2. 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;

3. 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.

4. 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 dye
b. lasting effect of the colorant

15. Conclusions
•The extracts from cornsilk have flavonoid contents and
thus could be made into a fabric dye.
•The intensity of the colorant was helped by CuSO4
which is chosen as the best mordant.
•The colorant made from the cornsilk extracts
has characteristics of a good fabric dye that is
comparable to that of the synthetic ones.

16. 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.
