curcumin

CAS No.

458-37-7

Formula:

C21H20O6

Basic Info

Curcumin (diferuloylmethane) is a bright yellow chemical produced by some plants. It is the principal curcuminoid of turmeric (Curcuma longa), a member of the ginger family (Zingiberaceae). It is sold as an herbal supplement, cosmetics ingredient, food flavoring and food coloring. As a food additive, its E number is E100.
It was isolated in 1815 when Vogel and Pelletier reported the isolation of a “yellow coloring-matter” from the rhizomes of turmeric and named it curcumin. Although curcumin has been used historically in Ayurvedic medicine, there is no evidence from clinical research that it has medicinal properties.
Chemically, curcumin is a diarylheptanoid, belonging to the group of curcuminoids, which are natural phenols responsible for turmeric's' yellow color. It is a tautomeric compound existing in enolic form in organic solvents and as a keto form in water.

12.1 Toxicity

  • Toxicity to fish: no data available
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

PURE CULTURE: 14C-Labeled curcumin, present at 1 mg/10 uL of N,N-dimethylformamide, was 75% biodegraded via ring cleavage of the catechol moiety when incubated for 3 days with a mutant strain of Phanerochaete chrysospporium, a white-rot fungi(1).

12.3 Bioaccumulative potential

An estimated BCF of 68 was calculated in fish for curcumin(SRC), using an estimated/ log Kow of 3.29(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of curcumin can be estimated to be 3400(SRC). According to a classification scheme(2), this estimated Koc value suggests that curcumin is expected to have slight mobility in soil.

12.5 Other adverse effects
