Abstract:
This paper is based on the extraction, isolation and identification of yellow dye pigments present in jak saw dust (Artocarpus
heterophyl/us) by solvent extraction method. Six natural dye yielding plants were selected (Teak, Betel, Jak, Neem, Rambutan,
and Jaman) to identify the best dye yielding plant. Dyeing trials were carried out to find conditions of optimum depth and
stability. Extracts from the Jak gave the best dye shade on mercerized cotton fabric with best performances. This Plant is
abundantly available throughout in Sri Lanka. It has been reported that heart wood of jak fruit tree contains many
flavonoids.(l)
