and Solanum aff. incomptum, traditionally used by the people of Quibdó, Colombia for this purpose, to identify new alternatives of sustainable use of the biological diversity and resources of the Colombian Pacific. Samples from shafts, leaves, seeds and fruits of the selected species were extracted using domestic chemical methods (salt, vinegar) to fix the extracted ink on different kinds of cloths and natural fibers (cotton, rayon, linen, among others). Natural colorants extracted with salt gave the best staining results. The extracted colorants achieved different tonalities from violet, lived, clear and dark, green, black coffee, dark red, rose, lilac, among others. These extracting methods are alternative ways to avail Choco’s tropical rain forest, to appreciate the traditional knowledge of these communities and could contribute to improve the region’s life quality.
