A wide variety of pigments, like chlorophyll, carotenoids and phycobiliproteins, which exhibit colours ranging from green, yellow, brown to red are present in algae. Increasing awareness of harmful effects of synthetic dyes and inclination of society towards the usage of natural products, such as plant / microbial based colours in food and cosmetics, has led to the exploitation of microalgae as a source of natural colours. Algal pigments have great commercial value as natural colorants in nutraceutical, cosmetics and pharmaceutical industry, besides their health benefits.
capsules are now commonly prescribed health foods for improving vitality and longevity of human beings. This review describes the distribution, structure of these pigments in algae, with emphasis on specific techniques for extraction and purification, along with different methods of biomass production and commercially feasible techniques documented in literature. An overview of the industrial applications of these natural colouring agents in diagnostics, food and cosmetics industry is also provided.

Although Brosimum gaudichaudii occurs in Amazon forest
and in Atlantic forest, it is the only species from the genus Brosimum found in
cerrado vegetation, with a very common occurrence. This species has been
exploited by pharmaceutical industry due to large accumulation of psoralens in
its roots. The stems and subterranean systems of seven fertile plants were
characterised in this study. At early stage of development the stems are
scandent and grow slowly before reaching arboreal size. The subterranean system
is composed of a xylopodium and a taproot. The xylopodium continuously produces
shoots that are able to turn into trunks. The taproot may grow up to one or two
metres deep. There are few lateral roots, but many radicles along the surface
of root system. Abundant latex is found in the pith and bark of branches and
young stems as well in the bark of the subterranean system. However, it is
scarce in the bark of mature trunks. The stem bark is grey, rough and thin,
while the bark of the root and xylopodium is orange, corrugated with laminate
surface. The xylopodium is a fundamental structure to understand the plant
strategies to successfully adapt to the cerrado environment condition.
