Аннотация:A new sulphur-containing compound, persicasulphide C, was isolated from the roots of Ferula persica, and its structure was characterised by 1D- and 2D-NMR spectroscopy as well as HRMS. In addition, closer inspection of NMR spectra of the previously reported polysulphides (persicasulphides A and B) revealed that their structures are slightly different from those reported. In this article, the correct structures of persicasulphides A and B are also presented.
