Abstract

Butea monosperma belongs to the plant family Fabaceae and also called “the flame of the forest” due to the bright orange and scarlet colours of its flowers. The compounds like; lanceoletin, butein, monospermoside and sulfurein have been isolated from petals of Butea monospermaflower which could be utilized as cosmetic treatment and so, it has got immense potential for use as herbal colour, which shall also create an additional income to tribe in the forest. The time of colour extraction using water was found to be long with less recoveryand poor quality extract. An experiment was conducted using steeping method of solvent extraction at ambient conditions with six treatments; T1: Normal tap water, T2: RO water, T2: Methanol (100%), T4: Methanol (50%), T5: Ethanol (100%) and T6: Ethanol (50%) to extract the colour from Butea monospermaflower. The time of extraction, dry dye recovery and dry dye colour content was measured for each treatment after extraction. The results of dry dye recovery, dye colour content and extraction time, indicated that the 50% v/v methanol solvent (Treatment-T4) has recovered highest dry dye of 0.310g per 100g flower and dye colour content of 179.25ppm compared to other treatments consistently with considerable extraction time of 22h 45 min.
