Indian dye yielding plants: Efforts and opportunities

Abstract

The present review article deals with the information on the dye‐yielding plants of India. Dyes are intensively coloured compounds that are applied to a substrate such as fibre, paper, cosmetics, hair, etc. to give colours and can be extracted from the roots, fruits/berries, bark, leaves, flowers, and stem/wood, fungi, and lichens by various processes of extractions. In addition to their dye‐yielding characteristics, many of these plants possess medicinal values and can be used for multiple other purposes. Plant derived‐colours have an important role in human life because of their safe and eco‐friendly nature. But due to the availability of economically cheaper synthetic dyes, the indigenous knowledge of extraction, processing, and proper utilisation has been diminished. Nowadays, the demand for natural dyes has been increased worldwide due to awareness about their beneficial properties. It has been essential that proper documentation and measure of conservation should be undertaken to preserve these natural dye‐yielding plants. This review article is an aid to a collective inquiry into Indian dye plants.

A Valuable Observation of Eco-friendly Natural Dyes for Valuable Utilisation in the Textile industry

“…In addition to its polyphenolic composition, Acacia catechu bark and wood dyes have Nilotic and babool bark, respectively. [19,25]…”

Biological Investigation on Novel Natural Dye Extracted from the Bark of <i>Calligonum polygonoides</i> L. and Their Application on Cotton Fiber

“…The remaining left after extraction of dyes are biodegradable and used as fertilizer [5]. Cotton fabrics treated with extracts of tannin-rich pomegranate coating provide UV protection [6]. Cellulosic (cotton) are frequently treated with tannins and probably display UV protection [7].…”

Environmental friendly application of ultrasonic rays for extraction of natural colorant from Harmal (P. harmala) for dyeing of bio-mordanted silk

“…So, these benefits have urged the traders to introduce such sustainable products in food, textile, cosmetics, pharmaceuticals, electronics, flavors, etc. 11,12 The world environmental agencies have spread awareness to use sustainable, green, and herbal based plant materials which have potential biomolecules (natural colorant) with excellent biological characteristics. 13,14 Due to the spread awareness for using such herbal-based bio-products (bio-colorants) by these associations, now people particularly the health-conscious community have started pressurizing the industrialist, traders, stake holders to introduce them in all fields.…”
