The phytochemical investigations on the seeds of Raphanus sativus L. led to the isolation and identification of 15 compounds, including eleven sinapoyl derivatives (1–11), two terpenes (12–13), and two phenolic acids (14–15). All chemical structures were elucidated via 1H NMR and 13C NMR spectroscopic methods, and further supported by comparison with literature data. Compound 11 was isolated from the genus Raphanus for the first time. Notably, Compounds 7, 9, and 12–14 were reported in the Brassicaceae family for the first time. The chemotaxonomic significance of these compounds is discussed. •Compounds 7, 9, and 12-14were reported in the Brassicaceae family for the first time.•Compound 11 was isolated from R. sativus L. for the first time.•Sinapoyl derivatives could be considered as chemotaxonomic marker of vital importance for Raphani semen.•The chemotaxonomic significance of the compounds isolated from the Raphani semen was discussed.
