2. What Is Emodin?
Emodin is a naturally occurring anthraquinone derivative widely studied as a bioactive plant compound. It exists primarily in the roots and rhizomes of traditional medicinal plants such as:
-
Polygonum cuspidatum (Japanese Knotweed)
-
Rheum palmatum (Chinese Rhubarb)
-
Polygonum multiflorum
In industrial applications, Emodin is classified as a botanical active ingredient rather than a finished drug. It is commonly used as a research compound, formulation intermediate, or functional ingredient in regulated industries.
