ORTIZ-GUTIERREZ, Lina Johatzin et al. Use of Dalbergia palo-escrito as a vegetable alternative to rabbit tanned leather. Ecosistemas y recur. agropecuarios [online]. 2021, vol.8, n.3, e2967.  Epub Oct 31, 2022. ISSN 2007-901X.  https://doi.org/10.19136/era.a8n3.2967.

Evaluate the Dalbergia palo-escrito, as a natural tanning agent for rabbit skin. Two tests were carried out with extracts of D. palo-escrito, for the first, with leaf and stem, for the second the stem at different concentrations (20, 40 and 60 g L-1). With the extract, it carried out the tanning of rabbit skin, to evaluate color, texture and physical properties of the skin. The leaf and 60 g L-1 of stem extract decreased (P < 0.05) luminosity, while it did not affect the loss of weight and size of the skin. The loss of skin weight, firmness and fracturing increased with 40 g L-1; with 20, 40 and 60 g L-1 the loss of area and the proportion of size decreased, instead they increased softness, gloss and firmness. Concluded that the rabbit skins tanned with extracts of D. palo-escrito at a concentration of 40 g L-1, presented better physical quality.
