Abstract: This paper offers a broad overview on several natural dyes from plant origin. By this it is the fifth part in a series of review papers on natural dyes, their properties and infrared spectra. Basic information on origin of natural materials and dyes and their fields of application – especially in the field of textiles – is supported. The chemical structures of dyes are presented together with the measured infrared spectra (IR spectra) of 28 different dye products from various origin. A structure related discussion of the spectra is performed. Main aim of this overview is to offer a broad overview for people interesting in natural plant dyes. Further, the support of IR spectra is a helpful tool for material identification and quality control.
