Abstract
In order to make pure dyestuff extract from polygonum tinctoria, we tried to traditionally-using cockle shell which the extracted water should be filtered in indigo for 8 hours and at the $40^{\circ}C$, and 4.0 pH. The 1.631g of powder dye could be produced when the 10.0 ml of aqueous ammonia was added into the solution, which had been filtered for 8 hours with the 300 g of indigo plant and the 2.51 of water. The main components of two maded -dye which has traditionally made of this and has purely made of that compared by TLC, HPLC, LC/MC techniques. Finally, the antibacterial activities and deodorization ratio of silk fabrics with natural indigo were carried out, too.
