PURPURIN Chemical Properties,Uses,Production

Chemical Properties

brown-red to brown powder

Uses

xanthin oxidase inhibitor, irritant

Uses

Purpurin is an anthraquinone derivative and is well known as a colour pigment derived from madder plants. Purpurin was extensively utilized in herbal remedies, in food colouring and dyes for cotton pr inting. Due to the high antioxidant activity exhibited by anthraquinone compounds, purpurin was determined through studies to possess potential radical scavenging effects. Purprin has also been shown to have inhibitory effects towards serine protease.

Uses

A xanthine oxidase inhibitor.

Uses

Purpurin is a naturally occurring reddish-yellow pigment found in madder root (R. tinctorum) that has been used both in herbal remedies and as food coloring. It can also by synthetically derived from 9,10-anthraquinone. Purpurin is protective against a number of food-derived heterocyclic amines in bacterial mutagenicity assays through its inhibition of CYP450-dependent N-hydroxylation and reduction of N-hydroxylamines. Purpurine can also inhibit (IC50 = 6.6 μM) spermidine-induced autoactivation of plasma hyaluronan-binding protein, a serine protease that can activate coagulation factor VII and prourokinase.

Definition

ChEBI: A trihydroxyanthraquinone derived from anthracene by substitution with oxo groups at C-9 and C-10 and with hydroxy groups at C-1, C-2 and C-4.

Purification Methods

Crystallise purpurin from aqueous EtOH, dry it at 100o. [Beilstein 8 IV 3568.]
