CAPSANTHIN

Description

Capsanthin is a carotenoid that has been found in C. annuum and has diverse biological activities. It reduces hydrogen peroxide-induced production of reactive oxygen species (ROS) and phosphorylation of ERK and p38 and prevents hydrogen peroxide-induced inhibition of gap junction intercellular communication in WB-F344 rat liver epithelial cells. Capsanthin (0.2 mg/animal) reduces the number of colonic aberrant crypt foci and preneoplastic lesions in a rat model of N-methylnitrosourea-induced colon carcinogenesis. It also reduces ear edema in a mouse model of inflammation induced by phorbol 12-myristate 13-acetate (TPA; ).

The Uses of CAPSANTHIN

Capsanthin may be used as an analytical reference standard for the quantification of the analyte in red pepper powder, red pepper fruits, paprika and oleoresin using chromatography techniques.

The Uses of CAPSANTHIN

antineoplastic

What are the applications of Application

Capsanthin is a natural carotenoid compound

Definition

ChEBI: Capsanthin is a carotenone. It has a role as a plant metabolite.

General Description

Capsanthin, also known as the red pepper carotenoid, is one of the major color pigments of paprika oleoresin, an oil-soluble extract, isolated from the fruits of Capsicum annum Linn or Capsicum frutescens. It is widely used as a color additive in food industries across the globe. The photoprotective effect of capsanthin protects human dermal fibroblasts against UVB induced DNA damage.

Hazard

A poison by skin contact.

Biochem/physiol Actions

Capsanthin is a potential nutraceutical, is found in green vegetables and is a constituent of paprika and asparagus. Capsanthin has been shown to exhibit anti-proliferative function.

Safety Profile

A poison by skin contact. When heated to decomposition it emits acrid smoke and irritating vapors.

Purification Methods

Possible impurities are zeaxanthin and capsorubin (below). Purify capsanthin by chromatography on a column of alumina (grade IV) and develop with 0.2% EtOH in *C6H6. It
