Abstract
This research investigated the use of five local plants in Northern Thailand which were Camellia sinensis (CS), Moringa oleifera (MO), Oroxylum indicum (OI), Schefflera leucantha (SL), and Tinospora cordifolia (TC) as stabilizing agents for indigo dyed fabric. The selected plants were extracted and examined for phytochemical compositions. It was found that CS-extract revealed the highest content of total phenolic compound, flavonoid and tannin of 2.400.46 GAE/mg DW, 3.31+-0.29 QE/mg DW, and 0.23+-0.01 ECGC/mg DW, respectively. MO total phenolic compound, flavonoid and tannin of 0.96+-0.04 GAE/mg DW, 1.81+-0.15 QE/mg DW, and 0.15+-0.02 ECGC/mg DW, respectively. For antioxidant properties, CS and MO exhibited the most efficiency of 6564.4+-55.6 mM Fe2+/g DW and 6512.6220.6 mM Fe2+/g DW, respectively. Consequently, these might be responsible for the ability for color fixation. Particularly, MO with the excellent properties resulted in a good color fastness score at 3-4. In contrast, CS seemed to be less fixative ability than MO.
