Marine gastropods of the family Muricidae produce Tyrian purple (6,6'-dibromoindigo; Cooksey 2001), a dye of significant historical importance that can be obtained from no other natural source (Westley & Benkendorff 2008).
2011), as is the case for some of the bioactive brominated indole precursors of Tyrian purple (Benkendorff 2013).
The biosynthetic origin of Tyrian purple which has been exclusively isolated from Muricidae molluscs is not currently known.
Alexander the Great (when giving imperial audiences as emperor of the Macedonian Empire), the emperors of the Seleucid Empire, and the kings of Ptolemaic Egypt wore Tyrian purple.
The imperial robes of Roman emperors were Tyrian purple trimmed in gold thread, while the badge of office for a Roman Senator was a stripe of Tyrian purple on a white toga.
After the main chemical routes leading to Tyrian purple were described the question about the biologic role of the hypobranchial secretions still remains open.
Information exists about the chemical composition of Tyrian purple obtained from P.
2000, 2001) studying the chemical compounds and their biologic function in egg masses of the Australian muricid, Dicathais orbita, found a range of brominated indole derivates, which were precursors to Tyrian purple.
pansa because of the Tyrian Purple exploitation, in this laboratory study the effect of periodically "milking" of P.
KEY WORDS: purple snail, Plicopurpura pansa, Tyrian purple
The majority of purple-producing marine snails belong to the family of Muricidae, and most, if not all, produce in the hypobranchial gland (also called mucus gland) a colorless secretion, which is ejected into the mantle cavity, and turns on exposure to air and light to Tyrian purple (Fretter & Graham 1994).
KEY WORDS: Plicopurpura pansa, purple snail, Tyrian purple
Recently described was the source and chemistry of Tyrian purple from the west Pacific marine snail species Plicopurpura pansa (Naegel & Cooksey 2002).
As in the Old World, the conservative Indian communities in Mexico are convinced that Tyrian purple possesses properties that cannot be duplicated, apart from the practical advantage that material dyed with purple does not bleach.
