“…As tanning agents, the tannins tan the pelt into leather. Whilst as a dye, the tannins impart a light brown [54,59] hue to the leather. The tannins in Acacia nilotica are considered a suitable tanning agent capable of producing good quality leather with high tensile strength, tearing strength, grain crack, shrinkage temperature, and flexing endurance [60].…”

The production of leather from animal skins and hides through tanning processes began in the pre-historic ages. Despite the origination of new leather making techniques such as chrome tanning which is being employed extensively today, the traditional method of leather production primarily through vegetable tanning is still being practised mostly in artisanal tanneries in developing nations including Ghana. Artisanal leather making, thus, contributes beneficially to rural livelihood. Nevertheless, the growth of this sector has been stifled by the lack of innovative technologies to enhance productivity. This challenge could be partly linked to the knowledge gap on the scientific principles governing artisanal leather production processes. This study, therefore, elaborates on various process steps and materials employed in traditional leather making in Ghana and the scientific principles underlying each of the processes. It also makes a comparison between traditional and modern leather manufacturing processes and identifies knowledge and technological gaps which would inspire in-depth scientific research into artisanal leather making.

“…This plant contain different types of bioactive components such as gallic acid, ellagic acid, isoquercitin, leucocyanadin, kaempferol-7-diglucoside, glucopyranoside, rutin, derivatives of (+)-catechin-5-gallate, apigenin-6,8-bis-Cglucopyranoside, m-catechol and their derivatives 16 . Traditionally A. nilotica pods are being used as a dye source for colouring the winnowing bamboo items and door panels 17 in some states of India. Pod of A. nilotica has rich source of phytochemical pyrogallol and pyrocatechol and good source for dyeing silk and other fibers in eco-friendly way with different mordants and mordant concentrations 17 .…”

Acacia is a genus of about 800 species of deciduous shrubs and trees and occupies the largest area of Rajasthan, Gujarat and the Deccan. About 25 species are of Indian origin. Some species of Acacia genus are commonly used in dying industries. Different parts of the plant Acacia nilotica are used in traditional medicine system due to their bioactive compounds. Hexacosanol (A), Lupa-12,20(29)-diene-3-one (B), Triacontanol (C) Stigmasterol (D) and Quercetin (E) natural compounds were isolated from methanolic extract of Acacia nilotica stem bark and characterized on the basis of different type of spectroscopic techniques i.e 1 H NMR, 13 C NMR, IR and MS.

For centuries, across West Africa, plants have been used extensively not only in traditional medicine but also for dyeing cloth. Examples are the use of the bark of Terminalia laxiflora, the root of Cochlospermum tinctorium and the pods of Acacia nilotica, which together form the vegetable basis of a complex natural colorant produced by the hunters of the Marka-Dafing community in the Mouhoun region of north-western Burkina Faso. This colorant, known as vouwo and used by the hunters to dye a hunting and ceremonial shirt called a donso dileke (hunter shirt), is prepared by adding the plant elements to soil and iron ore in water. This mixture of ingredients then undergoes a long process of fermentation, whereby an essential role is played by certain bacteria present in the mud. This paper examines the use of extracts of the pods of A. nilotica to counteract certain counterproductive bacteria that under non-optimal conditions may proliferate in the dyeing jar, forming thick biofilms and inhibiting the dyeing process. Besides showing some previously studied antibacterial activity, extracts of A. nilotica pods have also been found to interfere efficiently with the biofilm formation of these bacteria. By suppressing the disruptive bacteria, A. nilotica seems to support the proliferation and desired activity of the bacteria that contribute to the coloring of the textile (mainly anaerobic producers of iron sulphide). While extensive research has been carried out on the phytochemistry of traditional medicinal plants, in this ongoing study, the authors investigate the role of A. nilotica in traditional fermentative cloth dyeing by looking into aspects of the microbiome that develops during the dyeing of the hunter shirt. The interdisciplinary approach of this study to the complex roles of natural dyes combines extensive anthropological field research with microbiological methods.
