| Research Abstract |
Effectiveness of the methods for promotion of the activation of hydrolase andfor promotion of theoxidative coupling reaction was examined from the amount of indigo included in the leaves of natural indigo plants treated with various means. It was proved that the operations as the dry with a drier, the rubbing together by hand and the beating lead to an increase in indigo in the leaves of natural indigo plants. Next, it was examined whether the direct dyeing by using a crushed dry leaf of naturalindigo plants ispossible instead of thedyeingwith precipitation indigo or sukumo indigo. As a result, it has been confirmed that this simplified method of dyeing was very effective.The residues after the preparation of precipitation indigo from natural indigo plants proved to be applicable to the compost or the preparation of sukumo.
