Advanced Materials Research, 2012
The effects of different pH values and temperatures on the dyeing behavior of three types of natural pigment (lac dyer red, gardenia yellow, gardenia blue) on wool fabric was determined. The optimal dyeing temperature was found to be 100degC and the optimal pH value was 4 when using the most suitable mordant, aluminium sulfate. After mordant dyeing the

Plant pigments as natural food colours
Endeavour, 1986Abstract The use of natural pigments derived from plants for colouring foodstuffs is now a commercial reality. This paper reviews the properties and the significance of the most widely used types based on flavonoids (largely anthocyanins), carotenoids, chlorophylls, betalaines, and others.

Chloroquine Resistance and the Nature of Malarial Pigment
Nature, 1965THE appearance of strains of human falciparum malaria resistant to chloroquine1 has stimulated investigations on the mode of action of this drug and on the mechanism of resistance to it. Although no morphological differences have been described between chloroquine-resistant and ordinary Plasmodium falciparum, a striking difference was observed in the ...

The polymeric nature of wine pigments
Phytochemistry, 1971Abstract During conservation and ageing of red wines, the grape anthocyanins initially responsible for wine colour are displaced, progressively and irreversibly, by more stable polymeric pigments, which account for up to 50 per cent of colour density within the first year.

Nature and Possible Significance of the Pigment in Fascioloidiasis
The Journal of Parasitology, 1960Infections of the large North American liver fluke, Fascioloides magna (Bassi, 1875) Ward, 1917, are characterized by black pigmentation of the host tissues. The pigmentation occurs in infections of various Cervidae, the common hosts, and to a greater extent in infections of the less common and less tolerant hosts, sheep and cattle.

, 2005 Racial differences in pigmentation and natural selection
Annals of Human Genetics, 1975The inheritance of skin colour in man is not well understood. A clearer understanding could be obtained by taking into account the biological basis and genetical control of pigmentation in other mammals, particularly the experimental species. In these, most of the loci governing pigmentation are pleiotropic, colour being only one of the traits affected
