Anti-obesity active agent and Anti-obesity method

InactiveUS20100093847A1Anti-obesity activityIncrease heightOrganic active ingredientsCosmetic preparationsActive agentSubphylum
[Problem] Fucoxanthin extracted from wakame seaweed (Undaria pinnatifida) is effective as an anti-obesity active agent. However, fucoxanthin is contained in mature (adult) brown algae in a small amount, and accordingly, it takes a long time and high cost to obtain fcoxanthin in an amount sufficient for practical use. Further, an anti-obesity active agent showing a stronger effect has been desired. It is, therefore, an object of the present invention to specify a carotenoid exhibiting anti-obesity activity stronger than that of fucoxanthin and to provide an anti-obesity active agent and an anti-obesity method which use the caritenoid.[Means to Solve the Problem] Intensive and extensive studies have been made as to what carotenoid has an anti-obesity activity stronger than that of fucoxanthin and what material should be used in order to economically obtain such a carotenoid. As a result, the answer has been found that the carotenoid is fucoxanthinol. “Sea squirt (ascidian)” is a generic name of marine animals which belong to class Ascidiacea, subphylum Urochordata (Tunicata), phylum Chordata and which live nationwide. As described above, sea squirt (ascidian) is abundantly found as resources. In the present invention, fucoxanthinol is extracted particularly from internal organs and hard skins of sea squirt (ascidian), and it has been revealed that fucoxanthinol exhibits strong anti-obesity activity.

Artificial optimized culture method for sea squirt, microalgae and stichopus japonicus

The invention relates to an artificial optimized culture method for sea squirts, microalgae and stichopus japonicus. The artificial optimized culture method for sea squirts, microalgae and stichopus japonicus is a bio-remediation technology for realizing self-purification of a culture water body and a sustainable marine product culturing method by utilizing a biological mutual benefit mechanism of a seawater polyculture system. The bait microalgae are inoculated in culture seawater; and the stichopus japonicus and the sea squirts are put into the culture water body with increased microalgae biomass. The inorganic nutritive salt in the seawater is converted into the microalgae biomass through the bioconversion of the microalgae so as to provide abundant bait for cultured organisms and simultaneously increase the concentration of dissolved oxygen in the water body. The sea squirts filtrate a large amount of sea water to remove grains and excess microalgae in the water body and settle a large quantity of aqueous layer particulate organic matters into a substrate in the form of feces and false faces. The demersal stichopus japonicus with a detritus food habit ingest the organic debris, benthic diatoms and microorganisms in the substrate so as to improve a substrate environment and reduce water body pollution. The artificial optimized culture method for sea squirts, microalgae and stichopus japonicus utilizes the polyculture system to promote the culture proliferation of the stichopus japonicus, carry out the self-purification and remediation of the culture water body, and realize the sustainable development of stichopus japonicus culture industry.
