    Abstract: <i>Castanea crenata</i>, known as Korean chestnut has been used as a cosmetic material due to
its anti-wrinkle and anti-aging effects. <i>Artemisia capillaris</i> is well known as famous Traditional Chinese
Medicine (TCM) for treating acute and chronic hepatitis in China. In this study, the leaves of <i>C. crenata</I> and
<i>A. capillaris</i> were applied as natural dyes. In addition, the color patterns were compared by the pre-mordanting,
that is onchrome to silk fabric. Silk fabric was shown colors close to white by <i>A. capillaris</i> without any mordant
and with sodium tartrate plus citric acid. Interestingly, iron (II) sulfate and potassium dichromate induced green
as compared with other mordants inducing yellow or white. The composition of iron could induce very different
color changes. This study would be useful to obtain color changes by the leaves of <i>C. crenata</I> and
<i>A. capillaris</i> for some materials, e.g., cotton. Further study will be processed to evaluate them as a biological
usage.
