Statement of the Problem• The main goal of this study is to determine the effectiveness of maysin extracted from cornsilk (Maydis stigma) as fabric colorant.Specifically, it aims to obtain the following objectives:1. Determine the presence of maysin from mature cornsilk (Maydis stigma) using phytochemical testing;
2. Compare the color of the fabric colorant produced from extracts of mature cornsilk (Maydis stigma) using various mordant (CuSO4, alum, and combination of CuSO4 and alum) and choose the best color using survey method.
3. Using the best mordant compare the pure cornsilk solution with the solutions of cornsilk extract and other ingredients in a (ingredient: cornsilk), 50:50 ratio and the equivalent color of commercial fabric dye in terms of the following:a. color intensity of the fabric dyeb. lasting effect of the colorant

Conclusions•The extracts from cornsilk have flavonoid contents andthus could be made into a fabric dye.•The intensity of the colorant was helped by CuSO4which is chosen as the best mordant.•The colorant made from the cornsilk extractshas characteristics of a good fabric dye that iscomparable to that of the synthetic ones.
Recommendations• Search for other extraction methods in extracting the compounds from the corn.• Use other phytochemical tests to prove the presence of the flavonoid in the extract.• Obtain crude extract using rotary evaporator.• Use other fixing agents and increase the time of boiling the fabrics in the dye bath.• Utilize other parts of the corn that is to be put on waste to make a fabric colorant.
