Carotenoids can help you to:

?

• Minimize the risk for certain types of cancer;
• Reduce the risk for CVD’s;
• Help to avoid cataracts.

?

They further:

?

• Have an important role in photosynthesis;
• Are powerful antioxidants in nature;
• Are used to attract animals (and humans) with their color.

Products

Our current Price List is containing all compounds presently in stock, including source and purity. These carotenoids can be delivered within a few days.

PRICE LIST

The carotenoids are prepared either by extraction from natural sources or by chemical synthesis. Samples are supplied in sealed ampoules, under nitrogen, to ensure stability. Usually purity (HPLC, % area) is ≥ 95%. Although the ampoules are labelled as 1 mg or 5 mg, these values are approximate. We guarantee, however, that the actual content will be not less than the stated amount. Whenever possible, they are supplied in crystalline form with the exception of (E/Z)-phytoene and (E/Z)-phytofluene which are oily at ambient temperature. All compounds are fully characterized and analytical data (HPLC, UV/Vis spectra) as a Data Sheet, as well as a Safety Data Sheet (SDS or MSDS) are provided with the samples.

In addition, we are able to prepare on request a large number of other carotenoids, including various (Z)-isomers, apocarotenoids, stereoisomers and esters. For more information see our

LIST OF SPECIAL COMPOUNDS

Carotenoids on this list must be reanalysed and can be delivered usually within weeks.

This range is expanding all the time! For unusual carotenoids and larger quantities, even if you don’t think it will be available, enquire! We will rapidly give you our assessment of whether it is feasible, how we would do it, and what we estimate it would cost.

Services

Demands for preparation of larger quantities (100mg or more) of carotenoids may be realized by our collaboration with a laboratory that is highly specialized in polyene and carotenoid synthesis. N.B. these products are not for human application.

In recent years there has been an increasing demand for?analysis?of carotenoids from plants, algae, fruits and other sources. We have established collaboration with a contract laboratory that is specialized in qualitative and quantitative analysis of carotenoids. We can establish readily an overview of the main carotenoids and measure the total carotenoid content.?Successful HPLC separations of various enantiomeric carotenoids on analytical scale are available. A number of analyses according to the needs of the customers and to their full satisfaction have been performed

Another service is?filling ampoules?under inert gas. The transfer of small amounts of carotenoids into ampoules may be very demanding. We have developed a procedure for filling manually ten to several hundred ampoules with a required amount.?This service is offered not only for carotenoids, though highly toxic compounds are excluded.

In the year 2000, CaroteNature?was started with the aim to distribute authentic samples of a large number of carotenoids for analytical purposes to researchers in the carotenoid field worldwide.?Since its foundation, CaroteNature?has grown steadily. We have exported our products to more than 60 countries all over the world and delivered to 175 universities. Our current stock of ready-for-shipment products includes almost 100 different carotenoids – the majority are available commercially only from our company. These figures clearly demonstrate that CaroteNature?is the worldwide leader in the distribution of carotenoids of high purity for analytical purposes.

We also offer services such as analysis of carotenoids in plant and other extracts, custom synthesis or isolation, filling ampoules under inert gas and consultancy in the field of carotenoids. We are cooperating with a number of laboratories of high reputation in the various fields of carotenoid research to ensure the high quality of our products and services.

CaroteNature?has been appointed sole distributor of the reprinted Volumes 1A, 1B, 2 and 3 of the book series ?Carotenoids“. In addition, also the ?Handbook“ and Volume 4 and 5 are available at CaroteNature.
