Phenolic compounds from rapeseed were extracted into 80% (v/v) methanol. The crude extract was then separated using size exclusion high-performance liquid chromatography (SE-HPLC) on a TSK G2000SWXL column with a mobile phase of 45% acetonitrile and 0.1% TFA (v/v). Six peaks were identified on the chromatogram: the main peak originated from sinapin. Calibration of the assay was characterised by an excellent linearity of the sinapin standard (r2=1.0). The method so described can be used for screening phenolic constituents in rapeseed or canola. It is also useful for the purification of the sinapin as a standard from the crude extract.

Związki fenolowe zawarte w nasionach rzepaku ekstrahowano 80% metanolem. Uzyskany ekstrakt poddano analizie metodą SE-HPLC na kolumnie TSK G2000SWXL. Fazą ruchomą był 45% acetonitryl (v/v) z dodatkiem 0.1% TFA. Na chromatogramie zanotowano obecność sześciu pików pochodzących od fenolokwasów i ich pochodnych. Głównym związkiem była sinapina. Kalibracja metody charakteryzowała się doskonałą liniowością wzorca sinapiny (r2 = 1). Opisana metoda może znaleźć zastosowanie w analizie przesiewowej składników fenolowych nasion rzepaku lub kanoli oraz przy oczyszczaniu standardu sinapiny z surowego ekstraktu.
