EUPATORY-EUPATORIUM ADENOPHORUM (YELLOWS & GREEN)
The genus Eupatorium belongs to the tribe Eupatorieae, the largest among the 13 tribes in the family Asteraceae comprising nearly 1200 species distributed in the tropical, subtropical and temperate regions of America, Europe, Africa and Asia.
E. adenophorum grows as weed in many parts of the world. There are many species of the genus Eupatorium that contain colourants; interestingly, the 1882 bulletin of the Royal Gardens, Kew, records two species known as Paraguay indigo. Considerable phytochemical studies have been done in Eupatorium spp., and altogether more than 300 chemical compounds have been reported from the genus including flavonoids, terpenoids, pyrrolizidine alkaloids, phenylpropanoids, quinonoids, phytosterols and sesquiterpene lactones, essential oils, and some others. Studies have shown that Eupatorium and its active principles possess a wide range of pharmacological activities, such as cytotoxic, antifungal, insecticidal, antibacterial, anti-inflammatory, and antinociceptive activities.
Leaves and stems extracts of E. adenophorum reported to exhibit antibacterial effect towards Proteus spp., Salmonella spp., Staphylococcus spp., Bacillus subtilis, B. thurengiensis, Enterobacter aerogenes, Salmonella paratyphi, Staphylococcus aureus, B. cereus, Proteus mirabilis; and water solvent extract showed antibacterial effect towards Peudomonas aeruginosa, E. coli, S. aureus, Staphylococcus spp., Citrobacter frundii, Proteus spp., Bacillus subtilis, Enterobacter aerogenes, Salmonella spp., Salmonella paratyphi, Bacillus thurengensis.
We employ the fresh E. adenophorum leaves powder form the local market to produce beautiful light to dark yellow & green shades on cotton, wool, silk and all natural textile substrates by standardized dyeing process using different combination of natural mordants on fibers, fabric and garments with excellent fastness properties.
