Test (BSLT) method. The active extracts will be separated by fractionation using column chromatography, radial chromatography, and for analyzing the purity of isolate will estimate by HPLC. The chemical structure of pure isolate will be identified by spectroscopies data UV Vis, FTIR, NMR and MS. The ethyl acetate extract from honje seed have cytotoxic activity by leukemia P-388 cell with IC50 19.21 µg/mL. The compound toxic as cytotoxicagainst P-388 leukemia murine cells is flavonoid compouds their is resveratrol, lapachol, apigenin, methylated chrysin, 6,2’-dihydroxyflavanone, 3-hydroxy-3,4’-dymethoxyflavone and 4’-hydroxy-5,7-dimethoxyflavanone.DOI: http://dx.doi.org/10.15408/jkv.v0i0.3640
Penelitian mengenai frofil fraksi sitotoksik terhadap terhadap sel murine leukemia P-388 hasil isolasi dari ekstrak biji honje (Etlingera elatior)telah dilakukan. Penelitian ini dimaksudkan untuk melakukan isolasi dan karakterisasi fraksi sitotoksik terhadap sel murine leukemia P-388 dari ekstrak biji E. elantior. Ekstraksi biji E. elantior dilakukan dengan cara maserasi menggunakan pelarut metanol, dilanjutkan dengan partisi menggunakan etil asetat, dan n-heksan, pengujian aktivitas sitotoksik terhadap sel murine leukemia P-388 dengan 3-(4,5dimetiltiazol-2-il)-2,5-difeniltetrazolium bromida (MTT) assay yang dipandu dengan uji toksisitas terhadap larva udang Artemia salina Leach. menggunakan metode Brine Shirmp Lethality Test (BSLT). Ekstrak paling aktif difraksinasi menggunakan kromatografi kolom, dan uji kemurnian dengan KLT. Senyawa murni hasil isolasi diuji aktivitas sitotoksik dan dikarakterisasi dengan metode spektroskopi UV-Vis, FTIR, , dan LCMS.Ekstrak etil asetat biji honje memiliki aktivitas sitotoksik terhadap sel leukemia P-388 dengan IC 50 sebesar 19.210 µg/mL. Berdasarkan analisis menggunakan MassLynx software (Version 4.1) serta database Massbank dan Chemspider secara online, fraksi yang menunjukkan sifat sitotoksik terhadap sel leukemia P-388 dengan nilai IC 50 19.555 µg/mL diperkirakan merupakan campuran beberapa senyawa golongan fenolik seperti resveratrol dan jenis flavonoid diantaranya lapachol, apigenin, methylated chrysin, 6,2'-dihydroxyflavanone, 3-Hydroxy-3,4'-dymethoxyflavone dan 4'-Hydroxy-5,7-dimethoxyflavanone.
