Artocarpous heterophyllus Lam heartwood dye is well known for its medicinal and dyeing properties since from ancient times. Isolation of the dye using both conventional and a green technique, microwave method was carried out. The conventional heating of (2+1) hour provided 4.64 % of the dye and by microwave irradiation at 160 W for (15 + 7) minutes, the yield obtained was 5.76 %. Both the dyes were found the same as evidenced by U.V, T.L.C and I.R. studies. The procedure developed can be used for the fast extraction of the dye of Artocarpous heterophyllus without affecting the nature of the product.
